Ideal size of glass carboy for primary?

[bmickey]

I went and bought a 6 gallon carboy and 1" diameter blowoff tubing. Now I'm wondering if I should return it and get a 6.5 gallon.

Hefe's are my favorite style beer. The only other beer I've brewed that is close to a high gravity would be a arrogant bastard clone which I'll do again.

Right now I'm fermenting in 6.5 gallon ale plastic buckets but just trying to upgrade my equipment and processes a little.

6 gallon with a blow off tube is fine

take it back, the first time the extra 0.5 gallons of space comes in handy and you dont have to clean the big bad blow off tube it has paid for itself.

I agree with homey but I only use a 5 gallon fermenter... why? My kettle isn't large enough so I don't get a full 5 gallons of wort. So, it depends.

[Bugeater]

The rule of thumb for fermenter size is your wort size plus 25%. So 5 gallons plus 1.25 gallons = 6.25 gallons. 6.5 gallons is on the safe size. If you brew a lot of hefeweissens, you won't regret the extra half gallon. You will waste a lot less beer to blowoff.

+1 to Bugeater...i don't even like using my 6 gal but it works. i wouldn't go any less than 6

I've used both with success, I've just gotten into the practice of putting a blow off tube on everything. Ideally I'll use the 6.5 gallon if I can, but no negative effects from 6 gallon primaries.
