1. Beer - 1/2 oz. 2. Cola - 8 oz. 3. Blavod Vodka - 1 oz.
Cocktail Mixing Instructions:
Build the vodka and Kahlua over ice and top up with cola.
The beer you must use has to be a stout, like Guinness.
Just splash some in, straight from the tap.
Leave to settle and a creamy head should form on top.
