Yeast extract T-154 (Tastone 154) is used in many microbiological media recipes because of its rich nutrition, and for the same reason it is also perfect for yeast and ML fermentation in wine.
T154 is a full autolysate high in amino acids in proportions used by yeasts. It also supplies natural vitamins, micronutrients, and other yeast components in an easily soluble form, so nutrients are available instantly to yeasts.
Yeast Extract is one key to Superfood’s great success. T154 is produced to minimize sensory qualities, so it does not give off-flavors to the wine.
