1/2 oz Armagnac
1/2 oz Cointreau
1 tsp Lemon Juice
1 bottle (Cold) Cola
Funnel the cointreau, armagnac and lemon juice into one small cola bottle (185-200ml), roughly half-filled with cola. Briefly invert the bottle to mix the ingredients. Place in the center of a large glass (tankard, stein or british pint), and fill glass with broken ice. Add a straw to the bottle, and serve.
