Products


Lallemand offers over 100 oenological yeasts selected throughout the world. In North America we have over 40 of the more successful yeasts to meet your creative needs while working within your specific winemaking practices.

These following brief descriptions will provide general information on each yeast and what sets it apart from the others under standard winemaking conditions. Also use the Yeast Chart and the Grape and Yeast Cellar pairing guide to help you select the right yeast to fit your grapes, fermentation conditions and stylistic goals.

Malolactic Bacteria Selected from Nature
Lallemand offers two formats of freeze-dried bacteria cultures in North America along with MaloTabs--bacteria in tablet form..

MBR®
The MBR® form of malolactic bacteria represent a Lallemand acclimatization process that subjects the bacteria cells to various biophysical stresses, making them better able to withstand the rigors of direct addition to wine. The conditioned MBR® bacteria that survive are robust and possess the ability to conduct reliable malolactic fermentation (MLF), even under difficult wine conditions.

1-Step®
The 1-Step® starter kit is a highly effective malolactic starter culture to promote MLF in most red and white wines in a wide range of oenological conditions. The kit contains one of our popular MBR® bacteria and an activator mix that require a short acclimatization protocol to wake-up the bacteria and activate their metabolism.

Unlike the MBR® cultures, the 1-Step® cultures are not preconditioned at our Lallemand bacteria facility and therefore require a simple rehydration/activation step 24 hours before they can be inoculated into the wine.

Popular MBR® bacteria strains, Enoferm® ALPHA, BETA,  Lalvin VP41 and PN4, are now available as 1-Step® starter kit cultures. The 1-Step® cultures perform as well as or better than MBR® cultures, especially under more challenging MLF conditions.

 

NUTRIENTS FOR ALCOHOLIC FERMENTATION

Since Lallemand began producing yeast in the early 20th century, we have understood the importance of providing growing yeast the nutrients they need to survive and reach their maximum potential. Experiences in our own yeast production fermentations laid the groundwork for our nutrient formulations. We have also collaborated with others in the area of yeast growth nutrition and fermentation to attempt to understand the complex and often frustrating interactions in grape must.

Lallemand offers three classifications of yeast fermentation nutrients:

1. Nutrients and Protectants Added to Yeast Rehydration Water
2. Complex Yeast Nutrients for Use During Fermentation
3. Other Yeast Nutrients for Use During Fermentation.

 

ENZYMES

Lallemand offers winemakers a complete range of high-quality enzymes to meet winemaking needs and international quality requirements. Lallemand's expertise in winemaking applications focuses on a tailor-made approach that involves:

  • Investigating winemakers' needs throughout our worldwide network
  • In-depth analysis in our enzymology laboratory of all available raw material enzymes
  • Elaborate testing of experimental products at technical institutes and wineries throughout the world
  • Developing new products for specific winemaking applications. Lallzymeâ"¢ microbial-origin enzymes are utilized in winemaking for:
    • Clarifying musts and wines
    • Macerating grapes
    • Increasing the filterability of musts and wines
    • Releasing flavor components
    • Macerating yeast

In addition to these applications, lysozyme sourced from egg whites is approved for lactic acid bacteria management in winemaking.

 

OTHER PRODUCTS

The use of immobilized microorganisms in foods has been developing for over 20 years. The immobilized microorganisms have the advantage of being easily introduced and removed from the culture media after total or partial biotransformation of the substrates. One of the typical techniques for the immobilization of microorganisms is encapsulation: this consists of coating the microorganism in a rigid alginate matrix. The technological advances of Proenol® encapsulated yeast cells in alginate gel, a natural polysaccharide extracted from seaweed, enables the substrates and metabolites to diffuse throughout the gel without releasing the yeast cells into must or wine. In the case of our encapsulated yeast, the primary benefits are convenience and improved wine quality by keeping spoilage and processing at a minimum.

Rehydration Protocol - Lallemand
Rehydration Protocol - Lallemand
Rehydrating your selected yeast prior to inoculation is a key step for success. Follow these easy steps for rehydration to encourage a healthy fermentation.

NO.1 CO-INOCULATION

Co-inoculation is the practice of inoculating selected wine bacteria at the beginning of the winemaking process shortly after yeast inoculation, usually 24 to 48 hours after yeast inoculation. This technique is advantageous because not only will it secure the malolactic fermentation (MLF), but also because there are definite advantages that are recognized by winemakers and professionals.

For a successful co-inoculation, some parameters are crucial for its success – choosing the right wine yeast, correctly rehydrated, good temperature management and the proper yeast nutrition strategy are keys point to integrate for any fermentations. Well-fed and heathly wine yeast and bacteria lead to complete and regular alcoholic and malolactic fermentations.

Based on 20 years of experiences, and from the results of many collaborations between Lallemand and research center from France, Spain, Italy, South Africa, Argentina and Germany has shown the benefits of co-inoculation with either Oenococcus oeni or Lactobacillus plantarum.

Lallemand simplifies the process of restarting stuck fermentations, with Uvaferm 43 Restart™
26 September, 2016

Building on its experience as a producer of wine yeasts, Lallemand has developed a production process that makes yeast naturally more resistant to stress caused by high alcohol content and other hostile conditions related to stuck fermentation. Lallemand now offers a new choice for restarting the fermentation process: UVAFERM 43 RESTART™.

Benefits of UVAFERM 43 RESTART™ yeast

When fermentation stops mid-stream, the must generally contains much more fructose than glucose, the form of sugar that yeasts prefer. The ideal solution up to now has been to use an alcohol-tolerant fructophillic yeast with a high fermentation capacity, such as Lallemand’s Uvaferm 43™, selected by Institut Rhodanien in France.

Thanks to an innovative pre-acclimatization process developed by Lallemand and tested and approved by Institut Rhodanien, the yeasts’ resistance to toxic conditions of stuck fermentation is naturally increased. The UVAFERM 43 RESTART™ yeast cells are more robust and acclimatize more quickly after inoculation. This in turn greatly simplifies the process of restarting the fermentation.

Combined with good oenological practices, UVAFERM 43 RESTART™ enables winemakers to effectively resolve most stuck fermentation problems in a few steps while helping to preserve the quality of the wine.

New, innovative and natural options to viticulturists and winemakers
15 June, 2015


LalVigne® is a new product line from Lallemand’s worldwide research and development network. It provides new, innovative and natural options to viticulturists and winemakers that were unknown until now.

WHAT IS IT?

LalVigne is an organic yeast derivative product that is applied in the vineyard as foliar spray at veraison. The yeasts used in its production were sourced from the Lallemand wine yeast collection. A single vineyard treatment with a LalVigne spray consists of two applications. The first is done at 5% veraison and the second 10–12 days later. 

LalVigne is easily suspended in water and applied using a spray rig or hand sprayer. In warmer wine regions ideal conditions for spraying are before the heat of the day. In the cooler regions, a window of 24 hours between rains is needed to get maximum effect. Intermittent rain after this point will not affect the effi cacy of the product.

 

WHY USE IT?

All winegrowers face the harvest challenge of achieving phenolic and enological maturity at the same time. Application of LalVigne has been shown to encourage the concentration of aroma precursors in grapes and it can have a noted impact on the timing of the phenolic maturity.

 

Cool Climate Scenario

In cooler climates, phenolic maturity can be diffi cult to reach. Complicating factors can include the onset of rain, early frosts, the grape variety itself, and vines susceptible to Botrytis. In many cases, the harvest date ends up being determined by external factors and not by grape maturity. 

A 2014 Washington State trial involved treating a Merlot vineyard with LalVigne. In this trial, the winemaker picked the treated vineyard six days earlier than the control block. Picking was done based upon the winemaker’s judgment about the fl avor and perceived phenolic maturity of the grapes. Wines made from the treated and control blocks demonstrated strong similarities, despite the large disparity in harvest dates. The opportunity for the winemaker to harvest a week earlier and achieve the “same” wine greatly reduces the risk of quality loss, due to unforeseen weather conditions.

 

Warm Climate Scenario

In warm climates, optimal sugar levels are often reached far in advance of other critical factors such as phenolic maturity. This means that the harvest date is often chosen primarily due to potential alcohol levels rather than other wine quality parameters.

Trials were done on Merlot and Cabernet Sauvignon in one of the warmer growing regions in California.

For both varieties, the control and treated blocks were picked at the same time. The decisions to pick were based on sugar levels. Blind sensory tastings showed differences in color, mouthfeel and aromas, with tasters preferring the wines that were treated with LalVigne. The vineyards yielded 10 tons/acre, thereby allowing the winery to improve maturity on vines with heavy yields.

 

WHERE IS IT USED?

For the last several years, Lallemand has been conducting trials with LalVigne sprays in vineyards all over the world. The goal was not only to establish effi cacy, but also to gauge enological impacts that may not have been observed in the lab.

 

Observed Impact on Mouthfeel and Volume

The trial below (Figure 1) was conducted on Merlot and Syrah vines in Languedoc in 2012. A tasting was done by 20 professionals at the Centre de Viticulture et d'Oenologie de Midi-Pyrénées. In the LalVigne treated Merlot and Syrah, an increase in mouthfeel and volume was observed. The Merlot also showed an increase in aromatic intensity.

Observed Impact on Aromatic Intensity

A Sauvignon Blanc trial done in Spain in 2012 (Figure 2) was tasted by a panel of 20 professional winemakers. The wine made from the LalVigne treated vineyard scored better in mouthfeel, roundness and aroma complexity.

In 2013, trials were done on Sauvignon Blanc in the Southern Hemisphere. Laboratory analysis on the LalVigne treated samples showed an increase in thiols.

Observed Impact on Green Characters (IBMP)

The natural decrease of methoxypyrazine (3-isobutyl-2-methoxypyrazine) or IBMP, during the ripening phase is a good indicator of aromatic and phenolic ripeness for grapes. It has been observed that virtually all the IBMP present in grapes ends-up in fi nished red wines, regardless of winemaking practices. Thus, vineyard practices have a huge impact on fi nished wines.

Trials from the 2014 U.S. harvest were tested for differences in IBMP. It was observed that wines from the LalVigne treated vineyards showed a trend toward lower levels of IBMP. Furthermore, as we increase our trials, the trend seems to be that a greater reduction of IBMP is occurring when the baseline amount of IBMP is higher. Figure 3 below illustrates this.

Evaluation of the impact of a fungal-origin chitosan preparation (No Brett Inside) on Brettanomyces for wine aging
13 October, 2014

Brettanomyces  bruxellensis  development  in  wines  is  a  continuous  threat  for  wine  quality . This  undesirable  yeast  is able to develop during aging under difficult conditions, and to produce negative aromatic compounds such as volatile phenols related to sensory descriptors as animal-like, horse, barnyard, band aid and medicinal. Chitosan of fungal origin has been introduced as a new potential tool to control Brettanomyces in winemaking [1]. Recent studies showed the impact of chitosan application (racked off after 10 days) on contaminated wines, leading to the elimination of Brettanomyces cells [2]. Due to the necessity to control wine microbiological stability during aging in barrels, our research focuses on a new, long term application of an enological chitosan preparation, to prevent wine from Brettanomyces along the aging period (up to 9 months) at both experimental winery and at winery-scale.

Lallemand Presents - SO2 Production By Wine Yeast During Alcoholic Fermentation
05 August, 2014

Sulphur dioxide is used during several steps of the winemaking process. It is added to prevent the unwanted development of microorganisms, and as an anti-oxidant to inhibit polyphenol oxidases (laccase and tyrosinase).

However, sulphites may have a negative impact on wine sensory properties, can delay the onset of malolactic fermentation, and can cause some health concerns in case of high concentrations in the final wine or due to human sensitivity. That’s why SO2 levels in wine are regulated. With the introduction of innovative yeast, managing sulphur compounds (SO2 and H2S) during fermentation can be a strategic decision.

Lalvin ICV OKAY®: A new approach for the molecular basis of sulfide and sulfite production by wine yeasts
18 July, 2014

Enological yeasts contribute greatly to the final aromatic balance of wines through the production of volatile compounds of interest; nevertheless, they can also be responsible for the production of negative off-flavours, such as sulfur compounds. Sulfite and sulfide are two of those compounds whose production has to be controlled. The sulfate assimilation pathway has been widely studied, however, little is known about the molecular basis responsible for the differences in sulfite and/or sulfide production between yeasts strains. In this project, we implemented a QTL mapping approach to identify the genetic determinants of the low SO2 production of a wine yeast strain.

A New Tool to Fight Against Brettanomyces and Preserve the Aroma of the Wine
20 May, 2014

Brettanomyces bruxellensis are a threat to wine quality. These yeasts are capable of developing in difficult media (high alcohol, nutritional deficiencies, high SO2), at all stages of vinification and are responsible for the production of undesirable aromatic compounds: volatile phenols (4-ethyl-phenol, 4-ethyl-guaiacol, 4-ethyl-catechol). These compounds give rise to the perception of disagreeable ‘animal-like’ notes (leather, stable, barnyard) or pharmaceutical notes (Band-Aid medicinal).

Even at low population levels (1 to 1000 CFU/mL), Brettanomyces constitute a threat, as they can produce these volatile phenols at any moment. When the concentrations of these phenols are weak or below perception thresholds, they can mask the wine’s bouquet and compromise its varietal expression, and its intensity. In many regions, the volume of wine affected by Brettanomycesis relatively significant.

Currently, different preventive means are implemented to fight against Brettanomyces:

  • Good management of SO2related to the wine pH
  • Optimized alcoholic and malolactic fermentations
  • Lees management,
  • Barrel hygiene and storage…

But these means are not always effective. No Brett Inside (chitosan of fungal origin) represents an innovative and efficient tool for fighting against Brettanomyces.

Varietal Aromas Resulting from Alcoholic and Malolactic Fermentations
24 April, 2014


The interaction between microorganisms and the grape must is a complex mechanism involving a multitude of substrates and products, including some that have major sensory impacts. The nutrients present in the grape must (e.g., carbon, oxygen, nitrogen, sulphur and phosphorus compounds, vitamins, minerals and trace elements) create the conditions necessary to ensure the proliferation of microorganisms. Particularly, microorganisms use the sugars and amino acids, which have the metabolic effect of producing multiple metabolites from non-volatile esters (mostly polyols and acids) and volatiles esters (e.g., alcohols, aldehydes and ketones, fatty acids, sulphur and phenols), which also impact the aroma and the “bouquet du vin” (Swiegers et al. 2005). The microorganisms interact with, notably, the various aroma precursors present in the grape by targeting, more specifically, the glycosides, conjugated cysteine and the phenolic compounds (Eglinton et al. 2004, and Dillon et al. 2004).

This issue of Winemaking Update summarizes the XXIVes Entretiens Scientifiques Lallemand. These scientific meetings, held in 2013, discussed the impact of wine yeasts and bacteria on varietal aromas.

Learn about the amazing biological system that occurs in the process of grape growing
22 January, 2014


The microflora of grapes form a complex biological system where a great variety of yeast's, fungi, and other bacterias interact in many ways. Then during the pressing of the grapes, the biofilm on the grapes' surface is put into contact witht the juice. With the contribution of the microorganisms in the winery, this new environment is a fully active medium. Through the complex interactions of inhibition and stimulation occuring among the yeasts and bacteria the must is gradually transformed into wine.

A REVOLUTIONARY YEAST WITH VERY LOW SO2 AND OTHER NEGATIVE SULPHUR CONTAINING COMPOUNDS PRODUCTION
11 September, 2013

Toulouse, France, April 2, 2013 – Resulting from a collaboration between Lallemand and the ICV-INRA-Sup’Agro (France), the Lalvin ICV OKAY ® YSEO® yeast is a hybrid obtained by directed breeding between two Saccharomyces cerevisiae using the quantitative trait loci (QTL) method associated with the production of SO2 and other sulphur containing compounds.

Because of its very low nitrogen requirements and excellent resistance to extreme temperatures (from 12°C to 14°C minimum and 28°C to 30°C maximum), Lalvin ICV OKAY ® yeast conducts regular and complete fermentation, even with very ripe grapes.

Lalvin ICV OKAY ® offers a real advantage to the winemaker: it produces very little acetaldehyde and consequently, there is a better SO2 management by reducing the doses normally required. Its volatile acidity also remains low even under difficult conditions (high alcohol, low NTU, difficult temperatures).

Because it was selected specifically for its ability to produce very little SO2 and other negative sulphur compounds, the use of Lalvin ICV OKAY ® will result in wines with a clean sensory profile. The wines are more focused on the fruit characters, with more volume, as well as reduced dryness and bitterness

With Lalvin ICV OKAY ®, winemakers now have the opportunity to better manage SO2 levels, while maintaining stable and high-quality wines.

GO-FERM PROTECT EVOLUTION®: A NATSTEP® YEAST PROTECTION DESIGNED SPECIALLY FOR WHITE AND ROSÉ WINE CONDITIONS
15 May, 2013

Toulouse, France, May 6, 2013 – Lallemand continues to innovate with a new solution for yeast protection, developed to meet the specific needs of the often difficult fermentation conditions of white and rosé wines. Go-Ferm Protect Evolution® – part of the Natstep® line of patented products – was designed to ensure the vitality and viability of wine yeasts used in white or rosé wine fermentation.

The special inactivated yeasts in Go-Ferm Protect Evolution® are natural sources of ergosterols, vitamins and magnesium, and increase yeast vitality and ethanol tolerance. These nutrients are often missing during white or rosé fermentation due to clarification and other pre-fermentation treatments. When added during rehydration, they are absorbed into the yeast membranes. As shown in many scientific studies, a healthy yeast membrane is key for the ability of wine yeast to carry out regular and complete fermentation, and to survive the difficult winemaking environment. Moreover, the specific formula found in Go-Ferm Protect Evolution® has repeatedly demonstrated significant increases in the levels of volatile thiols (3MH and 3MHA) in such varietals as Sauvignon Blanc and Colombard. Furthermore, the impact of Go-Ferm Protect Evolution® on yeast viability until the end of alcoholic fermentation is even greater than an oxygen addition performed at one-third point of the fermentation.

Rehydration with added Go-Ferm Protect Evolution® facilitates white and rosé wine fermentation and increases volatile aromatic compounds such as thiols. It also helps eliminate the need for added oxygen during fermentation and influences positively the final quality of the wine.

Stuck Fermentation Help
17 October, 2012

Once again it's that time of year. Our phones are ringing off the hook with stuck fermentation calls. Too many calls, so many problems, and not enough hours in the day! So we put toether a new section of the website called "the laboratory" where you can go for help with fermentation problems. We hope that the sage advice from Lallemand's Yeast Guru, Clayton Cone, and his lackeys will help you solve (or hopefully avoid) fermentation problems.

Oenomag Volume 1, Number 3 - Now Available for Download

In search of the essential.  27,000. That's how many times the words mineral and minerality appear in the more than 259,000 reviews on www.winespectator.com. That’s twice as often as the word fruity. During the most recent Lallemand Tour with the theme “Minerals and Wine” from January 17 to 20, international wine journalist Cees van Casteren showed that, indeed minerality has become more than just a passing fad or trend in the world of wine.

The terms mineral and minera-lity have become increasingly important—so much so that they have become ubiquitous in wine tasting. But why the infatutation with minerality? During the Lallemand Tour seminars, aroma sculptor and selfproclaimed philosopher Michaël Moisseeff introduced a new way of thinking. Perhaps the omnipresence of minerality is in reponse to our pressing need to fi nd the essential, as if our senses were rejecting the excessive amounts of noise, colours, smells, and tastes that we face on a daily basis. Minerality is reminiscent of vanitas art, a genre that was popular in the Baroque period when vanity and opulence ran rampant. Vanitas paintings make reference to death, resurrection, time, sand, and all things timeless.

29 May, 2012

Montréal, May 16, 2012 – Another Lallemand product is now listed to comply with the OMRI Standards Manual and the OMRI Policy Manual, which are based on the requirements of the USDA National Organic Program Rule (7 CFR Part 205). The approved product for OMRI listing is Reduless® ..

Reduless® is a unique yeast derived product with immobilized copper developed to reduce sulphur compound off-flavours and improve wine quality. It will reduce levels of hydrogen sulphide, diethyl sulphide, dimethyl sulphide, mercaptans and other sulphur related off-flavours in wine. Those compounds can lead to strong negative assessment by consumers and depreciation of the wine. Reduless® can be used on red, white and rosé wines and will enhance overall quality and fruity character of the wine by reducing its vegetal and reduction notes. The mouthfeel character is also improved.

This new OMRI approval is an important and continuing step for Lallemand as it provides organic winemakers with quality products. Reduless® will join join other OMRI listed products such as Opti-White®, Opti-Red®, Optilees®, Go-Ferm® Protect, Fermaid O™, GoFerm®, Noblesse™ and Fortiferm®..

MALOLACTIC BACTERIA: EFFICIENT CONTRIBUTORS TO WINE STYLES
10 May, 2012

The evidence is stronger than ever. Malolactic bacteria are important tools to influence the sensory profiles of wines. It has been long known that malolactic bacteria (ML) are essential to reduce the acidity of wine through malolactic fermentation. But now, our on-going research is showing their sensory potential as well. Whether a Chardonnay is more or less buttery, or a red wine has intense red berry aromas are now confirmed by numerous trials and research results.

1. Accentuate the fruitiness of red wines

The effects of malolactic fermentation (MLF) on wine aroma and chemical properties of Australian Cabernet Sauvignon at the AWRI were explored by inoculation with different selected Oenococcus oeni. Significant compositional differences occurred in response to the different MLF treatments and strain dependent changes in volatile aroma compounds were observed. Increases in fruity esters were associated with increases in fruit related sensory attributes. These trends were observed over three vintages in Cabernet Sauvignon fruit sourced from various vineyards (Figure 1).

The impact of the ML bacteria starter is important, but it is also adapted to the different terroir, making the wines all different from one another due to the terroir effect. In all cases, ML bacteria are able to modulate the red berry aromas to different ... read more.

Specialty Inactivated Yeast Enriched in Glutathione
08 November, 2011

The utilization of specialty inactivated yeasts (SIY) in winemaking has gained popularity in recent years, and their uses are varied. For example, SIY can be used as protectors during yeast rehydration and as a nutrition tool during fermentation. As we understand more about the yeast cell constituents, the production process, the characterization of each yeast strain and their unique fractions, we can obtain very specialized inactivated yeasts to yield specific results under defined conditions. Such is the case for the inactivated yeasts that can trigger specific responses during fermentation due to their unique functionalities. This issue of Winemaking Update will focus on a new SIY designed for white and rosé wines.

1. A quick review: What are inactivated yeasts?

An inactivated yeast preparation is a dry product made from oenological yeast that has been treated to suppress its fermentation capacity. The inactivated yeast material is then processed using different techniques, such as enzymatic and/or physicochemical ... Click Here to read the full Winemkaing Update PDF


From Theory to Practice: Sugar to Ethanol Conversion by Wine Yeast
13 October, 2011

Andrew Markides, our colleague in Lallemand Australia has written a number of Technical Notes. Technical Note 803A reviews sugar to ethanol conversion by wine yeast - from theory to practice. One of the basic conclusions is that for 56 tested wine yeast strains, the differences in sugar to alcohol conversion vary no more than 0.51% v/v of alcohol.

Some basic observations reported in the literature:

 

 

  • It is a known fact that YEAST (type & strain), vary in their ability to utilise carbohydrates in the formation of ethanol and other by-products

  • The Gay-Lussac Equation 

    C
    6H12O6  -----> 2CH3CH2OH + 2CO2

    180g Sugar is converted to 92g Ethanol and 88g Carbon Dioxide.  
    BUT, this can only be achieved if there is no yeast growth and ethanol is not lost as vapour. In practice, ethanol yields observed are 90 to 95% of theoretical.

 

 

  • A number of studies have attempted to accurately predict the sugar to alcohol conversion ratio during wine alcoholic fermentations. However in the absence of a fermentation model that takes all contributing factors into consideration, it has not been possible to declare a reliable sugar to alcohol conversion factor.

  • The generally acceptable approach to estimating potential alcohol is to use the measurement of mass per unit volume (density). However we must not forget that sugar is not the only substance in grape must that contributes to density. Density measures (e.g. hydrometry) are used to approximate the amount of sugar present in grape juice.

  • Using a density measure, during a normal wine yeast alcoholic fermentation, approximately 17g of sugar per litre produces 1% (by volume) of ethanol.

  • The higher the conversion ratio, the lower the alcohol yield

  • The official EEC sugar to alcohol conversion ratio is 16.83g sugar per litre for 1% v/v alcohol

 

Lallemand Investigations:

 

  • Laboratory based investigations, using a standard fermentation environment and 56 wine yeast strains, have shown differences in sugar to alcohol conversions of no more than 0.51% (v/v). These results are consistent with sugar to alcohol conversion ratios between approximately 16.5 to 17.2gm Sugar per litre for 1% v/v Alcohol.

  • Revealed that the sugar to alcohol conversion rate is significantly influenced by the fermentation conditions. With any one yeast strain, the quantity of alcohol and carbon dioxide formed from carbohydrates, as well as the nature and concentration of by-products, vary with fermentation temperature, extent of aeration and Yeast Assimilable Nitrogen (YAN) levels.

  • For example when individual yeast strains were studied under low and high YAN levels, the sugar to alcohol conversion rate was not consistent. For example, some yeast strains had higher conversion rates at the LOW YAN level, while other strains had higher conversion rates at the HIGH YAN level. The Lallemand study concluded that due to the various influencing factors, characterisation of sugar to alcohol conversion rates for wine yeast remains inconclusive. Perhaps the only exception is that non-cerevisiae and non-Saccharomyces yeast DO DIFFER from Saccharomyces cerevisiae strains. The S.cerevisiae strains generally are more efficient at converting sugar to alcohol.

Aromatic Intensity, Complexity, Mouthfeel and Longevity of Wines = a World of Possibilities
26 July, 2011

Level2® TD contains two species of yeast selected for their complementary properties – Torulaspora delbrueckii strain 291 and Saccharomyces cerevisiae strain 734. When used for sequential inoculation, these yeasts encourage aromatic intensity, complexity and mouthfeel in wines, fermentation after fermentation.

1. Aromatic intensity, complexity, mouthfeel and longevity
Numerous trials have been carried out over several years on musts made with different grapes, including chardonnay, sémillon and maccabeu, which were inoculated sequentially with T. delbrueckii 291 and its complementary S. cerevisiae 734 yeast in the Level2® TD kit. Level2® TD confirmed its capacity to reveal a wide range of aromatic esters, including linear or branched fatty acid esters. In particular, two esters, ethyl propionate, and ethyl 2-methyl propionate, are found in the majority of cases to be in higher concentrations in wines fermented with the Level2® TD, compared to a vast array of different selected yeasts. It was shown that the overexpression of those two esters is directly correlated to the action of T.delbrueckii 291, and not the work of S.cerevisiae, or even other T.delbrueckii. On the other hand, isoamyl acetate, did not vary consistently and significantly from one trial to another. This finding is key in explaining the gain in aromatic complexity by the increase in ester production that are responsible for the delicate fruity and floral aromas. Limiting the production of amylic notes (banana, english candy) associated with isoamyl acetate was important since it could overcome the delicate fruity and floral aromas (Figure 1).

Note that the esters revealed by Level2® TD are also those considered the most stables over time, while the acetate esters hydrolyze more quickly during storage (Baumes and Schneider 2009).
Level2® TD sequential fermentation kit contributed to enhance the fruity and pastry aromas in wines as shown in Figure 2. The most interesting effects of the synergy between these yeasts are the aromatic complexity and the intensity of the mouthfeel in the wines from white grape varietals.

26 July, 2011

LALLEMAND OENOLOGY
Since the 1970s, Lallemand has focused its specialty fermentation knowledge on developing high quality active dry yeasts for the worldwide oenology industry. Soon after, the company started developing wine bacteria, fermentation adjuncts and specialty inactivated yeasts. The Lallemand range of oenology products is most widely known under the LALVIN®, UVAFERM® and ENOFERM® brand names. In fact, Lallemand is still the only major supplier of yeast or bacteria that is a primary producer of both.

Lallemand owes its success to its constant pursuit of excellence, flexibility and ongoing investments in research and development. Lallemand offers customers an extremely broad range of high quality products.

PRODUCTION AND QUALITY
Lallemand's ISO 9002 certified wine-yeast production facilities are located in Grenaa, Denmark, and Montréal, Canada. Oenology bacteria are produced in a specially accredited facility in Aurillac, France, and in Montréal. The plant in Vienna, Austria, is dedicated to the production of specialty yeasts. Using processes specific to each strain, the yeast cultures are fermented and undergo high-density concentration and granulation. Yeasts are then fluid bed dried and bacteria are freeze dried. Lallemand products pass 20 rigorous quality tests before leaving the factory, and are traceable for three years after production.

RESEARCH, DEVELOPMENT AND APPLICATIONS
To offer customers the finest possible products, Lallemand places particular importance on R & D.

Research begins internally:

  • A team based in Toulouse, France, conducts fermented beverage- related research in cooperation with oenological institutes throughout the world.
  • Teams based at the Montréal plant and the Biotechnology Research Institute (BRI) in Montréal develop new strains and production procedures, and carry out more fundamental research.

The interface between researchers and professionals:
Research programs, scientific papers and ongoing contacts link Lallemand to the most prestigious microbiology laboratories in Europe, Australia, North America, South America and South
Africa.

Lallemand has an active information policy, which includes:

  • The Entretiens Scientifiques Lallemand. Every year, top microbiology and oenology specialists are brought together to share current research on a particular theme; cooperative technical progress is stimulated through dialogue among these specialists and other professionals drawn from wine-producing countries throughout the world.

Balanced Nutrition for Healthy Alcoholic Fermentation
09 March, 2011

Nitrogen is an essential nutrient for smooth alcoholic fermentation (AF). Numerous studies have shown that nitrogen has a positive impact on the growth and fermentation activity of yeast (Bell et al. 1979, Ough and Lee 1981, Bezenger and Navarro 1987). Deficiencies in yeast-available nitrogen (YAN) in the must significantly increase the risk of sluggish or stuck fermentations because they can arrest protein synthesis in the yeast cells. We consider a must with an initial sugar level of about 200 g/L to be deficient when its YAN concentration is about 150 mg/L (Henschke and Jiranek 1993). A YAN deficiency in the must can also cause the yeast to increase the production of H2S (Henschke and Jiranek 1991). This edition of Winemaking Update focuses on the impact of balanced nutrition on alcoholic fermentation.
