Default Grain bed optimization & rice hulls

Hi,

Is it OK to add rice hulls to a non-wheat/high gravity mash to increase the minimal depth of a grain bed containing only malted barley grains?.

If it is Ok what is the recommended maximum ratio of hulls to grain.

Thanks

I use rice hulls in almost every batch. I never calculate the ratio. 2 or 3 handfuls will do the trick.

I have yet to use them, as long as the sparge drains slowly I never had a stuck sparge. As for increasing the bed depth, Make bigger batches or use a smaller diameter tun.

You typically use rice hulls with grains like wheat, rye, etc., grains that typically have a problem with lautering and yielding stuck mashes. I've used them once and didn't have any problems. Now, when I use those types of grains, I do a protein rest around 122 for 20 minutes and never have any issues. I honestly don't see a reason for rice hulls. If you want to use them, go for about 8 ounces to 1# tops per batch.

You know I just used rice hulls for the first time on Friday and I got to say I drained off my mash as quick as it could flow, sure most of the batches I have done didn't need them, but I think if your having problems with stuck sparges throw in a couple of hand fulls it can't hurt and it will save you some headaches if you are having stuck sparges. I used them on the last batch because I had 50% wheat in the grain bill but I have enough rice hulls stocked up I'll probably start putting them in my barley malt batches as well for extra filtering material as I tend to crush on the fine side.

Some people (like Biermuncher) use a 1/2# in many of their batches, just to make sure they don't get a stuck sparge. I don't know of any adverse effects in that quantity.

I've researched this a bit.

Is Maris Otter more prone to stuck sparges than good ole american 2-row? I had a recipe yesterday that was MO, Aromatic and some crystal and I got my first stuck sparge ever... I ended up dumping everything out into a bucket to see if something happened to my braid (not) then dumping everything back in and adding nearly all of my sparge water into the cooler with it...I let it sit for 20 minutes and drained, adding more sparge water till I hit my volume...

Surprisingly despite the problem, I hit my numbers perfectly...

Are we supposed to use a different water/grain ration than the usual 1.25/pound? I just followed what beersmith told me....

I was thinking about ricehulls while this was happenning yesterday.

I never had any changes in lautering when I switched to Maris Otter. I didn't change my mill settings and I used the same water:grain ratios that I had originally established in the recipes. Maybe you just had one of those days?

Yeah....I figured it was either that or something to do with how I have my circular braid attached, it might be wearing out....But yeah, it was one of those kinda brewing sessions I was pleasantly surprised though when my preboil gravity and my SG matched what Beersmith said they should....

Of course I'll probably never ever have that level of efficiency again....
