Starting today, every Thursday will be Cask Ale Night at Jimmy's, the East Village gastropub run by Jimmy "Pots and Pans" Carbone. Cask brew is really something special — an unpasteurized, all-natural ale carbonated only by the action of the live yeast still fermenting inside the keg, and served up via hand-operated pumps from an unrefrigerated container. The taste is more raw and intense in every way: Typically sweet up front, it has a bitter finish, not mention a mouthfeel that's comparable to food. Jimmy's isn't the only bar in New York serving it — nearby d.b.a. has it every night. But if you're a regular there, you now have a new Thursday-night spot.

Jimmy's, 43 E. 7th St., nr. Second Ave.; 212-982-3006.
