Blackberry Milkshake Porter is a 9% ABV Porter brewed with lactose from Griffin Claw Brewing Company in Birmingham, Michigan. Griffin Claw teased a Rocky Road Stout, Chocolate and Vanilla Porter, a Mole Stout, along with this Blackberry Milkshake Porter on their Instagram, and since I was in the neighborhood last week I figured it was high time I stopped by to see what all the fuss was about. I’m always interested in different “Milkshake Styles”, but how does a milkshake porter differ from a regular porter? Watch to see if Griffin Claw set themselves apart with this one!
