The new ingredient is lactose, a.k.a. milk sugar. When Velvet Merlin is brewed with milk sugar to create Nitro Merlin Milk Stout, the effect is similar to adding cream to your dark roasted coffee. The result is a stout that is still dark and roasty, but now with a mellow sweetness and added roundness of body.
