How Much Sugar or Honey for Mead?
Reaching a target alcohol level in mead or wine comes down to how much fermentable sugar you start with. As a planning rule, about 17 grams of sugar per litre of must raises the final ABV by roughly 1%. Honey, the sugar source for mead, is only about 74% fermentable, so you need more of it by weight.
From ABV to sugar
Multiply your target ABV by 17 and by your batch volume in litres to estimate the sugar needed, then adjust upward for honey. A 12% mead in 4 litres needs well over a kilogram of honey. This is an estimate — yeast strain, temperature, and completeness of fermentation all shift the real result.
Trust the hydrometer
No formula beats measuring. Take a starting gravity reading of your must; it tells you the potential alcohol directly. Adjust with more honey or water until the gravity matches your target, then let the yeast do its work and confirm with a final reading. The calculator gets you close; the hydrometer gets you there.
Frequently asked questions
- How much honey for mead?
- Roughly 17 g of fermentable sugar per litre per 1% ABV, adjusted up because honey is only about 74% fermentable.
- What starting gravity for 12% ABV?
- Around 1.090, though yeast and fermentation completeness affect the outcome.
- Do I still need a hydrometer?
- Yes — it's the only way to confirm your actual gravity and finished alcohol.
