I bottled it and bought a case of Carlsberg in the end and 24 bottles of Magners bought in the North.
They drank on me;
20 Litres of Dry stout served on Nitro
15 Litres of Boston lager clone
10 Litres of Stella Clone
10 Litres of Kolsch
20 Litres of my own carbonated cider, backsweetened slightly.
They left behind a case of Carlsberg and 24 bottles of Magners!
I'm well chuffed.
