Someone awhile ago mentioned Magic Hat for being douchecanoes to a local brewery. Funny that: they did the same thing to a Seattle brewery that locally distributes, keg-only. Said brewery (Georgetown) had the temerity to marget a "9lb. Hammer" porter. Which led Magic Hat to send a cease and desist, which both obviously made sense since a porter and fruit beer are identical and wasn't worth the lawyer fight. Hated 'em before, hated them doubly ever since.
Not new, but I feel like a lot of this thread is people unhappy with beers from the other side of the country/world not meeting the "hype" or being what they hoped for/expected. And, as someone said with regards to Pliny: that's the fault of beer drinkers, not (usually) the brewery. Don't drink Green Flash West Coast from the bottle anywhere, let alone the East Coast/Europe. Similarly, don't waste your money on Saison Dupont in bottles in America (go to Belgium and drink the dry-hopped version and cry you don't get it daily).
So, in the spirit of only hating on beers from where I've lived:
Rogue. Nice marketing department, guys. Call me back when you've moved beyond the late 90s/done something interesting/dropped your prices by 30%. Just pick one.
21st Amendment. DIAF.
Someone mentioned Mac and Jack's African Amber. So many good beers in Seattle are not available elsewhere. This is most assuredly not one of them.
Pretty much anything Boulevard does. It's fine, but holy Christ people in Kansas City think Boulevard ****s magic fairy dust.
Every. Single. Brewery. In South Carolina. North Carolina has fabulous beer, but there's now a local craze down here where decent NC taps are being displaced by SC crap. We're talking local-CA-brewpub-circa-1995 quality beer (I move a lot). Westbrook does a phenomenal gose, everything else they brew sucks. Holy City has a great porter, not much else is worth drinking. Brewery 85 and anything out of Columbia are total absolute swill.
Aaaand since we're talking about SC, let's give a shout out to an overly-priced, overly-hyped, and eminently mediocre gypsy brewer: Evil Twin!
tl;dr: I secretly despise nothing!
