Winemaking Calculators

Free winemaking calculators: potential alcohol content, sulfite additions, acid adjustments, Brix to ABV conversion, and blending tools.

Wine Aging Peak Window Calculator

Estimate when a wine peaks based on tannin level, acid, alcohol, and varietal. Get an aging window from bottle to peak quality and decline curve.

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 Blending Calculator

Calculate the blend ratio of two wines to hit a target Brix or total acidity. Enter the properties of each wine and your desired blend target.

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.
