Made this beer last month and it turned out really well! I didnt let it sit in the primary fermentor for 3 weeks, I moved it after 2 weeks, fermentation finished basically in 2 days and it was explosive. blocked my air locks multiple times and I had to baby sit them for a day until the aggressive fermentation settled to something my airlocks could manage. Yes recommend running a blowoff tube.
I enjoy the flavor, it is a heavy strong beer. My OG was 1.080 and the FG was about 1.030. ~ 7.5% abv. I made a 10 gal batch and I have to break up the mash into two separate mashes, I only had 10 gal mashtun and the amount of grains this thing took was more than the mashtun could handle *o*.
Pics of the life of this beer posted. Enjoy.
