Default min size for 16 gallon ferment?

would a 20 gallon vessle (e.g. brute trash can) be adequate for 16 gallons of wort or would i have crazy blow-out?

i can get the 30, but if the 20 should be okay, i'd rather go with the smaller size.

thanks!!

If you can control the temperature, it should be fine.

20 should be fine, I usually go with 20% freeboard on the fermenter and have a few messes but nothing substantial.

I've heard you want at least 30% headspace, so on a 16 gallon ferment, that would be 20.8 gallons. 20 should be fine.

20%? 30%? Where do these numbers come from?

Before I had a way to control temps, I had blowoffs that would have needed 100% head space to contain it, but now it's not an issue.

I read it in one of the homebrewing books...not sure which one now, because I've read about every one available

It also depends on the yeast. 3068 will make a mess at 30% headspace and a lager yeast would be fine at 10% if it was at the proper temp.

Do you put a liner in the trash can or ferment right in it?

Use fermcap! There'd be no way you'd have blow off
