Up until yesterday, I've been using a brewing calculator for my strike and sparge water calculations. I usually ended up with about 8 gallons of preboil wort with my method which consisted of 3-4 gallons of strike water and 5-6 gallons of sparge water, depending on recipe. I would never try and split strike and sparge water 50/50 (like your method). Usually, my way had great efficiencies but my gravity would be a few points low. Your way, yesterday, gave me a more accurate OG. Did that make the difference?

I can't say for sure, but it's entirely possible it did. You'd need to repeat exactly the same batch and procedure a few times to be certain, though.

If I perfect your method, I'm starting to wonder if I can pull off 10 gallon batches in my 52qt mash tun.

Hi Denny,
I have a question regarding your article on batch sparging. I have been fly sparging and anything to cut the time down on brew day would be great. My mash tun is a 10 gallon pot with a false bottom. The false bottom takes 1.25 gallons to fill. If I use this set up to batch sparge how do I account for the extra water in the false bottom. It seems most people batch sparging use a mesh screen instead of a false bottom.
bonjour:
I batch sparge a bit differently, and I don't calculate.
1. mash normally
2. drain mash tun into boil kettle (after clearing the wort/vorlaufing)
3. measure the wort in the kettle
4. add either the full amount remaining or half the amount remaining
5. repeat as necessary from item 2.
Works every time and no worry about dead space.

Boy, that's one I haven't dealt with! I assume you;d account for it the same way you do for fly sparging. Is there much dead space or does it drain completely?
