I've got several Cambro buckets that I use for my batch cooking: a couple of 7 quart, a couple of 3 gallon, and one five gallon (22 qt). I got real familiar with them when I managed a Luby's cafeteria! I love them due to the fact they are professional grade food service containers and can be easily cleaned. Mine are the "white" buckets but I've used the clear poly containers, too. They get a lot of use cleaining bottles, storing StarSan, bottling buckets, etc. Im getting ready to invest in a couple to use as primary fermenters for 5 gallon batches. Currently I use some snap-top Rubbermaid food grade containers for my 1 gallon primaries - they are 6 quart so I've got plenty of headspace for that initial activity. I drilled 1/2 inch holes and fitted them with grommets for the airlocks and/or blow off tube.
