Notes

Smooth coffee-chocolate "stout". Made with Crisp experimental malt Smooth Chocolate Malt (7.5%). The other roasted malt used is the de-husked Weyermann Carafa special type III (4%) for a smooth darker malt to colour. The bittering hops used are Challenger added with first running. Fuggle is added for an earthiness.
Lactose (3%) is added to boost body. Cold steep coffee (150g steeped overnight in 1L water at 4C) is added in the last 10 min. of the boil for aroma and a slight bittersweet coffee note to the beer. Fermentation is done as cool as possible (16C) to reduce fruity esters with London Ale 1028.
This is a heavy breakfast stout which should be drunk slowly and savoured.Should be served on nitro to get a smooth creamy head
