Hi! Firstly if you like pale American style IPA give this one a try it's lovely! (Got mine in Asda 660ml) I'm planning my next brew and would like to make something similar to BrewDog Instamatic which is: "Pale malt, wheat and flaked oats. Hopped with Citra, Ahtanum and Simcoe." My question - should I subtract the weight of oats and wheat from an otherwise pure barley grain bill? In my last beer I used 5kg pale maris otter. If I used 500g oats and 500g wheat, (firstly is that a sensible quantity?) and secondly do I then only need 4kg barley to reach my original gravity target?? Or does oats and wheat have less or more extractable sugar in them?
