Being out of room in the tun is justification enough.  Just curious.

I was just playing, Denny.
I find that humorous outbursts make my day more interesting.

Very seldom, and only on the case you mention....I'm using so much grain that I can't fit all the sparge water in in one go.  Other than that, there's no point I can see.

I don't have a good reason, but I always double batch sparge, regardless of whether there's room for a single.
I guess it's habit.

If you enjoy it, good on ya.  For me, doing what I see as needless effort drives me crazy.

So if double batch sparge do I divide up the water?
1/3 mash, 1/3 sparge, 1/3 sparge
or
1/2 mash, 1/4 sparge, 1/4 saprge

Either way, although if 1/3 of the water puts you in a good mash ratio then you'll get better extraction from having two larger sparges.

Having said that, I generally use as much water as possible for my mash, and only sparge with what won't fit.  With my MLT I can do up to 3.5qt/lb so I'll only have a gallon left for sparge.  Its more like no-sparge this way, but I still get my usual 75% efficiency.

I usually figure 1.25 to 1.5 qts per lb for mash, & then split the volume that I need to cover:
Boil-off + trub losses + grain absorption + dead space.

(I let Beersmith do the math.)

The only concern is your mash pH during runoff. In an effort to avoid tannin extraction you will need to monitor and maintain your mash pH < 6.0 during runoff. You can always make a small addition of phosphoric acid if need be.

I thought pH wasn't an issue with batch spargng? I thought the tannin thing was from over spaging?
And if I had money for a pH meter I'd use it buy a bigger mash tun.  ;D

pH is critical to mashing and overall beer flavor. Tannin extraction occurs at a pH > 6.0. It's usually not a problem when batch sparging, but again it depends on your water profile and you grist.

It's the reason I went away from the 5 gallon round and use the bigger rectangle cooler or 10 gallon round or my keg with false bottom.  I rarely run into the issue anymore and plan my bigger beers for the bigger units.   But I add as I go up to half total volume and then same with the second half when absolutely necessary.  You guys that go big all the time have these problems more frequently than me with my little brews...

Brewed this up yesterday.
I just gently added the extra water as I drained the mash tun.
Wound up with 80% efficiency.
No problem.
