Founders Bottle Shop Series Highball Drifter is an Imperial Brown Ale by style. There’s a new sheriff in town – meet Highball Drifter, a barrel-aged sipper inspired by our favorite bourbon-based cocktails. The second entry in our Bottle Shop Series, Highball Drifter presents aromatics of caramel and vanilla, dried fruit and spice while hints of cherry and bitter orange peel whisk you away like a tumbling tumbleweed. Call us old-fashioned, but we think you’re going to love it. This imperial porter is 11% ABV and 25 IBUs. In this beer review, we will take a look at the color, smell, and taste.
