Fermenter Head Space

[kvh]

This answer probably already exists elsewhere, so forgive me in advance.

So I'm considering attempting my first All Grain. I don't have the set-up yet to make a 5 Gal. batch, so I think I'll try my hand at 3 Gal.

Without purchasing extra equipment, should I be worried about the added headspace in my fermentor if it's only 3/5ths full, or will that room fill with CO2 and not be an issue?

Thx.

There is no reason for concern, in fact with all grain you could make 3.5 or 4 gallons and still be good.

Right - I have two 5-gal buckets and two 5 gal carboys. The issue isn't the fermentor, it's the size of my stockpot... 5.5 gal, and a still white kitchen stove to cook on.. I don't want to boil over if I can avoid it.

Thanks!

The headspace is fine in the fermenter. It will fill with CO2 and you'll be set. My barleywines have been 3 gallon brews in my 6.5 gallon primaries.
