Wyeast 1084 - Irish Ale
General Notes:

This was supposed to be a stout, but ended up more porter-looking.
Tasting Notes:

Tasting notes taken 1/27/2010. Poured from bomber into a tulip.

Appearance: quite black/dark brown with a ruby tinge when held up to the light. Head is a light tan and two fingers in depth, generously helped by the tulip glass, and dissipated rather quickly. Perhaps I could have called this a stout after all. (4)

Smell: very rich coffee aroma. There is a little sweetness and chocolate with some alcoholey fruit flavor around the edge, but these characteristics are quite subtle and offer a nice complement to the coffee malt aroma. (4)

Taste: very smooth coffee flavor. Hops come through a little and are floral in nature; they complement the malt profile pretty well. There's a bit of an over-bitterness which might be either the hops or the roast malts; I bet tuning these down in the future would help this a little bit. Overall, it's alright; could be better, but by no means bad. (3.5)

Mouthfeel: body is on the light side of medium and has a little bit of an astringent quality, but this bottle carbonated up quite nicely. The well-integrated carb yields a creamy yet silky texture which I quite like. (4)

Drinkability: quite drinkable despite the 7.1% wallop it packs. I could probably back off the IBUs a little bit and with my improved mashing techniques end up with a pretty respectable Baltic porter. Sadly, the astringency and bitterness are somewhat cumulative, so it's not quite a session brew. (3)

Overall score of 3.7 (B). Not bad, really, but it could definitely use some fine-tuning to improve it.

7/27/2010: additional notes taken a nice round 6 months since the official tasting. Tonight, I'm drinking the last bottle of Procrastination. While most of the above comments are still relevant, I want to note that the astringency is dialed way back from January. A bottle-conditioned brew really is a living thing.
