During yeast manufacture, special processs are employed to promote very high leveles of the natural compound – Trehalose within the yeast.
Trehalose is a natural sugar produced within the yeast cells to protect itself during prolonged storage and stress conditions.
The very high levels of trehalose acheieved also remove the need for re-hydration before adding to must or wort – there is now no advantage in doing this even for high alcohol wines.
Diammonium Phosphate, powder for use in winemaking. This is the basic nitrogen source in nearly all wine yeast nutrients. It can be used by itself or to augment some of the more expensive complete nutrients. At certain stages of fermentation it will help inhibit formation of reduced sulfur compounds.
