Notes:

It's a good beer, but not what I was expecting. Tastes more like a rich porter. Too light TASTING in body, yet the mouthfeel is a little bit viscus like it should be. A bit too much of a burnt taste (too roasty) but not necessarily overpowering. It's definitely not 10.5% ABV... I don't taste alcohol at all like I would expect. Under-carbonated. I'm wondering if cooler fermenting temperatures hindered fermentation. Ultimately probably should have fermented about twice as long and only dropped fermentation temperature the last 5 or so days. Going to let the remaining 6 sit for at least another couple months before trying another. Will wait for a guest to pop the next one open, most likely. But I'm sure it will taste better when that time comes.
