So I am brewing what I am calling a wheat pale ale this weekend. One third of the grist will be wheat (the rest malt). I planned to get rice hulls, but completely spaced at the LHBS yesterday (I was too busy drooling over my 2 50 lb bags of grain and all the other specialty grain I was buying). I don't brew with wheat often, so I can't remember the threshold where you need rice hulls. I am assuming that 33% of the grist is enough that It would be stupid to risk brewing without them?
