Troegs Scratch # 31 Citra of Brotherly Love

From Ed:

Before getting into a description of Scratch 31, we offer a public service announcement from the Troegs brewers:

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?

For Scratch 31, the brothers and the brewers decided to revisit one of our favorite sweet spots – IPA – and have some fun with hop flavors. Dubbed ‘Citra of Brotherly Love’ in honor of Philly Beer week, Scratch #31 has generous amounts of Apollo, Cascade and Citra hops. This is our first use of Citra hops, which is known for an intense grapefruit aroma and flavor.

While showcasing the intense Citra flavor we added additional bitterness with Apollo and Chinook hops as well. Scratch #31 went through a bed of Chinook hops in the hopback and was dry-hopped with Cascade and Citra hops.

Scratch #31 will be showcased at events throughout Philly Beer Week. Also, be on the lookout for Scratch #31 in firkins and pins, which were aged in new wine barrels for about a week before kegging.
