Novonesis ML Bacteria - Trusted by more Winemakers | Learn More
Novonesis Viniflora® cultures are the most widely used malolactic cultures. Reliable and predictable, Viniflora bacteria cultures are trusted by more winemakers worldwide to get their wines through malolactic fermentation on time and with desirable organoleptic outcomes.
However, not all strains of Oenococcus oeni are the same, nor are all malolactic bacterial preparations. Some strains are more tolerant to environmental parameters such as pH, temperature, sulfur dioxide and alcohol. To help you choose the right strain for your wine, view the chart below and watch the videos for more tips.

CDR WineLab Webinar: Dealcoholization Techniques and their Effect on the Sensory Profile of Wine
Join us for this complimentary technical webinar on Dealcoholization Techniques and their Effect on the Sensory Profile of Wine.
Tuesday, Jun 3, 2025 9:00 AM - 10:15 AM PST
Non-alcoholic wine is gaining popularity as a healthier alternative to traditional wine, with growing consumer interest in low- and no-alcohol beverages. Key market trends include the health and wellness movement, product innovation, societal shifts, evolving regulations, and changing Millennial and Gen Z preferences. This webinar will cover various dealcoholizing techniques: viticultural methods, physical processes, membrane technologies, and enzymatic and microbiological approaches. Sensory attributes like taste and aroma significantly impact consumer acceptance. We'll explore how dealcoholization affects wine's sensory profile and present strategies for optimizing alcohol-free wines.

Are Winemakers Getting the Most from Their Yeast?
The nutritional health of yeast can determine the success – or failure - of the resulting wine. To get the most out of your yeast, a high-quality nutrient product is essential.
“High quality micronutrients are essential to the healthy development of the yeast and a robust fermentation,” emphasizes Bill Merz, Gusmer Enterprises Inc’s Director of West Coast Beverage Sales and a winemaker himself. “The solubility of those nutrients is also key to yeast cell access. That’s exactly the kind of scientific research Gusmer has done and the superior products it provides.”
Gusmer Enterprises, Inc., a leading manufacturer and supplier of fermentation and filtration products for the beverage, food and pharmaceutical industries since 1924, specializes in the distribution of yeast nutrition developed to ensure healthy, vigorous and clean wine batch fermentation, vintage after vintage.
Included in Gusmer ‘s comprehensive portfolio of nutritional yeast enhancements to assist winemakers with their craft is MicroEssentials Complete-TR, the most advanced yeast nutrient on the market, incorporating the latest research in yeast nutrition and time-release technology.
MicroEssentials Complete-TR’s unique, sustained-release system is comprised of two tablets, providing complete supplementation while also stimulating incremental dosing.
The first tablet contains a higher percentage of organic nitrogen, as well as inorganic nitrogen, vitamins and minerals to facilitate biomass buildup during the exponential phase of fermentation. The second tablet is formulated to dissolve at a slower rate, and contains a higher concentration of inorganic nitrogen with nutrients to help maintain yeast populations.
Gusmer also offers MicroEssentials Boost, a time-released nutrient specifically designed to supplement ferments with one single dose, making it ideal for barrel fermentation.
In addition, Gusmer offers winemakers MicroEssentials Powder, a full spectrum yeast nutrient blend in a loose powdered form containing highly refined polypeptides, amino acids and a full complement of vitamins, minerals and yeast survival factors that are highly assimilable by yeast.
Gusmer’s MicroEssentials Prime is a DAP-free rehydration nutrient that provides a rich mixture of nitrogen, vitamins and trace minerals. MicroEssentials Prime is designed for multiple applications and is intended for use in conjunction with Gusmer’s other MicroEssentials nutrients.
“Gusmer’s R&D team develops our nutrient products in-house, ensuring that we understand their performance firsthand," notes Chris Nevosh, Gusmer’s Senior Product Manager. “We collaborate closely with our customers, conducting extensive yeast and nutrient trials to guarantee the highest quality products and successful results. What sets Gusmer apart is our Service with Knowledge® approach, supported by a dedicated team of application specialists, R&D scientists, and technical sales representatives, all available to help you achieve your goals.”
Gusmer is proud to be a US manufacturer, with 3 manufacturing facilities, and warehousing strategically located across the country. In addition, Gusmer’s Napa and Sonoma County locations offer retail and analytical services. Our Gusmer team is ready to support, collaborate and innovate with you.

To achieve the best process economics an efficient winery must operate on a Total Cost of Filtration basis. This recognizes that superior filter performance will yield better economics over time. Filter cost must consider total gallons throughput per change-out. A Total Cost of Filtration approach also realizes that factors influenced by filter performance are often more costly than the filters themselves. The following resources below will help you to optimize your process:
- FC 01 Cartridge Cleaning Sanitization & Storage Wine
