You notice your shaker empty, coated in the remnants of a beer once poured. There is no sign of the party slowing down. The sun is high and you’re on cloud nine. You retreat from the group and search out your cooler. Your head bobs with the music while you open the top and reach into the icy depths. You crack open the can. Liquid lace cascades into your glass. An enticing, fluffy, luscious, treat – a Milkshake IPA.
