Potassium Bicarbonate – 2 oz or 1 lb | Brewing pH & Acidity Adjustment

Raise pH and Reduce Excess Acidity in Mead, Wine, and Cider

Potassium Bicarbonate is a versatile buffering agent used by brewers, winemakers, and mead makers to increase pH and help reduce overly sharp acidity. It’s commonly used when a must, juice, or finished beverage tastes too tart, or when you need to fine-tune pH for better balance and stability.

At SoCal Brewing Supply, we carry Potassium Bicarbonate in both 2 oz and 1 lb sizes—perfect for small adjustments or keeping a bulk supply on hand for frequent batches.
