This carboy is REALLY old, I'm not sure how old though. I've checked it a couple times. When I checked it it was 4.5 gallons when filled to point where it starts curve at the top so it could be 5 gallons.
I've also got a plastic carboy from when I had a water cooler and it's 5 gallons but it says water only on it.
