  • Works great so far
Product arrived undamaged in shipment with all required parts. I started a mead on the same day and it's been fermenting for three days so far. No signs of leaks near the spigot (the instructions helped explain the assembly and urged to check for leaks before use). The legs were easy to assemble and despite their size seem to handle the weight of the must very easily. Looking to handle primary fermentation in this one and transfer the ~1-gallon batches for adding fruit and backsweetening later. The vessel is pretty thick for as light as it is. About as thick as a normal Tupperware bowl, but the bottom (cone shaped) part is much thicker and the thickness sort of tapers off as you near the lid. The spigot assembly can seemingly be replaced for about 3.00 USD, but seems pretty solid. The spout fits right into my 1/2 inch (inner diameter) transfer tubing pretty snug--so much I had to hold the spout while removing the tube in fear of bending the spigot accidentally. I really like the adhesive thermometer. Very simple but effective. The wide mouth made it much easier to reach in for deep cleaning before use. One small concern I had was attempting to slide the vessel into the rack while the spigot is attached, I had to tilt the entire vessel slightly to ensure the spigot didn't catch on the rack and bend it accidentally, although I'm not sure there is really anything that can be done to address it. Another mild concern is the included pamphlet showcasing the design and included parts lists the container as a 3-gallon vessel. This can likely hold three gallons but leaves almost no head space, and I purchased 3-gallons of water along with enough honey for a 3-gallon batch, which left me adding more honey than I originally intended. There are raised markings on the rear of the vessel noting these measurements. Overall, I'm extremely satisfied with the product and excited to see how this batch goes. ... show more

  • Works well
For various reasons, I don't always want to use my 6 gallon fermenter. This fits the bill for smaller batches. Easy assembly, no leaks and good beer. I'm happy with the purchase!

  • Cheap but (and) good!
Other reports show that this is a very cheap design. Yes, it is, but it works very well. Yes, you can break it easily, but if you are careful, it works just like the $200 conical. I like it, because you can experiment with smaller batches. I now have 3 of them, all in production. And yeast harvesting works just fine without a ball. ... show more

  • DO NOT BUY!
Cheap plastic garbage, I cannot recommend this as a fermenter- the idea itself is genius, but the product itself is cheap and poorly made. This all plastic set up is poorly molded, the pieces barely fit together and the fermenter itself is not air tight. The site advertises that they are using some kind of fancy(proprietary air lock system) but that's just false, even when using the bubbler conversion the lid doesn't seal tightly enough. This is a temu quality item they are overcharging for. This kit all together isn't worth more than $15. The customer service is completely non existent as well. Be warned that returning this will be a nightmare as Amazon just forwards you to brewdemons customer service, which again doesn't exist. I'm currently 5 days into an email conversation with them about getting a gasket replaced, now I'm just trying to return it. Trust me, for your money just buy something else. Glass fermenters here on Amazon are pretty decent and a fraction of the price... ... show more

  • Clever product & top notch customer service
The conical shape of the fermentor is ingenious. The sediment collects there. Plus the stand and spigot allow for easy bottling in the sink, letting the natural flow of gravity replace the syphon. As for customer service, they are over the top. Responsive, timely and very enthusiastic about answering our questions. Couldn’t ask for more! ... show more

  • Turned out to be quite a nice little fermenter.
Had been looking for a small 2.5 gallon fermenter (aside from my old 3 gallon bucket) to experiment with some recipes when I saw this one. Honestly, I was kind of kind of skeptical at first but so far, after several batches, it's worked great. I threw away that red little "air-lock" button that came with right from the get-go and just use a regular bubbler / stopper. Also, a few reviewers complaining about the lid not sealing but on the first and second use i had no issues with it. The third time, I noticed I wasn't getting as much air-lock activity so I took a piece of saran wrap doubled it over and spritzed it with starsan. Then spread it on top of the opening and carefully screwed the lid back down snug over it. Worked like a charm. Air-lock was back to bubbling full force. Been using it like that ever since. I haven't had to buy any of the lid gaskets so far as the wrap seals the lid fine. There are volume marks embossed into the wall but you can barely make them out. I went over them with a sharpie. Valve works fine so far, no leaks. No problems draining it to 2.5 kegs. I do wish they had added a yeast dump into the bottom of this one to make harvesting / rinsing easier but, meh...All in all, it's not a bad little fermenter and works as it's supposed to. When it does finally "die" I'd buy another. Personally, I like it better than using the 3 gallon white bucket, though I guess you could use the 3 gallon as a primary then rack into this as a secondary. Was shipped on time and came on schedule. Came in its product box inside a second larger well packed box. ... show more

  • VERY Handy
This thing does 2 and a half gallons of hard cider in 10-14 days and clean-up is quick and easy. No need to "rack" because of the conical shape AND if you want to, you can re-use the drub at the bottom for a next batch instead of adding new yeast. Very nice. I don't use anything else anymore.

  • What’s more to know about the brew demon fermentation vessel?
Great for both primary and secondary fermentation purposes. I wish there were some glass options for long term aging.
