I know this is my first post, been lurking for a while. I actually just tried the quad tonight. I got it a good week or so ago and meant to share it with my wife, but she never got more than a taste. Personally i really liked it, slightly sweet and malty, also lightly to moderately hopped. Over all very smooth and i would definately not hesitate to buy it again. It reminded me alot of a homebrew quad i tried at the tn cigar and brew fest. I actually found this particular thread while searching hoping to find a recipe to make it myself.
I tried the la trappe quad hoping for similar but that wasn't dark enough and was quite a bit more bitter than i expected with my limited quad experience. All in all i definately liked it and if i can't find a recipe i'll pretty definately be picking up a bottle or 2 at a semilocal store ($10 for the 1pint 9.4oz bottle) anytime i have an excuse to head over to that part of jackson. All in all i liked it, and the sam adams imperial stout i followed it with, lol.
