Mead Calculator
Original gravity, alcohol, and style band from honey weight, batch volume, and moisture.
What it does
Mead is honey, water, and yeast, and everything follows from the gravity the honey creates. This calculator turns honey weight, batch size, and honey moisture into original gravity, alcohol, and the style band.
Honey contributes about 36 to 40 points per pound per gallon depending on moisture. Drier honey is denser in sugar, so the same weight ferments stronger.
The numbers trace the American Homebrewers Association table: 13 % moisture carries 40.29 points, and each step wetter drops at least a point. Pick the row that matches your honey.
Alcohol reads as the fully dry ceiling, since meads often stop sweeter when yeast tolerance runs out. The style band follows the classic hydromel, standard, and sack ranges.
How to use
- Pick imperial (lb and gallons) or metric (kg and liters).
- Enter how much honey goes into the batch.
- Enter the batch volume in the fermenter.
- Pick the honey moisture closest to your jar.
- Read the original gravity.
- Read the ABV ceiling and the style band.
Formula
- PPG
- Points per pound per gallon by moisture: 13 % 40.29, 15 % 39.35, 17 % 38.44, 19 % 37.51, 21 % 36.58.
- lb
- Honey weight in pounds (kg converted inside).
- gallons
- Batch volume in gallons (liters converted inside).
- OG
- Original gravity, 1 plus points over 1000.
PPG values follow the AHA points per pound per gallon table for honey at each moisture. The ABV line assumes fermentation finishes at 1.000; stop sweeter and the real number lands lower. Bottling above the yeast's tolerance needs stabilization or the batch can restart.
Worked example
Example: 15 lb of honey in a 5 gallon batch
Honey 15 lb, volume 5 gallons, moisture 17 %.
- PPG at 17 % moisture: 38.44.
- Points: 15 x 38.44 / 5 = 115.3.
- OG: 1 + 115.3 / 1000 = 1.115.
- ABV ceiling: 0.115 x 131.25 = 15.1 %.
- Band: standard, 1.080 to 1.120.
- Metric mirror: 6.8 kg in 19 L gives the same 1.115 and 15.1 %. Tool shows 1.115, 15.1 %, standard.
Reference table
| Moisture | Points per lb per gal | Original gravity | ABV ceiling |
|---|---|---|---|
| 13 % | 40.29 | 1.121 | 15.9 % |
| 15 % | 39.35 | 1.118 | 15.5 % |
| 17 % | 38.44 | 1.115 | 15.1 % |
| 19 % | 37.51 | 1.113 | 14.8 % |
| 21 % | 36.58 | 1.110 | 14.4 % |
Limits
- PPG assumes typical honey; variety and actual moisture shift the points.
- ABV assumes dry fermentation to 1.000; sweet batches finish lower.
- No nutrient, pH, or yeast selection guidance.
- Volume is batch volume, not the water added.
Common mistakes
- Measuring honey by volume; jars and squeeze bottles hide the real weight.
- Ignoring moisture, which moves gravity by more than ten points across the range.
- Reading the ABV as guaranteed when yeast often quits before fully dry.
- Planning a sweet mead and still expecting the dry ABV figure.
- Scaling honey roughly; a tenth of a pound is about a gravity point in a 5 gallon batch.
Try it yourself
Quick checks. Answers sit tucked under each question.
12 lb of honey in 5 gallons at 13 % moisture?
1.097 and 12.7 %, standard band.
3 lb in a 1 gallon batch at 17 %?
1.115 and 15.1 %, the same gravity as 15 lb in 5 gallons.
10 lb in 5 gallons at 21 %?
1.073, hydromel band, about 9.6 %.
Questions
How much honey for a 5 gallon batch?
About 12 to 15 lb lands in the standard band near 1.115. Sweeter sack style goes higher, and session strength goes lower.
Does honey moisture matter?
Yes. The same 15 lb swings from 1.110 to 1.121 across the moisture range, which is more than a percent of alcohol.
Will it really hit the ABV shown?
The figure is the dry ceiling. Yeast tolerance, nutrients, and temperature decide where fermentation actually stops.
What are hydromel, standard, and sack?
Classic strength bands: hydromel 1.035 to 1.080, standard 1.080 to 1.120, and sack 1.120 to 1.170.
Does the honey variety change the number?
The sugar points stay close; flavor, color, and aroma change a lot. Use the moisture row that fits your jar.
Does metric mode agree with imperial?
Yes. 6.8 kg in 19 L is the same ratio as 15 lb in 5 gallons, and both read 1.115.
