I usually assume when Europeans complain about American beers, they just are complaining about our “domestic” beers like Bud Light, Coors, PBR, etc. which makes sense, they are our bottom shelf beers.
I recently chatted with someone at a party who said “no, all American beers are bad” including microbrewery beers.
I’ve never been to Europe so I wouldn’t know, but I do like my Left Handed Milk Stout, NWPAs, and hell even the hipstered out IPAs.
Are these what y’all are referencing?
That’s kinda the difference - local specialties mostly can’t be beaten on their own turf. Also, in America you’ve got to actually seek out the good stuff and go local, the InBev stuff is meticulously targeted at swine with no taste.
