כיצד לחשב את 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.
נוסחה
ABV ≈ (OG - FG) × 131.25, where OG/FG are original/final gravity
מדריך שלב אחר שלב
- 1Measure original gravity (OG) before fermentation
- 2Measure final gravity (FG) after fermentation
- 3Apply formula to estimate ABV percentage
Worked Examples
קלט
OG = 1.060, FG = 1.010
תוצאה
ABV ≈ 6.5%
(0.050) × 131.25
Common Mistakes to Avoid
- ✕Using Plato instead of specific gravity
- ✕Not controlling fermentation temperature
