Rehydration

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.
