Shamrock Stout is a tradition for us here at Goose Island for St. Patrick's day because it just tastes so good and our Irish roots run deep. Fun fact, Goose Island was home to Irish Immigrants in the late 1880's! We load up our Bourbon Barrel-Aged Stout (wink, wink) with Chocolate, Mint, Vanilla, and a touch of lactose as a tribute to one of mankind's greatest inventions, the Shamrock Shake. Always limited, and always a tasty treat. Sláinte!
