I'm going to give this a go on my next batch after xmas, hopefully it will turn out ok as if it's anything like the real stuff, it will be lovely!

3450g Marris Otter Pale Malt
560g Crystal Malt
50g Chocolate Malt
Copper Hops (90min Boil):
20g Challenger Hops
10g Progress Hops
Late Hops:
15g Fuggles
10g Goldings
Target O.G - 1.041
I'll be using their yeast so it should turn out very similar!
