About this calculator

How-to: take a specific-gravity reading before fermentation (OG) and again when fully fermented (FG). ABV% ≈ (OG − FG) × 131.25 for beer/cider; for wine use ((OG − FG) × 1000) / 7.36. To raise potential ABV, add sucrose at ~17 g/L per 1% ABV (yields ~1.006 SG increase per 15 g/L). Priming sugar for bottle conditioning: 6–8 g/L for ales, 8–10 g/L for lagers, 20–24 g/L for sparkling wine/cider (méthode traditionnelle).

Frequently asked questions

Which formula is more accurate?

The × 131.25 rule is fine below 6% ABV. For strong beers/wines use the Balling / cubic ABV formula, or take gravity readings with a refractometer corrected for alcohol.

Can I use honey or DME instead of sucrose?

Yes. Honey ≈ 82% fermentable sugar, so scale by 1.22×. Dry malt extract (DME) ≈ 75% fermentable, scale by 1.33×.

Is bottle conditioning legal for commercial sale?

Yes, but declare 'contains sediment' and use bottles rated for the target CO₂ volume. Sparkling wine bottles handle 6+ atmospheres; beer bottles top out around 4.

What does the Brewing & Winemaking ABV + Sugar Adjustment Calculator do?

ABV from hydrometer readings (OG / FG) with the sugar addition needed to hit a target ABV — works for beer, wine, cider and mead. How-to: take a specific-gravity reading before fermentation (OG) and again when fully fermented (FG). ABV% ≈ (OG − FG) × 131.25 for beer/cider; for wine use ((OG − FG) × 1000) / 7.36. To raise potential ABV, add sucrose at ~17 g/L per 1% ABV (yields ~1.006 SG increase per 15 g/L). Priming sugar for bottle conditioning: 6–8 g/L for ales, 8–10 g/L for lagers, 20–24 g/L for sparkling wine/cider (méthode traditionnelle).
