I would argue that the IPA fandom hasn't diminished (especially out west), but other things have arisen alongside it.

On the east coast, I see an impressive number of sours and dubbels coming out of craft shops, and the midwest is big on bold, malty offerings like ambers and oatmeal stouts.

I haven't seen IPAs drop in popularity (I much prefer darker, maltier beers), but I do feel like more recently IPAs have tried to use hops in more interesting ways instead of just going for XIPA/DIPA. I hope if hops stay around this trend continues.

I would have thought the hops shortage of 2008 would have forced breweries to try something else, so by now it's probably demand driven. I hear there's a new hops shortage coming up.

Yeah, I don't know that I've seen an actual drop, but there definitely seems to be more development in other areas. Craft beer aisles keep growing, and a good chunk of what gets added isn't IPAs. Still not enough porters and dark ales for my taste, but I'll take what I can get.

I'm definitely glad to see the push into more interesting IPAs. I'm seeing more whites, doubles, and other exotic stuff. Plus people finally seem to be learning that 80 IBUs demands some malt and complexity to make something drinkable.

(For some reason, the Wyoming/Idaho region is awesome for dark beers. Something practical, or just a regional fascination? Try some Wake Up Call or 3 Picket Porter if you can find 'em.)
