Coffee-based Cocktails: Recommendations
I am gearing up for another cocktail research session with my posse, and was wondering if anyone had some good recipes or interesting ideas of drinks to share. We are hoping to do an exploration with brewed coffee as a base, and adding various liquors to make riffs on Spanish Coffee, Irish Coffee, etc., to see what flavors seem to pair better, and try a few unconventional combinations. We may also experiment making cocktails with coffee liquor as well--White Russians and the like, but we'd like to keep that as sort of a side interest.
What are some of the best coffee-based drinks you've tried? Do you have a favorite coffee roast or blend that you like to pair with alcohol? Interesting flavor ideas as points of experimentation to suggest?
Cheers!

Oh, I've tried the Elysian beet beer mentioned on one of the slides, it was super pretty, and did have a definite beet flavor. Just earthy & slightly sweet, so-so as a beer? I've tried mushroom beers, rose beers, and lots of spicy chile beers. The spicy beers go awesome with burgers, some made from even chipotle can sneak up on you by halfway through the pint (I bet the brewing concentrates the flavor oils quite a bit). I've had Hatch chile ones that are pretty darn mild, and just have more of a vegetal funk.
