I'm making an AG Witbier and had planned to use flaked wheat but the LHBS didn't have enough. They did have a barrel of malted wheat which said clearly on it "needs a protein rest". But the LHBS guy said he'd just do a sacch rest and be done with it.
I have a Rubbermaid Mash tun, so it's inconvenient to do a step mash, but I can do it. I could put it all in a pot, do the protein rest, then raise it to 150 and dump the whole thing in the mash tun...
Or I could decoct it.
