A nutrient blend from Wyeast, designed especially for use with wine yeast.
Yeast Nutrient & Additives
With these additives you will have everything you will need to properly treat your wine throughout the various stages of fermentation. Adjust your acid levels prior to fermentation, add a dash of nutrient and sanitize your must before pitching yeast. After fermentation is complete, use some sulfites and potassium sorbate to stabilize the wine prior to adding oak. If your wine needs a bit more backbone and balance you can use some tannins to round it out. Find it all here!
