Gusmer Enterprises Micro Essentials TM Nutrients
The use of fermentation nutrients in alcoholic fermentations is well documented. In addition to fermentable sugars, yeast require nitrogen (free amino nitrogen), vitamins, minerals, sterols and more in order to build biomass and reach the cell density required for a healthy fermentation. While fruit and grain substrates supply the carbohydrates required for fermentable sugars, they often lack these other key nutritional components. When these key nutritional components are not made available, and yeast grow under stressful conditions, fermentations are often sluggish, inconsistent, incomplete and produce undesirable metabolites such as hydrogen sulfide that can carry over into the distillate. Gusmer’s Micro Essentials fermentation nutrients, designed specifically for alcoholic fermentations, are based on findings from the latest research and incorporate premium ingredients. Our complex supplements contain highly refined polypeptides and amino acids, a full spectrum of essential vitamins, minerals and yeast survival factors for a rich source of compounds that are highly assimilable by yeast. These nutrients are produced locally in our own facility, under GMP conditions. Used to support yeast growth, protein synthesis, general metabolism, and alcohol tolerance, Micro Essentials contribute greatly to vigorous fermentations, consistent congener production and help guard against the formation of unwanted metabolites. Yeast Nutrients for Distillation
“ At Topo Organic Spirits the MicroEssentials Powder has handsomely improved our fermentations through improving yeast health and therefore better quality alcohol with higher yields. As we are certified organic, having access to a Non-GMO yeast nutrient is of great importance. The MicroEssentials Powder is easy to weigh and dose for the various fermentables we use – our organic wheat, molasses and cane juice or fruit juices. Our thanks to Gusmer for their technical support staff and great products. ”

Micro Essentials Powder is a full spectrum nutrient blend in a powdered form, which is dosed into the fermenter during inoculation, and as required throughout the alcoholic fermentation. It is recommended for all fruit and grain based spirits, especially when the FAN (free amino nitrogen) is known to be low or fermentation conditions prove to be challenging. Micro Essentials Complete -TR is a time-release fermentation nutrient. Alcoholic fermentations often require incremental additions of nutrients during the early stages as a means to manage the fermentation. The demand is greatest during the exponential phase of the yeast growth cycle, when the cells require more organic nitrogen-rich compounds to reach the desired level of biomass. Incremental addition assures nutrient availability to these later generations of yeast. Micro Essentials Complete was developed as a solution to the difficulties of incremental additions. Nutrients are compressed into tablets creating a distinct time-release profile, delivering the proper dose and composition as needed – but with a single addition. Both tablets are added together in equal parts at the onset of inoculation. One tablet contains a higher percentage of organically derived nitrogen, along with inorganic nitrogen, vitamins, minerals and yeast survival factors, and has a fast dissolution rate. This tablet provides the nutrients required to build biomass during the exponential phase. The other tablet is formulated with the same ingredients, but has a higher percentage of inorganic nitrogen and a slower dissolution rate. Together, these two tablets provide the right composition of nutrients at the right time.
