100% agreed. I think a few things go into it:
- Americans don’t really get exposed to good lagers and pilseners. We get Bud[1], not Budvar. So there’s no expectation that beers in those categories could possibly be “good”. IPAs don’t have the same baggage.
- For the same reason, it’s easier to differentiate from the big brands on a supermarket shelf. You get to be your own category, not just the more expensive version of what people think of as regular beer.
- Maximalist American food culture. It’s like when bacon became a meme and suddenly everything was covered in bacon. Fatty ramen became a trend for the same reason: it’s a simple, super-saturated flavor that’s easy to crank up to 11.
- Like you mention, it’s easier to brew.
The worst is when you’re given a menu of 40 indistinguishable IPAs all called like “HOPULATOR 9000” or whatever. Sometimes I just want to go out for a brewski, why did that have to get complicated?
[1]You know what? Bud on draft is fine. It’s not the best, but I like it, and I’ll certainly take a $3 pint of bud over a $9 snifter of “gnarly Steve’s surfs up mango hop smasher” or whatever.
