A special release for Old Nation's 10 year anniversary, and named after an iconic rant on the hypnotic stupidity of chickens, Flat Brain is anything but dim. A rich malt body delivers caramel and toffee, while bright Citra hops burst with mango, grapefruit, and lychee. Smooth and complex with a crisp finish, it’s a bold, tropical-leaning brew that rewards focus—and maybe even invites a little hypnosis.
