I want to find a container for bulk fermenting 2000g or 4000g of dough for either 2 or 4 loaves.
What size containers should I get?
I use a 6 at bucket like one below. I think it's good for around 3000 grams but you may be able to stretch it to 4000 if you don't expect a lot if rising.
Here’s a pic of 2400 g dough in flight. Would easily work with 4 kg.
