1/2 oz Dry Orange Curacao liqueur
1/2 oz cognac
1/2 oz vodka
1/2 oz lemon juice
1 bottle chilled cola

Funnel the curacao, cognac, vodka 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.
