Notes

This is a classic London Porter recipe. It uses the rumoured Fullers London Porter grain bill of 12% Brown Malt, 10% Crystal and 2% Chocolate Malt. I've used Dark Crystal to give some more depth to it. The beer will have a dark brown colour with a hint of amber. Yeast used was London 1028 which is good for brewing Porters but London III 1318 can also be used for a less dry finish.
