Question about the size of a carboy.

I'm thinking about making a few half batches of lagers because I have a small refrigerator that I might be able to use for fermentation and lagering.

I have a limited headspace in it so if anyone has a 3 gallon carboy lying around and wouldn't mind measuring its diameter and its height I'd really appreciate it.

I don't mean to be a jerk... but no help at all?

Could be nobody has anything that size. If you still don't have a reply in the morning, give it a bump again so it's on the new posts screen during the business day (don't worry, nobody will flame you or anything!).

Okay... thanks for the tip. Worst comes to worst I guess I could just PM the guy from Austin Homebrew since that's where I'll probably be purchasing from anyway.

Good question. I don't have an answer but have you looked at the 3 gallon better bottles?

I have two tips that might help you out:

First, try posing your question on the mead board. You'll find more there that use three gallon carboys. Most brewers don't use them. Unless I start making meads, I doubt I'll ever own one.

Second, give it more than three hours from the time you pose your question until the time you post impatient responses to yourself. This is an active forum, but don't expect that anyone just sits around all night waiting for questions to answer.


TL

I have a 3-gallon carboy at the house, I'll measure it when I get home if no one else responds with the answer.

I think I also still have one. I'll check in the evening...

Here are the spec's for a 3 gallon Better Bottle off of their website:

Design:
Overall – 19 cm (7.5") square 49.1 cm (19 1/3") high
Neck – ID 45 mm (1.77") / OD 55 mm crown
Volume – Nominal 3 US Gallons (11.4 liters) [ filled to bottom of neck ~11.6 liters]
Weight – ~0.68 Kg (~1.5 lbs) empty and ~12.1 Kg (~26.6 lbs) filled
Pressure/Vacuum Limits – 0.14 bar (2 psi) and -0.05 bar (-0.75 psi) at 25° C (77° F) – Though very sturdy, this square carboy is not designed for significant positive or negative pressures.
Temperature Limits – -30 to 60°C (-22 to 140°F)

I am still looking for the glass carboy dimensions.

Cheers

Found this on eBrew:

3 Gallon Glass Carboy
Height = 16.5"
Diameter = 10"
Height with AIRLOCK attached = 22.75"

Not sure if the airlock would really add six inches to the hight, but you could just measure your airlock to find out the height difference.

Just measured my 3 gal glass carboy.
Height is 16.5"
diameter is closer to 9" than 10"
circumference is ~28.75"

Stopper and 3 peice airlock adds 3.5-4"

Thanks everybody!
