You might find this thread from a year or so back worth a peak. I was asking nearly the same questions you were, so there’s a lot of overlap, but there’s some stuff that’s new too.
Since that thread, I’ve picked up a couple other beers I like, so I’ll throw them out here. I’m not an expert, even remotely, but a recommendation is a recommendation, no?
Sometime last year, my favorite shop recommended to me Arcadia Ales’ Cocoa Loco. It rapidly became my new favorite. When I had to spend a couple of months in New Mexico, I was very disappointed to be unable to get it there. Getting back to Chicago, my favorite shop was in the process of discontinuing it. I found it at a different store, and now end up doing most of my beer & liquor purchasing there, because I can get this beer there. I don’t like the place nearly as much as the old place, and still do all of my wine purchasing there, but I like this beer well enough to go a bit out of my way, to a less “good” place to get it. All of that said, I suspect this review is about right, and that it’s a solid “B” beer. Every now and again, it hits me just wrong, which is a disappointment, and it seems to have a sort of narrow temperature range for tastiness. (Though not as narrow as my previous favorite, linked in the OP of the other thread, the Brooklyn Brewery Double Chocolate Stout.)
Last semester, one of my lab mates introduced me to Bell’s Double Cream Stout, and I really enjoyed it (and it was warm, even!). In the previous thread it’d been recommended, but I was told we couldn’t get it here in Chicago. I guess that changed while I was in New Mexico. I haven’t had it again, so that may have been a fluke, but I doubt it.
Omniscient recommended the Goose Island Bourbon County Stout, and I’ll back up that recommendation, but with a story/caveat (because it makes me giggle). My roommate formerly loved it, and bought a four pack, but after her first couple sips she offered me the bottle. She’s not sure she likes it anymore. I really enjoyed it out of the bottle, but it was too much for me in a wide-mouthed glass (the smell/taste were overwhelming) as they recommend it be served. I gave a bottle to my boyfriend when he came out to visit. His response upon a few sips was, “I don’t think I’m manly enough for that beer.” He is manly enough, but it’s really intense.
Finally, lieu’s recommendation of Chimay is something you should check out too, but don’t be surprised if you’re not a fan. I didn’t like the beige labeled at all, the red was okay, and the blue labeled was decently good. I don’t know what makes a beer “dark” or not, so if you’d asked me, I wouldn’t have called any of them a dark beer, but maybe they are. However, I would bypass all of their beers in favor of their CHEESE. It’s incredibly good. I think I’ve only had the “Grand Classic”, but it was awesome.
Anyway, I hope some of these recommendations help you (one way or another), and I hope you enjoy figuring it all out as much as I have!
