OK, I promised these results, and here they are. I made a Budweiser-style beer this weekend. 10 gallon batch.

I boiled 4 gal water with 5# rice for 10 min (in the bag, would do 20 min next time), added about 3 gal cool water down to strike temp and stirred in barley.

Mashed in at 157*, put the lid on and went to my wife's brother's baby shower. Dudes in one building and girls in another. Weak, I know, don't get me started. BUT I caught two serious sized largemouth on a frog lure in the lake behind his house, so it wasn't too bad :)

Came home 4+ hours later and heated to mash out at 168.

Pour over sparged ~7 gals (@150ish degrees, all I had). Poured 1 gal, let it drain a little, poured another, etc. Took about 10min total.

Boiled 75 mins by timing accident (forgot 2nd hop addition and whirlfloc until too late).

Chilled using a pump and the r/o waste water through an immersion coil chiller, down to 70*. Pitched s04 slurry and into chiller.

After all, I UNDER sparged about 1.5 gallons, and ended up with 10 gallons even (after leaving the whirlpool cone behind) in the fermenters (and I usually shoot for 11 gals/5.5 in each).

86% efficiency and clear, sweet wort. I have gotten 81 -88% efficiency on this recipe in the past, and with 1-1.5 gallons undersparged I'd guess I maxed out my efficiency.

I am now a pour over sparge BIAB brewer.

Might have something to do with the super long mash. Did you happen to measure the mash temp after you got back home?
 
Yeah. This recipe normally uses a 4 hour mash to get a dry finished product.

It's a variation I've developed over the years that was inspired by Shlenkerla's lite beer recipe, but I jacked up the flavor and complexity a bit.

I'm just stoked that I got basically the same results this time with a pour over sparge that I used to get with a double batch sparge... makes things a lot easier!
