Guess the bag would sit in the strainer because of the big holes. Sure wouldn't want to be the one picking that friggin heavy bag up when it's full of that much wet grain. My back hurts just thinking about it.
Edit: Course, my dumb arse didn't quite read that right. I assumed you were saying someone would do 30 gallon batches in it.....that would be alot of grain. Guess someone could do alot less...lol
