如何计算Fermentation ABV
learn.whatIsHeading
Alcohol by volume (ABV) is calculated from starting and finishing gravity readings. The gravity drop indicates how much sugar was converted to alcohol by fermentation.
公式
ABV ≈ (OG - FG) × 131.25, where OG/FG are original/final gravity
分步指南
- 1Measure original gravity (OG) before fermentation
- 2Measure final gravity (FG) after fermentation
- 3Apply formula to estimate ABV percentage
例题解析
输入
OG = 1.060, FG = 1.010
结果
ABV ≈ 6.5%
(0.050) × 131.25
常见错误注意事项
- ✕Using Plato instead of specific gravity
- ✕Not controlling fermentation temperature
