Hop Alpha Acid Loss Calculator


Brewer's Lair has added a new calculator for you to predict decreases in the alpha acid content of your hops based on their age and storage condition. First, you input their original alpha acid content in percent. Then, you input their percent loss rating at 6 months, the storage temperature, the storage conditions, and the storage age of your hops in days. The calculator then predicts the adjusted alpha acid content of your hops. If the hops you plan to use are not fresh, computing this adjusted alpha acid value is useful when deciding how much you need to add to hit your target bitterness.

Check out this new tool in the Lair Brewhouse.
