I brewed this back in January, as had a very vigorous fermentation even though I kept the temperature in the low 60's. I just kegged it last night. When I tasted my gravity sample, it tasted somewhat "hot" and harsh to me. My calculated ABV is 6.4%, so I'm not sure if what I was tasting was due to the higher-than-normal alcohol content, or if I might have some fusel alcohols present. The fermentation was vigorous enough to suggest it may have produced some off-flavours, but I fermented at the same temperature as all my other ales (basement, in a plastic pail full of water, covered with a wet t-shirt).
Has anyone else detected somewhat "harsh" flavours in this recipe initially? Will this age out? Will the CO2 help it mellow? Is this normal for this recipe?
