This is another tricky one to find, but if you can snag this 10% Imperial Stout from the California brewery, you should.
Dads getting into beer are more likely to get really into stouts than they are IPAs, and Imperial stouts do not mess around. Plus, if you start humming “Mama’s Little Helper” while you pour it, it’ll subconsciously remind your dad of the Rolling Stones, which he’ll love.
