(NUT410) A special mix of 13 different foods and nutrients. Designed specifically to pre-start any liquid or dried wine yeasts. Pre-starting the yeast allows the fermentation to start much sooner and at a more accelerated pace. It also allows for a sounder, more thorough fermentation. That means less chance of contamination in your wine caused by stalled fermentation. The result is a more stable, cleaner tasting wine that will ferment to its highest alcohol potential. Comes with complete directions.
