How We Calculate This
Grain Calculation
Total gravity points needed = (OG - 1) x 1000 x Batch Size. Base malt weight = Total Points / (PPG x 8.345 x Efficiency). PPG (Points per Pound per Gallon) for Maris Otter is ~37, Pale Malt ~36, Pilsner ~37.
Hop Calculation
Uses the Tinseth formula for utilisation: U = Bigness Factor x Boil Time Factor. Hop weight = (Target IBU x Batch Size) / (AA% x Utilisation x 1000). Adjust for different hop varieties and boil additions.
BU:GU Ratio
The Bitterness-to-Gravity ratio indicates beer balance. Below 0.5 is malty, 0.5-0.8 is balanced, above 0.8 is bitter. This helps verify the clone matches the commercial beer\'s character.
