Arauner Kitzinger Tartaric Acid L(+) E334, 1 kg for Acidifying Must

Tartaric acid is the acid that occurs naturally in the grape. As L(+) tartaric acid (E334), it can be used in a targeted way to raise the acidity of grape must and wine when the batch brings too little acid of its own.

This tartaric acid is highly pure and comes in a 1 kg bag. The pack still gives the old limits of 2.5 g/l for wine and 1.5 g/l for grape must. Since December 2021, grapes, must, new wine and wine may be acidified by up to 4 g/l, expressed as tartaric acid (Regulation (EU) 2021/2117); at home it is best to stay at no more than 3 g of pure acid per litre. Measure the acidity beforehand, then you dose precisely and don't over-correct past your target.
