Out your way, I recommend Blake's. A few varieties are offered, and they do sorta make it to MN (they aren't SUPER common, but not rare, either).
I'm sad, though. Junkyard Brewing, located in Moorhead MN (about 4 hours north of me) is releasing their Barrel Aged Peanut Stout (friggin' amazing) this Sat. Due to impending weather and previous commitments, I cannot go.
Appearance is thick and black like motor oil and the aroma hits you with flakey butterfinger candy, fudge, cocoa bean, and slight marshmallow. Flavor starts out big with dark fudge that fades into bourbon and oak tannin then delicious peanut butter cup. Fantastically full-flavored.
Honestly, it's the best of that style in the state. Yes, better than Dangerous Man, which everyone fawns over (yes, DM is top 3, but not the best).
