That might have been the case 10-15 years ago (and I guess maybe it still is in some areas that are slow to follow the trends of craft beer) but these days that’s just not the case for most of the small scale craft beer.
Sure, IPAs have become the iconic style of American craft beer and they’ll likely be overrepresented in the US craft market for at the very least the next several decades, but for the past 5-10 years things have moved away from there over saturation that those who dislike the style still like to pretend dominates the scene.
Since the peak of ultra-bitter-IPA-mania, we’ve seen similar (if smaller) fads/trends for sours, NEIPAs, and most recently hazy IPAs (the latter two of which are not in the excessively bitter trend of the IPAs most think of). We’ve also seen fruit beers and seltzers take over, maybe even beyond the degree that IPAs ever did.
In the meantime, we’ve seen these extreme hop bombs relegated to the sidelines of the modern craft beer scene. My personal theory being that lots of brewers wanted to get in on that trend, tried, and found out just how tricky it can be to craft a good imperial IPA, and once people found good ones with wide availability, they stuck with them and the rest of the market dried up. While there’s nuance within hop bills, it’s still all hops. With fruit beers, it’s far easier to do something that nobody else is doing.
