Many of our beers are inspired by our fellow brewers and none more so than the guys at the Kernel. Their Imperial Brown Stout is a luxurious, warming, cascade of chocolate, coffee and fruit flavours and we wanted to make a beer in its image.
This is a real traditional London beer style. Brewed up in vast quantities in the 19thcentury during London brewing golden age, our recipe is based on a beer made by the Barclay Perkins Brewery in 1832. The recipes can be found in the wonderful “Old British Beers and How to Make Them” by John D Harrison of the Durden Park Beer Circle. If you want to know more about the rich brewing history of London, we’d recommend checking out beer writers Des DeMoor and Ron Pattinson.
Cast Iron Billy, at 10.5% is a big beer, but by adding some brewing sugar, using a neutral yeast strain and ageing the beer, it becomes smooth and characterful. We blend Maris Otter, Brown, Amber, Chocolate, Black malt and Roast Barley in the grist and add a bit of sugar to the kettle. We package in keg and bottle and store the beer in the brewery for minimum of three months to allow the flavours to mellow and blend together. It’s a beer that really compliments a sweet or rich dessert as it warms up and is best enjoyed by the fire side on a cold winter evening.
