In case you didn't know, it's #IPA Day, so, at last, Twitter has served some useful function.
Georgeeats is particularly fond of IPAs, and not really just the hoppier the better, although I positively swill in the ale of the big boys. But balance, my friends, balance. You need that malt, the depth, the sweet, to make the bitter sing its terrifically trebly part. Plus hops is half as fun on the nose--forest of pine, groves of citrus. So if you want to make quick work of #IPA Day and opt for a double, you can never beat the best Russian River Brewing's Pliny the Elder. Not that Alpine's Pure Hoppiness or even, if you want to go local, Firestone's Double Jack, are anything to sneeze at (they are something to sniff at, though--breathe deep before you quaff).
As for single IPAs, it's hard to beat Hollister's Hippie Kicker, as fresh as its playful name.
On a side note, does anyone else find it funny that Wikipedia illustrates its IPA page with a photo of Fuller's IPA, when Fuller's flagship ale is its ESB? Oh well. Drink while we can, as the economy is only going to go further and further into the shitter thanks to dirty deeds done debt deal deep.
