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.
الصيغة
ABV ≈ (OG - FG) × 131.25, where OG/FG are original/final gravity
دليل خطوة بخطوة
- 1Measure original gravity (OG) before fermentation
- 2Measure final gravity (FG) after fermentation
- 3Apply formula to estimate ABV percentage
أمثلة محلولة
الإدخال
OG = 1.060, FG = 1.010
النتيجة
ABV ≈ 6.5%
(0.050) × 131.25
أخطاء شائعة يجب تجنبها
- ✕Using Plato instead of specific gravity
- ✕Not controlling fermentation temperature
