What is the general rule of thumb for how much rice hulls to use? Rice Hulls are cheap but at the same time I'd rather keep them to a minimum when I do use them. I have an Oatmeal stout recipe that uses 1.5# of oats. I tend to use about 0.5# of rice hulls in the mash and I've never had a problem. Cheap insurance.

I've made wheat beers with 50/50 wheat/2 row and I have used 1# of hulls in that scenario.

I've heard one pound of rice hulls per 4 pounds of huskless grain. It really doesn't seem to require much (by weight), since the hulls have such low density.

I probably wouldn't have added it to the oatmeal stout, but I suppose it's better safe than sorry.

You don't need to add very much. I've been using just half a pound for my beer that uses wheat, which is around 5 pounds of wheat.
