I want to put together a partial mash by mashing oats and minute rice and then sorghum LME. However, since I'm not sure of the fermentability of the oats and rice, I'm going to have to fly by the seat of my pants here.
I do stovetop PM's via the BYO magazine 2-gallon cooler method, but I use a pair of coolers so I have the ability to mash up to 8 pounds of grain. So my plan is to mash 3 lbs of oats and 5 lbs of rice, boil that down for about 30 minutes with a little bit of hops, check my gravity, and add the sorghum needed to get to 1.050.
Using Brewtarget, here's the recipe I've come up with. To anyone with experience mashing GF grains, does this sound solid?
5 gallon recipe
3 lbs GF oats
5 lbs minute rice
Mash 1 hr 154 degrees
Sparge 5 minutes 165 degrees
Preboil vol. 3.65 gal
45 minute boil, ending boil volume 3 gallons
2 lbs sorghum LME, late addition
Hops:
1/2 oz Simcoe leaf (13%AA), 45 min
1/4 oz Simcoe leaf, 15 min
1/4 oz Simcoe leaf, 5 min
Yeast: US 05
2 gal top-off water into fermenter.
Ferment at 61 until ready for bottling.
Target OG 1.051
Target FG 1.013
ABV 5%
22.8 IBU
5.6 SRM
I would likely add some spices (orange zest, star anise, coriander, pepper) which I put in a Belgian Blonde recently with good success. Also yeast nutrient with 5 min left in the boil.
Any advice? Anything else need to be added to the mash? Is 154 an appropriate mash temperature? I think that is my single biggest question.
Thanks for the help.
