Tartaric Acid - 100g
An essential Ingreadient for elderflower champagne
Tartaric acid may be most immediately recognizable to wine drinkers as the source of wine diamonds, the small potassium bitartrate crystals that sometimes form spontaneously on the cork. These tartrates are harmless, despite sometimes being mistaken for broken glass, and are prevented in many wines through
cold stabilization. The tartrates that remain on the inside of aging barrels were at one time a major industrial source of potassium bitartrate.
However, tartaric acid plays an important role chemically, lowering the pH of fermenting must to a level where many undesirable spoilage bacteria cannot live, and acting as a preservative after fermentation. In the mouth, tartaric acid provides some of the tartness in the wine, although citric and malic acids also play a role.
