Troegs double bock, traditionally named Trogenator. The horns are to invoke billy goats, a pun on the German word for bock. At 8.2%, the alcohol levels are low for a double, but the flavor is fully as rich and chewy as to deserve the label "liquid bread" given to it by the monks who started brewing it. Trogenator is sweet but not cloying with flavors of malt and grapes.
I will be happily surprised if Craft Beer Cellar can beat this in future days.
