Bank's Bitter Clone Attempt - Trouble with BIABacus

by injac

Hi All

I'm using the Graham Wheeler recipe for a clone of Bank's Bitter. For some reason I'm getting an abv of 4.2% rather than 3.8%. Normally I'd let this slide but even if I change the amount of grain I still get 4.2%. Anyone spot where I'm going wrong?

Thanks,

The biabacus default for yeast attenuation is 75%. You can override it in section H. 69% will change it to 3.8%, but it's really up to the yeast in the end/ No software can predict an organic process with any degree of accuracy. This is where experience comes in.

Knowing notty at that mash temp, it's likely going to attenuate 75-80%.
