Beer Review by Beer Advocate
This barrel aged porter was tasted off island, and I was told this does not actually exist, but I have been otherwise sworn to secrecy. Poured into a 10 oz wine glass. No head with a little hazelnut colored foam around the edges. no cloudiness. The color of a medium roast coffee (no cream). The nose on this beer is incredible. just a nice slightly boozy coconut aroma, a little dark malts and a cocoa-dark choco tinge to the edges. this should be sold right next to the cans of coco-porter, could easily fetch $6-8/can. It just makes you feel like an afternoon in a hammock. Plenty of rum on the palate without being too hot. The woodiness balances well with the coconut. again the hazelnuts. a slight metallic edge for a moment, but quickly moves to a long pleasant caramel macaroon finish. The mouth feel is a little bit thin, but not off putting at all, I just would like a bit more heft in this in the mouth. Really something one should search out if there are on Maui. As little as I am interested in traveling to hawaii, this certainly is a check mark on the "why the hell not?" side.
