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?
I’m particularly fond of Belgian beers and my partner is fond of German beers. They’re of course not as good in America as the real thing, but there are definitely some solid options. In fact that’s what I will say is nice about American beers: you can find something decent of any style of beer you can imagine, and some truly excellent ones in a handful of styles as you mentioned already.
