A quick question about alpha & beta values for hops in Beersmith. Beersmith has default values for certain types of hops. For instance, the Ahtanum entry has an alpha of 6% and beta of 5.25%. I recently purchased some Ahtanum from my LHBS. Theirs was 4.5% alpha. So no problem, I can adjust that in Beersmith, but the beta value is still unknown to me. Is there a standard calculation for figuring out the beta value based on the alpha or is that information I can only get from the supplier?
