For a few brews now if have tried a style called Brupaks(Brewers Choice Traditional IPA is a dried ingredients beer kit using Tea bag technology. No boiler is required. A wll hopped Pale Ale in the style shipped to India in the 19th Century. a 5 Gallon kit that can be made as a light session beer, medium bodied or full bodied Premium beer.).As this system uses grains and hops in bags and mixed with 6 litres of boiling water, then with a large bag of malt extract(top up to 40pints with cold).
Could i not just replace the hops and grains they supply you with and use different styles in muslin bags?
