Southern Tier, out of Lakewood, NY, are very quietly brewing some of the best beers on the East Coast right now. I expect over the next year or three they'll increasingly become one of the more highly regarded brewers out there. Most of what they do is very good, and much of it is fantastic.
This one is Mokah, a big imperial stout brewed with loads of chocolate and coffee. It's a hefty one, clocking in at 11.2% ABV. Definitely a sipper. (I nursed this bottle over the course of an afternoon.) The chocolate and coffee are strong but not gimmicky, tasting rich and Earthy rather than like cake in a bottle.
Though it's a strong beer, you don't taste that big alcohol content. It drinks very smooth. Delicious dessert beer. Would probably taste nice poured over ice cream or pie, too. I didn't pair it with a cigar, but I expect this would be a perfect match for a dark, musty stick.
Recommended for a nice winter night or after a dinner by candlelight.
