Acid Blend is a coarse mixture of three common fruit acids: citric acid, malic acid, and tartaric acid. It is added directly to wine or must to increase its acidity when needed. The blend provides a balanced and rounded flavour profile to the wine, which is essential for its taste and overall balance.
 
1 teaspoon of acid blend will increase the acidity of wine by approximately 0.1 grams per liter. The amount of acid that is needed will vary depending on the type of wine and the desired acidity level.
