The #1 Question I hear about Mash Tun N00bs is HOW MUCH GRAIN WILL FIT IN MY MLT?
My question is a polar opposite.
I'm looking at a 48 Qt Cube, and I'm thinking that I can not get a deep enough grain bed with my typical 8 or 9 pound grain bill, unless I do 10 gallon batches, or Imperialize EVERYTHING.

So My question to you, what is the smallest grain bill you mash in a big cooler?

I am sure I'll be the guy with 2 or 3 mash tuns for different grain bills, but for now, I'd like to not screw up a batch....or get worse efficiency than normal.

Are you batch sparging? I think the depth of the grain bed is not nearly as important with batch sparging compared to fly.

I use 10 gallon cylindricals, so I'm afraid I'm not much more help

Yes, I do Batch Sparge.
Currently I'm using a 5 gallon round cooler, and I am using about 4 to 4.5 gallons of capacity.

I have both, 5 gallon cylinder and the big cube. If the mash volume is close to 4.5 gallons I use the cube.

So i guess my answer to you would be anything thats bigger than 4.5 gallons. Not much help huh?

No, not a lot of help, but somewhat verifying my plan to have 2 mash tuns, and use them as appropriate. Same with boil pots?

If you're batch sparging the grain bed thickness is not nearly as important. I'd say your plan to use whichever MLT is appropriate makes a lot of sense to me if you don't mind having duplicate equipment.

As for boil pots, are you asking if you should have two different sizes for different size boils? Because I don't think it makes any difference if you boil the same amount in a larger vessel.

I have a 9 gallon pot for my 5 gallon batches and a 5 gallon pot for my 2.5 gallon batches. I only do the 2.5 gallon batches to experiment and tweaking and sometimes just to brew variety, otherwise known as playing!!!!!!!

I've got a 48qt cube and haven't had any problems....I batch sparge as well. Most of my 5gal recipes are around 10lb of grain if that helps any....

Green Bay Rackers--Mash Calculators

Towards the bottom is a mash tun calculator. It calculates the volume you'll need to mash.

Yup Totally aware of that.
The question is: How SMALL of a grain bill do you use in a big mash tun. I am not worried, nor asking about capacity, I'm worried about ending up with less than 1/3 of the mash tuns vertical capacity, and having a hard time with dead space or efficiency.
