Easy
Two-Ingredient
Dessert Drink

A rich and frothy beer cocktail that marries the deep, roasted barley notes of Guinness Stout with the sweet, herbal spice of root beer. This simple two-ingredient drink creates a creamy texture and a flavor profile reminiscent of a grown-up root beer float.

What it tastes like

The aroma is dominated by toasted barley and herbal sassafras. On the palate, the creamy carbonation carries flavors of vanilla, coffee, and dark chocolate. The mouthfeel is medium-bodied with a soft, frothy head, finishing with a lingering sweetness and a dry, roasted aftertaste.
