Gusmer Enterprises Micro Essentials TM Nutrients Support for Healthy Fermentations
Time-Release Nutrients for Yeast Winemakers commonly make incremental additions of nutrients during the first half of the fermentation as a means to manage the fermentation rate through the quantity and composition of available nutrients. The nutrient demand is greatest during the exponential phase, when cells require more organic nitrogen rich compounds to reach the desired level of biomass. This leaves limited nutrients available for subsequent generations of yeast to maintain the biomass through to the end of fermentation. Incremental addition assures nutrient availability to these later generations of yeast. The Micro Essentials Complete-TR and Micro Essentials Boost-TR were developed as a solution to the logistical difficulties of incremental additions. Nutrients are compressed into tablets creating a distinct time-release profile, delivering the proper dose and composition of nutrients as needed throughout the fermentation with a single addition.
Gusmer’s Micro Essentials ™ fermentation nutrients include a complete range of supplements for yeast rehydration, primary fermentation, and malolactic fermentation. Micro Essentials nutrient formulations incorporate findings from the latest research and are based on premium ingredients. Our complex supplements contain highly refined polypeptides and amino acids, and a full spectrum of essential vitamins, minerals and yeast survival factors for a rich source of compounds that are highly assimilable by yeast and bacteria. • Produced domestically in our own facility under GMP conditions, and comply with all TTB regulations • Used to support cell growth, general metabolism, protein synthesis, and alcohol tolerance • Nutrients contribute to healthy fermentations and guard against the formation of hydrogen sulfide and other unwanted metabolites
Customer Testimonial
Micro Essentials Complete-TR • Combination of two tablets, each with a distinct time-release profile and nutrient composition • Both tablets are added together at onset of inoculation • One table contains a higher percentage of organic nitrogen, vitamins, minerals, and yeast survival factors, and has a faster dissolution rate to build biomass during the exponential phase of yeast growth • The other tablet has a higher percentage of inorganic nitrogen and a slower dissolution rate to provide nutrition through the fermentation Micro Essentials Boost-TR • Contains a higher percentage of inorganic nitrogen along with vitamins, minerals, and yeast survival factors • Slower dissolution rate to provide nutrition throughout the fermentation • Used to supplement Micro Essentials Complete-TR in musts that have lower YAN or that are known to be problematic

Dose Rate
Micro Essentials Powder • Full spectrum nutrient blend in powdered form • Dose into the must during inoculation and as required during alcoholic fermentation • Recommended for use in both red and white wine fermentation when juice analysis shows low levels of YAN or when fermentation conditions prove challenging Micro Essentials Prime • Yeast rehydration nutrient that provides assimilable organic nitrogen and micronutrients without DAP • The addition of bioavailable nutrients during yeast fermentation helps to ensure survival during the stressful transition of inoculation • Compared to other yeast rehydration nutrients, Micro Essentials Prime provides healthier and faster fermentation at a lower dose rate Micro Essentials Trace • Pure vitamin and mineral complex • Used to supplement other yeast nutrients when additional micronutrients are required
