I did the extract batch first. Steeping the grains and bringing the extract batch to a boil took about an hour. About ten minutes into the 60 minute boil, I started heating up the strike water for the AG batch. (Yep, you need two buners to make this work). Did the 75 minute mash while the boil and chill for the extract batch were on, and then heated up the sparge water while whirlpoolling the extract batch.

As soon as I poured the extract batch out of the kettle and into the fermenter, I gave the kettle a quick rinse and drained the mash tun and proceeded with the AG batch as usual. Like I said above, 100% more beer for about 20% more effort. Cheers!
What batch size? It takes me 6 hours to do a 10 gallon AG batch. Fly sparging takes a while, and I usually do 90 minute boils.

So that's either 2 5-gallon batches and one small batch (beer #3) in one shortened brewday, or if you're willing to add extract to the smaller boil, you could top beer#3 off with a little water and turn it into another 5-gallon batch.

Two weekends this month I did back to back ag 10gal batches and currently have 40 gals fermenting and cleaning up. Had to buy some more fermentors but with the cold weather temp control is easy as setting them in the basement. Id have to say if your really organized it only added 1.5 hrs to my brewday. Seems like a no brained when you have gone through all the set up work as it is. The only problem has been the the short winter days I hate wrapping things up in the dark.
