General Notes:

Used yeast cake from batch #70.
Tasting Notes:

Tasting notes taken 4 October 2013, 35 days after kegging. Dispensed from kegerator into a tulip.

Appearance: murky brown hue with a moderate haze and two thick fingers of creamy caramel-tan foam. The head is dissipating slowly and leaving a nice chunky lace on the glass. Color is a bit darker than I intended; I wanted to darken it just a little but I guess 4oz of chocolate was just a bit too much. (4)

Smell: fruity, oxidized malt. There's also a definite hop aroma, but it is kind of hard to pin down. I think the hops are kind of fruity in nature and blend in with the fruitified malt. Not bad, but not particularly intense nor to-style. (3.5)

Taste: starts off with a strongly alcoholic, astringent flavor; the sweeter malt flavors and light fruitiness then come in. Midway through, the bitterness takes over -- and boy, is it bitter. Bam! It never really gels well, but overall the flavor is not bad. (3.5)

Mouthfeel: medium body due to the beer's frightningly high attenuation. Creaminess is nice but not perfect -- mash higher next time. (3.5)

Drinkability: very drinkable for a 10.1% ABV beer, although more of a sipper than a quaffer. I haven't really found a great food with which to pair it -- it's just way too bitter to really go with much of anything. That said ... I can easily drink too much of this in one sitting. (4)

Overall score 3.65 (B). This beer came out something in between an Imperial IPA, a barleywine, a strong ale and an old ale. The oxidation really adds to the barleywine/old-ale perception -- maybe don't leave it in the plastic primary for 146 days, eh, guy? It's an interesting beer though. I may go for a more intentional old ale again in the future with the idea of a 5-month primary; something a bit less hoppy maybe.
