* Selling Unit: 1 * Wine Tannin is a crucial component in wine-making, as it contributes to the wine's bitterness and astringency while also adding complexity to the flavour. This product, available in 2.84 grams per 3.78 litres or a 1/2 teaspoon per gallon option, is derived from the grape peel and seeds and acts as a clarifier. It neutralizes residual proteins and particles and helps enhance the aging qualities of wine, which become more complex over time. Although the effects of wine tannin may improve slightly over time, they will ultimately deteriorate, making it essential in producing robust red wines that age for years, even decades. * Product of United States
