At Galveston Bay Brewing with my son-in-law. Trying a unique nitro rum barrel aged Stout. Wow! Huge blast of rum. Not sure if there's any beer in this glass or not. Seems much stronger than 10% alcohol. Thin soft texture. Roasted coffee blends with the rum. Flavor hits hard, puts a shiver into you. Finish gradually recedes into a slow warming burn. This is like a glass of rum with a splash of beer added. Intensely strong. Don't really think I could handle another. A one and done for me. PS: Insane son-in-law loves it.
