Chocolate Oatmeal Stout

Today I did my first recipe with oatmeal, and a significant amount of oatmeal as well, 3# in the grist. I used 8 cups of rice hulls, but the sparge was still very sticky. Thankfully I had an assistant today, or it would have been very slow work.

I used my small pot to move the mash over after an hour, and that went very well. It seemed to be draining very well, until I got to the second batch sparge. Then the mash became like paste.

We got through it with a lot of stirring, I have to be honest and say that the sactity of the mash bed was not respected at all in this session, and suction was the #1 enemy. The sparge took at least an hour, which allowed for plenty of time to enjoy a homebrew.
When the sparge was finished, or abandoned, I had about 9 gallons of wort. Then we began a very careful boildown, as the boil vessel was pretty much at capacity.

Once we got to the transfer, it was smooth siphoning. A beautiful chocolate colored wort ran through the tubing, and I ended up with a lot of wort at the end of the boil.

I transferred about 6 gallons of wort into my 6.5 Gal carboy. I’m trying some fermcap in this batch to see if I can avoid a blowoff, I’d really like to keep as much of this brew as possible.
