Beaten to the beat down by the Wombat, but I’ve won numerous ribbons, as well as a few Best of Show trophies for a style that you say doesn’t exist.
Excellent choice. And by excellent, I mean dreadful.
I wouldn’t write off all chili beers on the basis of that, though. Jaipur Brewing Company in Omaha makes an excellent jalapeño ale. The flavor is well-balanced and the heat creeps up subtly. I’ve also brewed one myself. It was to my liking, though I’m not sure others would agree.
I don’t especially like hoppy beers either, but for me, Arrogant Bastard is so far over the top that it goes all the way around and starts to taste like something else. I can’t drink it all the time, but it’s a good jolt to the palate once in a while. Plus, even if you hate the beer you have to love their website.
Personally I think Sam Adams Cranberry Lambic tastes more like a Berliner Weisse than anything else. It has that same sort of tartness to it. I just wish they’d start selling it here again.
Oh, and my vote for the OP: canned Schlitz. It has this horrible metallic tang. It’s one of only two beers (along with Mickey’s malt liquor) which have made me do a spit take.
Can cider be included in this thread? 'Cos the worst thing I’ve ever drunk came from a little apple farm in Somerset, England where the guvner had a barnhouse brewery happening.
Now I can drink just about anything, and a lot of it too. But this stuff was truly rank: I’d had such high hopes of getting a genyoowine dinkum cider that I was literally crushed with the disappointment. Had to head to the nearest pub to wash the nasty out of my mouth. 
Oh btw, the worst Cornish Pastie I’ve ever had the displeasure of eating came from Cornwall. 
Cider is another thread-and since I’ve had the “pleasure” of a glass of hot spiced prune cider, I doubt any of you would be able to top it.
If the topic is prune-based horrors, open that thread and I will teach you Lovecraftian terror that is the traditional Ukrainian Xmas Eve meal.
You start that thread, and it might end up in The BBQ Pit.
Oh you really don’t want to barbecue prunes. The smell is intolerable, and you can never clean them off the grill afterward.
Sammiklaus beer - 14% and pours like cough syrup.
