Brewing & Fermentation Calculators
Formulate professional and home-brewed beers, analyze final alcohol percentages from gravity readings, optimize bitterness ratios, profile water chemistry, calculate pitching cell quantities, and manage draft carbonation pressures.
Bitterness Ratio
Calculate the BU:GU bitterness ratio by comparing hop Bitterness (IBU) against malt sweetness (Gravity Units).
Malt Sweetness vs Hops
Brewery Lab Report
Fermentation ScienceBitterness Ratio (BU:GU)
A lower BU:GU ratio indicates a maltier, sweeter finish. A higher ratio indicates dry hop bitterness.
