I also just realized I had an English PA/ESB in keg since sep 15 (had only consumed about 1/3 of it). it was OG 1.055 FG 1.008, 6.2%abv . 95% MO, 3.1% crystal 80, 1.9% extra dark crystal. 40IBU of challenger. WLP002.
Just poured a pint and man has this matured nicely. Might have to think about throwing this one in the swap also.
edit: think I will I hit it with 3oz of challenger week before we ship to give it back that fresh hop aroma to compliment the taste.
