Some scale is needed. Sierra Nevada Pale Ale is 37 IBUs, and that's usually too much for many people. Lagunitas Brewing's Maximus IPA weighs in at 72 IBUs, and they warn on their website that it "may remove enamel from teeth." Dogfish Head 90-Minute IPA is 90 IBUs, and that's enough to give one a shiver. The world record holder is about 3.5 times more bitter than that.
The undrinkability of a beer is no match for the joy of grousing over having a world record, so the Central Florida Home Brewers club is going to attempt to smash that record at a brewing event this Saturday, June 23 at World of Beer Altamonte Springs (155 Cranes Roost Blvd, Suite 1150), starting at 10 a.m (WOB starts serving at 11 a.m.). The only catch is, if you have hops to share, bring them, because they're going to need a lot to build this monster. After the brew session, WOB will be serving up a custom array of hop-crazy beers to quench your brewing thirst. Feel free to either show up on the day or send an RSVP to firstname.lastname@example.org.
