For this second edition our Frucht und Eisen Sour Series, we loaded this Kettle Sour with Wild Berries, or what the Germans call Waldfrucht, a mix of blackberry, raspberry, and blueberry. The beautiful purplish red color even leaves the foam looking pink. Refreshing and light, this beer drinks like a tart berry lemonade. Perfect to crush in warm weather or to bring your own warmth to a cold day.
