I'm thinking of using about 13% raw and 39% malted wheat in my next Wit. The rest pilsner and a little vienna.
i ended up going 40% pils , 40% raw wheat , 20% wheat malt
i put the raw wheat through the mill twice and then again with the pils
didnt need any rice hulls and it stil resulted in a really quick effortless sparge.
i think i will need to crush the raw wheat a bit more for my next attempt, just to try and get the effeciency up a little more.
