I'd like to ask the guys who use rice hulls in their mashes: how much do you put in? I'm getting set to do a weisse using a grist that's about 60% wheat, and the last time I made this beer the sparge got pretty sticky. I'm planning to toss in some rice hulls this time, but I don't know how much is enough. With about 11 pounds of grain in the tun, would a pound of rice hulls be enough? Two pounds?
