Potassium Bicarbonate, powder, food grade. Used to reduce the acidity of musts or wines. Avoid using if the pH is above 3.5, or if you need to drop the acidity more than about 0.3%. Only about 70% of the acid reduction potential is realized unless you cold stabilize after treating the wine. It increases pH more for a given drop in acidity than calcium carbonate, but can be used closer to bottling time. 3.4 grams per gallon will give a potential 0.1% drop in acidity.
