So how big of a MLT do I need to shoot for if I want to do 10 gal batches of all grain? I realized the grain bill has an impact, but is a 5gal cooler enough? Or should I just step up to the 10gal round cooler?
I need to work on my brewing to drinking ratio. My production has not been keep pace with demand.
For 10 gallon batches, definitely 10 gallon cooler, especially if you are going to brew anything with a larger grain bill. Mashing 20 lbs of grain using 1.25 qt/lb requires 6.25 gallon of strike water without considering grain absorption.

Pigs are fantastic creatures. They convert vegetables into bacon.
If you are considering 10 gallon batches, certainly a 10 gallon, maybe even 12 if you think you might ramp up even more in the future. I have a 12 gallon rectangle because i already owned it. If I were buying new I'd go with a round one.
