Very interesting. More fruity than sour (although it's definitely tart). The cucumber and lime and mint are all very clear here and leave a highly unusual, fresh, impression.
After the other dark beers here, this one is surprisingly sweet. Not syrupy, but there are fairly clear banana notes, a bit of fudge, maybe marshmallow.
An excellent coffee stout. Not sweet like many milk stouts, just creamy. The coffee flavor is complex, chocolatey, and you can just feel the bean here.
