I'm trying to make a coffee brown ale similar to the one at a local brewery (Perrin Brewing Co in Grand Rapids, MI) and after an email exchange with the head brewer (who answered my email almost immediately, one more reason the craft/homebrew community kicks ass) on the coffee addition to this beer I need to figure out how to convert 25 lbs coarse ground coffee in a 30 bbl batch to oz per gallon on my system. A check with google and the conversion i get is roughly .5 oz per gallon to 1 pd per bbl. So that makes 2.5 oz per gallon at one pd per bbl, but it's not 1 to 1, so I come up with a .83 pds per bbl rate for their batch, which looks like .33 oz per gallon on mine. Sound right?
