Beer held at a constant temperature and pressure will absorb a set amount of carbonation. As temperature goes down, it will absorb more, up and it can’t hold as much. So, what happens if a slightly carbonated beer is put in to a sealed barrel and the temperature hits 90+ F?

So, there went some of the portion of Scratch #31 (aka “Citra of Brotherly Love IPA”) destined for Philly Beer Week Firkins. We still have plenty to work with, but it always sucks to see beer hit the ground. #31 is a classic IPA recipe with generous amounts of Apollo, Cascade, and Citra hops. New to us on this go are the Citra hops which are known for their intense grapefruit aroma and flavor. I think you’ll agree that they definitely do the job on giving that classic American IPA citrus aroma. Look for it on tap or on the bar at Philly Beer Week, June 4-12.
