Tonight there are two casks at Moon Under Water. The first is another cask conditioned Kvass and the second is an espresso-infused version of the weizen-stout. The Kvass (low alcohol rye bread beer) is certainly worth the visit. Both get tapped at 5pm.
For those who really like to cross bridges, the cask tonight at Spinnakers is their Pumpkin Porter with Ginger and Vanilla. I believe the one gets tapped earlier at 4pm. Plan your hump day accordingly.
