A classic and simple two-ingredient cocktail combining equal parts chilled stout beer and champagne. It offers a unique contrast between the rich, malty notes of the stout and the crisp, bubbly effervescence of the champagne, creating a surprising and elegant drink.
Ensure both the stout and champagne are well-chilled before mixing for optimal temperature and effervescence. To achieve the traditional layered effect, pour the stout first, then gently layer the champagne over the back of a spoon held just above the stout's surface. For a simpler approach, simply pour the champagne slowly into the stout. A dry stout and brut or extra brut champagne are classic choices, balancing the flavors.
