Batch Sparge...Are Rice Hulls Necessary?
 
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?

Eh, I think it really depends from brew system to brew system. What works for one may not for another so they are just a nice safety net. Out of curiosity what kind of mashtun do you use.

In my experience, batch sparging is less likely to get stuck. I believe it is because you stir after every water add and resettle the bed. Fly sparging, the bed just keeps packing down.

It all depends on your lautering system.

I've only used rice hulls for a pumpkin beer with pumpkin in the mash. Haven't had any stuck sparges or clarity issues. Cooler and braid here, too.

I rarely use wheat though...

I'm also a braid guy. I've had problems with pumpkin and wheat. I've noticed that I can go without rice hulls on 25% or less wheat, but I have to run-off fast after stirring the sparge. I vourloff really fast (kind of half a$$) and start draining before the grain bed settles. If I let it settle it will run very slow and possibly even stop. I should mention I use a Corona mill and I get a lot of flour in my crush. So, I guess it's safe to say that it also depends on your crush.

I bought a (100#?) bale of rice hulls from a brewery because I brew a lot with Rye Malt. Regarding stuck sparges, it seemed to be hit or miss without the hulls. It kinda got expensive to buy hulls in 1# or 2# bags, so a asked about it at the brewery. $15 for the bale, I will never run out! Hahahahaha!!

Wow! How big is that bag? Rice hulls are pretty light. Whatever works I guess.

If I'm gonna store something that big, it'd better be fermentable! :D
