Hey brewers I got some flaked barley and am keen to use it. Dave Line's "Big Book of Brewing" highly recommends the adjunct though due to its potential to cause haze the book mainly talks about its use in stouts (where haze obviously isn't an issue).
Has anyone had any experience in using the adjunct and in particular I'm planning a lager this weekend and am wondering what a limit would be for a 22L batch which will probably have about 4.5kg of grain in total.
I'm assuming in using it I can just add it to the mash with everything else. Any advice is much appreciated.
