Rhinegeist rings in Halloween with the second-annual Hopgeist Double IPA festival. If you’re really into IBUs, this is the fest for you. Guaranteed to deliver “hair-raising hop flavors,” the fest features beers from breweries across the country — Dogfish Head, Jackie O’s, 21st Amendment — including super-rares from locals Listermann, Blank Slate, MadTree and more. Rhinegeist will also be debuting the winner of their homebrew collaboration, Homie, a double IPA with mosaic hops. VIP tickets include early access at noon and free food from Dutch’s and Maribelle’s.
Noon-6 p.m. Saturday. $35; $50 VIP. Rhinegeist, 1910 Elm St., Over-the-Rhine, rhinegeist.com/hopgeist.
