Been lurking on these threads for too long, I'm glad to be able to contribute. 2013 Sierra Nevada Narwhal Been meaning to get to this one for a while but I kept getting side tracked. Vigorous pour creates around an inch of thick tan head, combination of larger and fine bubbles. Nose is coffee, bitter chocolate, licorice, bread. Some nail polish remover as it warms up. Taste begins sweet- chocolate, raisin, coffee notes lead to astingent finish with slight alcohol burn. As the beer warms Chocolate notes last longer softening the astringency. Mothfeel is thick and creamy, quite enjoyable. Overall, wish that astringent notes weren't there. I'm also surprised at the bit of heat this far out. Other than that, no complaints for a 5 year old bottle.
