How it works
Honey is mostly fermentable sugar, so the amount you need follows from the gravity you want. This tool takes your target ABV and expected final gravity, finds the starting gravity with OG = FG + ABV ÷ 131.25 (the standard homebrew ABV formula, ABV = (OG − FG) × 131.25), then converts gravity points to honey weight using 36 points per pound per gallon. That figure comes from GotMead’s Mead Calculator, which uses 7.2 gravity points per pound of honey in 5 US gallons. Honey varies, so it is an editable field.
Worked example. One US gallon, 14% ABV, finishing at 1.010: OG = 1.010 + 14 ÷ 131.25 = 1.117. That is 116.7 gravity points, and 116.7 ÷ 36 = 3.24 lb of honey (1.47 kg, 51.9 oz). GotMead’s Newbee Guide gives a rougher rule of 3 oz of honey per gallon for each 1% ABV, plus honey for the sugar you want left over, which works out to 45.9 oz here. The rule is a quick guide, so treat the calculated weight as the better starting point and confirm with a hydrometer.
Enter the final batch volume, not the water volume, because honey adds volume. A second check: for a 1.100 must in 5 gallons the tool gives 13.89 lb, or 2.78 lb per gallon, close to the 2 lb 11.7 oz per gallon in GotMead’s gravity chart.
Frequently asked questions
How much honey do I need for 1 gallon of mead?
It depends on the strength you want. For 14% ABV finishing at 1.010 the tool gives 3.24 lb. A weaker 10% mead finishing dry at 1.000 needs about 2.12 lb.
How much honey raises gravity by how much?
This tool uses 36 gravity points per pound of honey per gallon, from GotMead's Mead Calculator, so 1 lb in 1 gallon adds about 0.036 to the specific gravity. Actual honeys differ, so change the field if you measure yours.
Why does the 3 oz per percent rule give a different answer?
GotMead describes 3 oz of honey per gallon per 1% ABV as an approximation. The tool calculates from gravity points instead, which gives 3.24 lb against 2.87 lb for 14% finishing at 1.010.
Does the tool include the honey volume?
Enter your final batch volume. The honey is part of that volume, so top up with water to reach it after the honey is dissolved. Check local rules on making alcohol at home.

Scope
Estimates for planning only. Honey gravity varies by variety and water content, so confirm with a hydrometer. Home production of alcohol is regulated differently in each country, state and province, so check your local rules. Not professional or legal advice.
