(TAN210) Also known as tannic acid, this tannin is very light in color. It is preferred by most winemakers to be added to their white and rose wines. Tannins plays three distinctive roles in wine. The first is flavor. Tannins increase the zesty flavors that is often lacking in many home wines. Quite literally tannin is the "zest" or peel of the grape. Tannins aid in the clarification process. Residual proteins and other particles are neutralized by its presence. Tannins also aid in the aging and keeping qualities of the wine. Wines deficient in tannin tend to not take advantage of the aging process. Their improvement with time is only marginal. These wines also tend to deteriorate in quality more rapidly in longer storage situations. Comes complete with directions.
