Cider ABV Calculator (Estimate)

Estimate a cider’s potential alcohol from its juice specific gravity, using the Prickly Cider factor. An estimate, not an official measurement — see the disclaimer below.

Calculator

Non-regulatory estimate

Enter your juice’s specific gravity to estimate the cider’s potential alcohol if it ferments to dry.

⚠️ This is a reference estimate for cider making — not an official measurement, and never valid for a tax or label filing.

Your starting (original) gravity — most apple juice is around 1.045–1.060.

Enter a juice specific gravity to see the potential alcohol.

Estimate only — the cidermaking potential-alcohol convention ((SG − 1) × 128, pricklycider.com), not an official measurement.

Reference tools, not a system of record. These free calculators are provided for convenience and general reference only. They are not a system of record and must not be used as the basis for any TTB or state compliance filing — even when a result is correct. Your official filings are governed by the applicable measurement and gauging methods and by your own production records.
