Not Very Useful
I purchased this to use as primary fermentor for small batches. Unfortunately, the 3 gallons volume is to the very top lip of jug. Could ferment maybe a 2 gallon batch, but still get lots of overflow when the wort is really churning.
Probably only useful as a secondary and then only for 11 quarts or less.
Hard to clean the square corners, especially at the top.

Good but not great
Purchased 3 gallon better bottle to get away from fermenting in plastic buckets. I am brewing 2.5 gallon batches normally. Have used it once and it worked well. If I get another I will definitely buy the ported version. I bought this one and drilled a port in it (I purchased the racking tube and spigot separately) and adding the port was a painfully delicate process. Cleaning was okay with PBW but I still felt like there was residue from the krausen so I GENTLY cleaned with a carboy brush. The fact that every single accessory is sold separately is annoying. The best advantage of these to me is the ability to rack without siphoning. That worked spectacularly.

Nice for Small Batch
I am using this as a Secondary Fermentor and can end up with 2.75 gallons or 10 L. Easy to use & clean.

Max Vol = 3.065 Gallons up to within 1" of top.
Siphon Loss:
0.4 G from top of dome at ctr - use this for Primary
0.1 G from corner - use this for Secondary

Nice to have - Volume markings.

what is the highest temperature that liquid can be transferred into the fermenter at?
A shopper on Feb 15, 2018
BEST ANSWER: Ask the manufacturer to be sure, but 140F is a good general rule for "plastic" carboys. I never transfer any wort into a carboy/fermenter until it's close to pitching temperature (<85F) so this is not an issue for me. I have my hot water heater set at 120F max. After kegging, I put a tablespoon of Oxyclean in the carboy and then and then fill it to overflowing with hot water. I let it soak overnight and the gunk rinses out with cold water the next day; no scrubbing or effort.
What are the dimensions of this product?
B A on Aug 26, 2016
BEST ANSWER: It is about 7" x 7" and about 19" tall without the airlock.
