How much honey do you need for mead?
Honey is mostly sugar, and each pound dissolved in one US gallon of water raises the specific gravity by about 35 points (0.035). The calculator uses that figure to turn your target into a honey weight:
Honey (lb) = (target gravity − 1) × 1000 × gallons ÷ 35

Honey sugar content varies with water content and floral source, so treat the result as a starting point. Mix the honey in fully, take a hydrometer reading, and add more honey or water to hit your number.
Measuring your mead's alcohol
Take a gravity reading before you pitch the yeast, and another once the reading has held steady for several days. Enter both in the Mead ABV tab. Meads are usually stronger than beer, so the calculator defaults to the alternate equation, which is more accurate above about 7% ABV than the standard (OG − FG) × 131.25 formula.
If fermentation stops well above 1.010 and you wanted a dry mead, it may be stuck. Common causes are too little yeast nutrient, a cold fermentation or a starting gravity above your yeast's alcohol tolerance. Many mead makers split their yeast nutrient into several additions (staggered nutrient additions) over the first week to prevent this.

Method and sources
- Alternate equation: ABV = 76.08 × (OG − FG) / (1.775 − OG) × FG / 0.794. This is Michael Hall's published equation for alcohol by weight, converted to alcohol by volume by multiplying by FG / 0.794 (0.794 is the specific gravity of pure ethanol).
- Standard equation: ABV = (OG − FG) × 131.25. This is the straight-line shortcut most homebrew software uses. The two equations agree closely for normal-strength beer and drift apart as the starting gravity rises.
- Brix and Plato: converted from gravity with a standard brewing polynomial. We checked it against the reference polynomial below, and the two agree within 0.1 °Bx between 1.000 and 1.140.
- Sugar additions: each fermentable is counted in gravity points per pound per US gallon. Honey is 35, a working average, since honey's moisture varies and some mead makers use figures up to 42.
- Honey for a target strength: the calculator solves the alternate equation backwards for the starting gravity that reaches your target, assuming the mead finishes dry, then converts the gravity points into honey.
Every gravity-based ABV is an estimate. A lab measures alcohol directly, and its result can differ slightly from any hydrometer formula.

Frequently asked questions
How much honey do I need per gallon of mead?
Honey adds about 35 gravity points per pound per gallon. Roughly 2 lb per gallon makes a light session mead (about 1.070), 3 lb makes a standard mead (about 1.105) and 4 lb or more makes a sweet or dessert mead.
What is a good starting gravity for mead?
Hydromels start around 1.035 to 1.060, standard meads around 1.080 to 1.120, and sack (dessert) meads at 1.120 or higher.
How do I calculate the ABV of mead?
Measure the gravity before pitching the yeast and again when fermentation is finished. Because most meads are stronger than beer, use the alternate equation, which this calculator selects by default.
