STIMULA™ nutrients go beyond yeast assimilable nitrogen (YAN). These innovative nutrients stimulate specific yeast metabolic pathways involved in aroma production. During fermentation, STIMULA™ nutrients supply additional amino acids, peptides, and specific vitamins and minerals that are crucial for the yeast’s secondary metabolism, boosting the production and/or release of key aromatic compounds like esters, thiols, and terpenes. Yeast produce esters as a natural byproduct of alcohol fermentation. STIMULA CHARDONNAY and STIMULA CABERNET are specifically formulated with the right nutrients to maximize ester production.  Some yeast produce enzymes that convert odorless varietal aroma compounds into their odor active forms. STIMULA SAUVIGNON BLANC, SYRAH, and PINOT NOIR provide yeast with key micronutrients needed to maximize production of those enzymes. LEARN MORE

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

Mastering Yeast Nutrition  How to Make a Fermentation Nutrition Plan Proper yeast nutrition during fermentation is key to preventing sluggish/stuck fermentations, preventing off-odors, and maximizing aroma. Scott Laboratories has always recommended making three nutrient additions at specific time points and our fermentation nutrition planner helps determine the right nutrient and dosage for each stage. READ GUIDE When to add Nutrients and Why Yeast Rehydration This nutrient addition helps get yeast into "first gear," supplying necessary vitamins and minerals required to adapt to the new environment and begin growth.  2-3°Brix Drop This nutrient addition "steps on the gas pedal." It helps yeast multiply during their growth phase and reach the maximum cell count that will finish fermentation.  1/3 Sugar Depletion At this stage, yeast have reached their maximum cell count. This nutrient "tops up the gas tank" and helps yeast sustain and com
