Accordingly, wine producers throughout the world have increased their focus on two key areas when it comes to wine:
Irrespective of the type of wine: classical 'terroir type' or modern 'varietal type', fermentation management is key to transforming the potential wine coming from the grapes into the best and safest wine possible.
To achieve these natural transformations in optimal conditions, Chr. Hansen has developed a range of natural solutions to assist winemakers and marketing managers in:
This toolbox for winemakers is named Viniflora® and contains different types of innovative yeasts, bacteria, nutrients and enzymes all carefully selected to bring wine producers the very best from Nature.
Viniflora® Concerto™ is a pure strain of Lachancea thermotolerans to be used in combination with your Saccharomyces cerevisiae strain of choice. This non-Saccharomyces yeast strain has been carefully selected to mimic successful wild ferments, increase aromatic complexity, enhance fresh fruit forward wines, and develop a round mouthfeel. This is particularly recommended for white and red wines from warmer climates.
This specialty yeast is not intended to achieve complete alcoholic fermentation but to enhance wine complexity. Concerto has to be followed by a Saccharomyces cerevisiae yeast of choice to achieve a safe and fast alcoholic fermentation.

How speeding up the MLF process helps protect sensory qualities, reduce costs and get wines ready earlier.
Time is money, also true in winemaking
The primary cluster of benefits from improving the speed of malolactic fermentation are financial and managerial:
An example of this is given in the diagram below for a 2008 Spanish Tempranillo.
Alcoholic fermentation was nearly finished when the VINIFLORA® malolactic bacteria were inoculated into the must for the two co-inoculation modalities (green and yellow in the graph). The red curve corresponds to a wine that went through spontaneous fermentation with wild bacteria that were moved from a tank in fermentation and inoculated as a control (cross-seeding with wild unidentified flora).
The timing difference between these two modalities inoculated with VINIFLORA® or by spontaneous fermentation is 23 days!
Wines inoculated with VINIFLORA® were microbiologically stabilized more than 3 weeks earlier than the spontaneous ferment and were ready to enter into their maturation phase, to be filtered and bottled, or tasted by journalists and traders; definitively a great competitive advantage.
VINIFLORA® malolactic cultures not only bring speed to the malolactic fermentation process but also consistency and reliability through natural, selected strains of Oenococcus oeni and Lactobacillus plantarum bacteria.
Three main axes are available to manage MLF speed: the strain selected, MLF temperature and the timing of bacteria inoculation compared to yeast inoculation: early co-inoculation, late co-inoculation or sequential inoculation.
We have a Wine Team available all around the world to bring assistance and help calculate the savings made by using VINIFLORA® through our value calculator: VINISAVE.
Lower histamine - Historically, the primary reason to use VINIFLORA® oenological bacteria from Chr. Hansen was to ensure a minimal production of histamine in the final wine.
When we launched the first VINIFLORA® freeze-dried products ready for direct inoculation in wine, our first customers were some of the most famous, sometimes iconic, wineries producing red wines in Europe and USA that applied a famous principle: “If we can make it safer for our customers, we have to do it’’.
And indeed, wines are safer when using VINIFLORA® oenological cultures, as we have selected strains from nature that are not able to produce histamine, putrescine and some other biogenic amines during malolactic fermentation. Spontaneous, wild bacteria may have the ability to produce a high concentration of biogenic amines, particularly histamine, putrescine and cadaverine during malolactic fermentation. Chr. Hansen’s team of experts know how to avoid this.
Today, our expertise in minimizing the production of histamine is renown worldwide, and we have helped several wine companies around the world to perfectly define their fermentation program to avoid the production of histamine, to name but one amine.
This technical expertise now satisfies consumer demand in some part of the world, such as northern Europe. Ever more consumers are aware about the impact of histamine when they consume a moderate amount of wine. Red-face Syndrome and sometimes minor headaches are examples of symptoms associated with the presence of biogenic amines, and the alcohol contained in a glass of wine can enhance the absorption and the impact of histamine even at low concentration.
Developing wines that do not contain biogenic amines and, reduce the histamine level to the minimum in particular, is one of the niche markets the large category of red wines where Chr. Hansen is heavily involved, improving food and health.
Natural Solutions for Malolactic Fermentations and Bio-Protection.
Oenological bacteria
With our broad knowledge regarding lactic acid bacteria and fermentation management, we have created a range of malolactic bacteria covering all types of winemaking applications and bringing to winemakers the best strains of Oenococcus oeni and Lactobacillus plantarum for their wines.
Our approach is quite simple: grapes production and alcoholic fermentations are currently well managed and controlled by viticulturists and then by winemakers. However there is a lack of focus on malolactic fermentation management, destroying an important part of the good work previously done!
The Viniflora® bacteria range is made up of several strains selected to cover the main needs identified through our constant dialogue with winemakers but also in assessing consumers’ current and future demands.
Sophisticated flavor profiles to reflect wines diversity
Viniflora® strains can help modulate the amount of diacetyl (buttery, creamy flavors) produced during malolactic fermentation, from no production (with CiNe™) to the highest possible conversion rate with CH35, giving wines an additional layer of complexity.
Winemakers can also select the strain to use in relation to the final flavor profile they expect, for instance by improving fruit flavor intensity with NoVA™, CiNe™, CH16 or Oenos 2.0 in red, rosé or white wines. This flavor intensity modulation is a natural process where selected strains of bacteria show their ability -or absence of ability- to convert some types of flavor precursors that are already present in the wine.
Efficient solutions to lower a wine’s final sulfur content and get more authentic wines
The CiNe™ strain is now widely used in white and rosé wines to manage malolactic fermentation without impacting the flavor profile of the wine. Winemakers can now achieve this secondary fermentation in wines that traditionally do not go through malolactic fermentation: rosé wines or fruit-forward white wines from aromatic grape varieties: Sauvignon Blanc, Riesling or Viognier.
The primary consequence is a wine stabilized through a microbial solution instead of being stabilized by sulfites that are classically used to kill microorganisms and avoid the development of unwanted bacteria.
Highly concentrated products to maximize bio-protective effects and ensure a smooth fermentation
Chr. Hansen brings winemakers some powerful tools to control their malolactic fermentations through a range of high-quality bacteria products ready for direct inoculation: the 'DVS®' technology. The different Viniflora® strains are able to cover a large spectrum of wine applications: from difficult base wines for sparkling wines coming from cool or cold areas to high-alcohol wines produced in extremely hot climates. In all cases, managing MLF speed is a key success factor. In some cases, wineries seek the fastest solutions possible, and that is when CH11, Oenos 2.0, CH16 or NoVA™ become very good options to answer this ‘need for speed.’ In some other cases, a slowdown may be needed, making CH35 and CiNe™ the ideal strains to select
Our proactive approach with bio-protective cultures helps reducing sulfite content
Consumer demand is evolving rapidly within the wine industry. The megatrend about ‘natural and pure’ products is also affecting wine demand. Consumers want winemakers to minimize the use of exogeneous products, such as preservatives.
This is clearly leading a worldwide trend within the wine industry for lower sulfite content and even the development of no-sulfite wine ranges.
Replacing sulfites whenever possible:
The secret to success in making good yet non-sulfited wines is to clearly assess why sulfites are used during the winemaking process and replace this activity with natural solutions.
Consumer demand crossed with new technical knowledge leads to one main aim: no more sulfites in winemaking.
Chr. Hansen has been a participant in the quest to replace sulfites in wines since the very beginning. Today, the influential book How to make great wines without sulfites? states it very firmly: to fight against the development of undesired microorganisms, the best way is to use well-know, safe and highly concentrated microbial solutions from the Viniflora® range developed by Chr. Hansen.
In red wines, the use of Viniflora® protective cultures helps develop wines made without sulfites and those that use 5–15 ppm sulfites only at the very end of the process during bottling. The absence of sulfites until then makes this final addition extremely active against the growth of spoilage organisms.
Chr. Hansen's cultures for bio-protection
Our range of specialty yeast products helps contain the development of unwanted yeasts during pre-alcoholic fermentation phases such as cold soak, pre-fermentation maceration. Our strain of Torulaspora delbrueckii performs particularly well in these conditions.
Within our range of oenological bacteria, our new Lactobacillus plantarum (NoVA™), which helps suppress Acetobacter and molds, our Oenococcus oeni strains CH16 or CH35, which fights against the development of Brettanomyces in red wines during maturation, and CiNe™ are fantastic innovations to lower the level of total sulfites when producing wines.

These two categories of products, despite both representing lower-alcohol alternatives, are radically different.
On one hand, consumer demand is focused on a limited, alcohol reduction that would bring the level of alcohol to a maximum value between 11 and 13% without affecting the wine’s sensorial properties. Technically, it involves removing alcohol or not producing the same amount of alcohol per liter of wine, which is not an easy task if one aims at retaining the same organolepic qualities.
The second category requires more ‘product development’ to get an ideal, final wine with a balanced flavor, no residual sugar, enough body to be easily identified by consumers as being a wine, yet with a low level of alcohol from the very beginning, i.e., even at the time the grapes were harvested and crushed.
Viniflora® specialty yeasts and bacteria can help develop wines in both these product categories. Picking the grapes earlier in the season, when they have a lower level of sugars, is an excellent way of reducing alcohol content in wines. Chr. Hansen’s expertise in fermentation management can help in designing global solutions for lower alcohol yet full-of-taste products!
To deliver wines enjoyable all around the world, winemakers and wineries now have to focus their attention on fermentation management
We are proud to announce the reception of an Innovation + Quality Award for our Viniflora® CONCERTO™, a specialty yeast to kick-start the alcoholic fermentation
The award was handed out at the 2016 edition of Innovation + Quality (IQ) held in Napa Valley, California; an annual forum for ultra-premium wineries focused on cutting-edge innovations that advance wine quality.
“We are proud to be receiving this accolade from an organization of the top high end wine producers in the US, which is an important market for us.
Award candidates were hand selected solely on criteria of innovation that lends itself to high-quality, ultra-premium winemaking, focusing on products that they believe are the best of the best. This honor will undoubtedly strengthen our market position and image as a reliable and innovative partner to the global wine industry,” says Dr Hentie Swiegers, Head of Chr. Hansen’s Wine Innovation department.

Peter, on the advisory board for the IQ Award, was impressed that our award winning yeast, Concerto™, had the ability to produce lactic acid from sugars and thereby help reduce alcohol levels naturally.
A microbial solution to defeat global warming impact on wines
The award winning product Viniflora® CONCERTO™ was launched a few years ago and is a natural alternative to push away uniformity and bring complexity to the wine.
The special strain of yeast partially converts the sugars present in the must into lactic acid, which increases the acidity in the wine and moderately reduces the alcohol/ethanol level. This meets increasing consumer demand for rounder, easier-to-drink wines with lower alcohol by volume (ABV), centered around 12-13%.
It also offsets the impact that increasing temperatures have on the grapes, causing dull, low acid, high alcohol and qualitatively less drinkable wine. Concerto™ is a natural weapon to give freshness and balance to heavy powerful wines from warm climate regions such as California, Australia and the Mediterranean countries.
In North America Viniflora® Concerto™ is available exclusively at Gusmer Enterprises Inc. who also markets other Chr. Hansen strongholds in the Viniflora® portfolio of yeasts and bacteria for winemaking.
Only in 2014 Chr. Hansen received a Frost & Sullivan “Global Award for New Product Innovation Leadership” for its proven track record in pioneering innovation for the wine industry and ensuring consumers high quality, safe and diverse wines.

Chr. Hansen in new EU-funded project to characterize the community of microorganisms that lies at the heart of wine production
A new four-year project has received a grant of € 4 mill. from the Marie Skłodowska-Curie Actions European Training Network within the EU Framework Program for Research and Innovation.
In the project an international collaboration of scientists from a wide range of universities, research institutions, vineyards and private companies aims to characterize the community of microorganisms that lies at the heart of wine production. An improved understanding of the wine microbiome (exploring the relation between terroir and grape micro flora) will have significant effects on the wine industry.
Potential commercialization
“Chr. Hansen is the major industrial partner in this grant and the only one specializing in microbial solutions. One of the outcomes of this study might be the identification of microorganisms with novel application in the wine industry which can potentially be commercialized in future,” says Dr. Hentie Swiegers from Chr. Hansen’s Wine Innovation department.
Dr Swiegers moreover holds a seat on the executive committee of the project, which is led by Professor Lars Hestbjerg Hansen of the Department of Environmental Sciences at Aarhus University, DK.
Chr. Hansen’s role in the project will be to host training sessions for the 15 PhD students from six countries that are studying the vine (grapes) and wine microbiome to characterize it, thereby eventually providing science-based knowledge that can help winemakers control the processes optimally.
“We take pride in being a partner in this project. Not only does it give us a sharp competitive edge in the industry, it is also a blue stamp of our high scientific profile,” notes Dr Swiegers.
Chr. Hansen is a leading global supplier of wine ingredients. Only last September the company was presented with the 2014 Frost & Sullivan Global Award for New Product Innovation Leadership in wine ingredients. The prestigious award was a recognition of Chr. Hansen’s recent product and technology launches that represent landmarks in enology.

A brand new range of Viniflora® products is now available to red wine producers reversing the classical scheme of fermentation management in wines.
Production of red wine requires two fermentation steps during the winemaking process: The alcoholic fermentation where yeasts transform sugars into ethanol and some flavors, traditionally followed by the malolactic fermentation where lactic acid bacteria transform malic acid into lactic acid and a second layer of fermentation related flavors.
“Our approach with Viniflora® NoVA™ is totally opposite; what we now offer to winemakers is to manage their malolactic fermentation in the grape juice before the alcoholic fermentation: A complete change of paradigm,” explains Laurent Hubert, Marketing Director, Wine & Fermented beverages, Chr. Hansen.
Benefits for winemakers: Dramatically reduced fermentation time and risk of spoilage
When the malolactic fermentation happens in grape juice instead of wine the time of this fermentation phase is considerably decreased. Typically with NoVA™, malolactic fermentation is managed in 1 to 3 days as opposed to 3 to 12 weeks today. The wines go through malolactic and alcoholic fermentation within 10 days and are then microbiologically stable.
In warm climate regions, red wines are frequently spoiled by indigenous flora from different molds, yeasts and bacteria species that bring a high frequency of downgrades to the final wine affecting its quality compared to its initial potential, e.g. off-flavors or acetic acid (volatile acidity) produced from the grape juice sugars.
“Speed is absolutely crucial in warm climate environments in order to bio-protect the grape juice and the wines from potential contaminants. This helps in preserving and expressing the flavor precursors from the grape resulting in a fruit forward wine with a higher flavor intensity and complexity,” states Dr. Hentie Swiegers from Chr. Hansen’s Wine Innovation department and in charge of this development project.
Benefits for consumers: Improved wine quality and less sulfites
“Through this new approach, we will help a lot of wineries around the world to limit quality downgrades happening between grape harvesting and alcoholic fermentation or between alcoholic fermentation and malolactic fermentation. The outcome is higher wine quality or more volume of high quality wines from the same amount of grapes.
Ultimately it helps in producing red or rosé wines with far less sulfites (preservatives) and this responds well to consumer’s wishes for healthier and more ‘natural’, clean label products,” concludes Hubert.
NoVA™ is launched in France, Spain, Portugal, Italy and Bulgaria for the 2014 vintage after which it will be available worldwide. Red wine production is around 1.1 billion liters per year.

Among the major global trends within the wine industry, Chr. Hansen idendifies a growing demand from wine consumers for fresher, easier, closer to the initial fruit.
This is particularly true in North America where a wave of 'unoaked' wines (sometimes mentioned as 'naked wines') has reached the shelves and the tables since the beginning of this decade...
To answer that need Chr. Hansen recently launched a new concept named 'Optimize Fruit Expression through fermentations' that works both in white, rosé and red wines gathering together our two most innovative products in a very effective combo:
1- the non-Saccharomyces yeast product 'FrootZen' - to use in grape juices as a prefermentation product before winemakers´ classical yeast product;
2- the malolactic culture 'CiNe' - to achieve your malolactic fermentation without producing a single molecule of diacetyl (typical creamy/dairy like flavour) keeping all the freshness of your initial wine while you increase mouthfeel (natural lactic acid production) and you stabilise the wine through an elegant, natural way.
Wineries around the world have now a solution to optimize fruit expression in their wines and this creates new opportunities for winemakers and marketing managers!
