Home winemaking requires acid adjustment to find the perfect balance of tart and smooth aspects.E.C. Kraus offers a variety of acid adjustment ingredients within our wine ingredients selection to help you achieve that balance. We have the ingredients to increase or decrease the acidity depending on your needs. Our acid reducing crystals and calcium carbonate calm burning from acidic wines and counteract sour notes, while our tartaric acid adds more acidity to ones that require more.
