Default Rice Hulls Questions

I'm working up a recipe for a simple Hefe and I have some questions regarding rice hulls. I think I've answered some of these from other posts, but I'm not 100% confident I've got this right. I'll be adding 0.5 lbs of hulls to 10.5lbs of grains.

Water Absorption? Rice Hulls will not absorb water.

Strike Water Temp? Rice Hulls will effect this. My calculations should be for 11lbs of "grain".

Water to grain ratio? Should I count the rice hulls or not?

Thanks.

Rice hulls do absorb water. Really, just account for them as if they were any other grain.

Actually I like to rinse soak and rinse my rice hulls first before using them. They are not exactly clean in some cases and by pre-soaking them, you don't have to worry about them soaking up any precious wort.

+1 the few times I used them they looked pretty dirty so I didn't want to just dump them in. As TexLaw said, after that I just treat them like any other grain in regards to water amounts.

Do you actually weigh out 1/2 lb of rice hulls? They aren't very heavy and 1/2lb is A LOT of rice hulls. A few handfuls usually do it for me, and I don't even consider them in any calcs because they're such a small amount by weight.

Yes. I weighed out 1/2 lb.

What I've been doing when using rice hulls i sputting them in my mash tun (cooler) with the pre-heat water, swishing that all around and draining it out through the valve, I've then got preheated presoaked rice hulls, so I don't figure them into my water calculations at all.

I've never weighed mine. Austin Homebrew Supply sells them in 1# bags, so I just use 1/2 a bag.

I guess I have another question. Do rice hulls have the same/ similar tannins as barley hulls? My friend kept poking the grains while we were doing the lauter (I was not present). And when I started the boil there was a plethora of rice hulls that started surfacing!! Am I screwed?! More like, he's screwed because this beer is for his wedding.

Everyone has their own method with these... to rinse or not to rinse, to soak or not to soak... etc etc.

Personally, I think its a waste of time to rinse/soak the hulls. The amount of wort they could potentially absorb is microscopic anyway. Just add a couple of scoops---no need to weigh them out. If you're making a hefe by traditional German stardards, maybe youll want to add a little bit more. Most likely a couple of scoops and youll be fine.

What is your set-up for the sparge?
