Chaptalisation calculator
Sugar needed to raise a must to a target Brix, accounting for the volume the sugar adds. Regulated or banned in many regions; this is a calculation, not a recommendation.
Sugar to add
844 g
Potential alcohol after
12.7 to 13.8%
Chaptalisation is regulated or prohibited in many wine regions. Check what applies where you are before doing this to anything you intend to sell.
Relation used
Mass balance, corrected for the volume the sugar itself adds. If another calculator gives you a different answer, this is usually why. Neither is wrong; they are different published relations describing the same chemistry, and the useful thing is knowing which one produced the number in front of you.
