A smooth, complete fermentation doesn’t happen by chance, it starts with balanced yeast nutrition. When yeast has access to the right nutrients at the right time, you avoid sluggish or stuck fermentations, reduce the risk of Hâ‚‚S and VA, and unlock the full aromatic potential of your grapes.  Why Yeast Nutrition Matters? Nitrogen is the main driver of yeast growth and fermentation activity. Saccharomyces can assimilate only ammonium ions (DAP), amino acids (organic nitrogen), and small peptides (organic nitrogen). Amino acids are strategic: they are taken up early, stored, and used gradually. Some of them also act as aroma precursors (thiols, esters, acetates). Vitamins & minerals (thiamine, Mg, Zn) act as cofactors in enzymatic reactions and have a role in cell growth, fermentation activity, and nitrogen metabolism. Sterols & long-chain fatty acids are essential for membrane structure, stress resistance, and survival. Click here for all fermentation tips & gui

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 nutritio

Why Yeast-Based Nutrients are Better than DAP: Organic vs. Inorganic Nitrogen Learn why organic yeast nutrition is an important part of wine quality wine production and helps to ensure reliable fermentation.  What's the Difference? Diammonium Phosphate (DAP) Inorganic Nitrogen Inorganic nitrogen is supplied as ammonia (NH3). The most common winemaking source is diammonium phosphate (DAP), which can be found as a standalone nutrient or can be part of a blended nutrient (DAP with inactivated yeast). Yeast-Based Nutrients Organic Nitrogen Organic nitrogen is supplied as amino acids. Common winemaking sources are nutrients derived from autolyzed yeast. These nutrients supply up to 19 different amino acids as well as naturally occuring vitamins and minerals from yeast. Why Choose Yeast-Based Nutrients Although yeast like DAP, it is akin to junk food. Yeast use it quickly and have a metabolic response much like a "sugar rush." Yeast based nutrients are more like a bala

Activated Sludge: A brownish flocculent of bacterial organisms developed in aeration tanks. Activated Sludge Process: Method of eliminating pollution in wastewater. Oxygen is released into tanks containing dissolved organic substances. Bacteria in the tanks break down the organic pollutants. Water is then separated from the activated sludge and discharged. Most of the sludge is reused in the treatment process; the remainder is disposed of per local wastewater regulations. Aeration: Process of bringing air into contact with a liquid. It can be developed using natural wind on a pond or by injecting air into an aeration tank. Aerobic Bacteria: Bacteria that require free oxygen for growth. Aerobic Wastewater Treatment: It uses bacteria to break down waste; the bacteria require the presence of oxygen to live and thrive. Anaerobic Bacteria: Bacteria that grow without the presence of free oxygen; it derives oxygen from breaking down waste Anaerobic Wastewater Treatment: Uses bacteria to brea

Understanding the nutritional requirements of yeast is fundamental to accomplishing successful fermentations and preventing stuck fermentations. Managing yeast nutrition allows for regular and complete fermentations, as well as minimizing off-aromas and enhancing sensory qualities.    WHAT ARE YEAST NUTRITIONAL NEEDS?  Nitrogen is one of the most important nutritional factor for yeast. It is mostly used to synthesize proteins: structural proteins, necessary to create new cells; enzymes, necessary for the metabolic processes, including the conversion of sugar into alcohol, transport proteins located in the cell membrane. Saccharomyces cerevisiae can only assimilate nitrogen in the form of ammonium, amino acids, and small peptides.  Ammonium, easy to pass through the cell membrane, is the first and quickest component to be assimilated by yeast. It is used right away by the yeast.  Amino acids require more energy from yeast to be assimilated. As alcohol inhibit t
