Rice Hulls

Unread post by Bigstew »

At the weekend my plan is to do a clone of Shepherd and Neame Bishops finger, the clone brews book calls for 227gm of rice hulls to prevent a stuck mash. As they impart zero in colour,flavour etc is there any point in putting them in because of the way the BM works. Or any equivalents I could use please.

Don't bother - they are totally unnecessary.

Depending on what you brew, they are necessary. I just brewed a Witbeir on my BM and used 5kg of flaked unmalted wheat and 500g of flaked oats, as well as 5.5kg of pilsner malt. I used 600g of rice hulls with it to prevent a gelatinous mash. It all worked well in my 50L BM and I got an 87% mash efficiency. I tried the same recipe in my BM once before without the rice hulls and the mash set like jelly.

A good substitute for rice hulls are oat husks: https://www.themaltmiller.co.uk/product/oat-husks/.

Better safe than sorry!! I was doing a bourbon (70% corn maise) on the weekend and it was like jelly when I pulled the grain out and during the rests at times it was shooting water spouts. Was a little funny until I seen about 500ml of my wash on the bench. Was definitely wishing I had used some rice hulls..... lesson learnt as I will be next time! :oops:

I've done corn in a normal mashtun and it would have to be the hardest grain to work with, turns to a porridge(think polenta)
I'm not sure if rice hulls would be much benefit.

I re-run the same grains last night, still with the 70% corn maise but this time added 250gms of rice hulls and it went flawlessly thank god. I wasn’t sure if the rice hulls would really do you much but it even sparged well. So (for me at least) they worked a treat, good enough for me to do the same next weekend hoping for the same result as I just got last night.

@azagill, spurts are wort fountains.
Look up malt conditioning (broken record, me)

I don't know whether rice frames would be much advantage.

I just prepared a Witbeir on my BM and utilized 7kg of chipped unmalted wheat and 700g of chipped oats, and also 7.5kg of pilsner malt. I utilized 800g of rice structures with it to keep a thick squash. Everything functioned admirably
