Liquid. Recommended to increase the acidity of wines and beers. Also suitable for wine which has finished fermenting.
Dosage: 12,5 ml (= 15 g) / 10 l increases the acidity with 1 g/l.
The acidity of must/wine is always expressed in grams of tartaric acid/litre. In French books, you will find the acidity expressed in sulphuric acid ÷ 1.53. Acidity as tartaric acid = acidity as sulphuric acid x 1.53.
