3 Gallon Better Bottle™

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.

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.

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

Stats:
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.
