A collaboration between BrewDog up in Scotland and Victory Brewing over in Pennsylvania, USA. U-Boat is a Smoked Porter which was brewed to imperial strength using a lager yeast, which was then matured for almost 2 months before setting sail to a glass near you. A gorgeous, smoky, sweet brew.
Ask #WhiskySanta for BrewDog U-Boat.
