Try this smooth cocktail before dinner or for brunch.
Guinness stout
Brut champagne
Half fill a Collins glass [1], champagne flute or wine glass with stout and top off slowly with champagne. Stir gently with glass rod.
Tip: For a more elegant look, fill glass first with stout then pour champagne over the back of a spoon to create a dark and light effect. Don't mix.
