Quenchers Saloon in Chicago is having an IPA festival on August 3rd and 17th, 2011. What's interesting is that each night they plan on having the IPA's face off against each other according to region. On August 3rd, the West Coast will tangle with the Upper Midwest, and on the 17th, it's the East Coast vs. the Mountains and Plains. Vegas has the West Coast opening at 5-2 odds as the overall favorite.
The lineup will feature stalwarts such as Stone IPA, Port Wipeout IPA, Lagunitas IPA, and also Alpha King, Dark Horse Crooked Tree (mistakenly, I believe, listed as Double Crooked Tree), and Tyranena Bitter Woman. The only real DIPA on the list is Dogfish Head 90 Minute IPA, so they're keeping the lineup on the lighter side to promote broader sampling.
Fans of hops should get some kicks out of this. (That's me.)
