That says I likely have a 7.5gal... 12" wide though, I guess I could be off in my estimate. Well, time will tell... and a 1 gallon jug.

Those are the exact dimensions of my 6.5g carboy. I'm sure the actual total volume of the carboy on ebay is close to 7.5 gallons, but I think the volume on carboys is considered net. At least, on the bottom of my 6.5 gallon IIRC it said 6.5g net.

2002 is the year of manufacture. The only way to really tell how big it is is to measure the volume of water going into it.

I'd put money on it being the 6.5 gallon carboy that everybody knows and loves. I've never measured mine out, but recall someone else saying they can get at least 7 gallons in one.

Haha, haven't gotten any pictures yet, sorry guys, but I did take some measurements. Its 12-13" wide and its 20.5" tall. The 5 gallons of beer in there come to 3" below the shoulder, and the shoulder is 12" from the base. Therefore there is 9" of height to 5 gallons, or just shy of 2" per gallon. That tells me that I could fit 6.5 gallons in and be just under the shoulder. So, either fermenters are measured such that the gallon measurement is obtained from how much liquid it takes to come to the shoulder, OR its a 7.5gal fermenter with the shoulder-up space taking 1 more gallon of liquid. I would believe its the former, and its a 6.5 because there would be no point to filling it up to the neck. Logically, a 6.5gal fermenter would ferment 6.5 gallons of liquid with headspace for the ferment not counted in the capacity of the vessel.

So, for future reference, a 6.5gal fermenter is about 12.5" wide and 20.5" tall.

What threw me was that I thought the 5gal carboys were 12" at the base, they are not. They are actually closer to 9.5" diameter at the base, as I measured one sitting next to it to come up with the measurements.
