Winemaking Calculators
Free winemaking calculators.
Potential alcohol, sulfite additions, acid adjustments, and more.
Brix to Potential Alcohol Calculator
Convert grape juice Brix (sugar content) to potential alcohol percentage. Essential for winemaking planning and harvest decisions.
Chaptalization Calculator
Calculate how much sugar to add to grape must to increase alcohol content. Converts Brix or specific gravity to target alcohol with sugar addition amounts.
Malolactic Fermentation Temperature Guide
Find the ideal temperature range for malolactic fermentation (MLF) and estimate completion time. Critical for red wine softness and stability.
Sulfite Addition Calculator (Wine SO2)
Calculate potassium metabisulfite (K-Meta) or Campden tablet dose to achieve target free SO2 in wine. Accounts for wine pH for accurate protection.
Wine Acid Adjustment Calculator
Calculate how much tartaric acid to add to raise wine acidity (lower pH). Enter volume, current pH, and target pH for exact dosing.
Wine Bottling Calculator
Calculate how many wine bottles you need for a given volume. Accounts for standard 750 mL, magnums, and half-bottles. Includes label and cork quantities.
Wine Residual Sugar Calculator
Calculate residual sugar (RS) in wine from specific gravity readings. Determine wine sweetness level from grams per liter of residual sugar.
Wine Yield Calculator
Calculate how many bottles of wine you will get from a given weight of grapes. Includes typical yield ratios for red and white wine production.
