I batch sparge using in a 10 gallon Home Depot cooler. I usually add 8-16 oz when mashing large amounts of wheat, rye, etc. So last week I brewed a dunkelweizen with 51% wheat malt. I forgot the rice hulls but hit 81% efficiency with no stuck sparge or what not. In fact I didn't even realize I had forgot until I though about it a few days later. So I thought I would throw it out to the experts - is there any point using rice hulls when batch sparging? Or did I just dodge a bullet?
