2G Fermenter

Product: 40-41800-00

Availability: Out of stock


This unique, patented brewing system is completely reusable and is comprised of 4 parts; our high capacity fermenter, Krausen Kollar, lid, and Snap Tap. This vessel will make 1 case of award winning beer with every batch. The Krausen Kollar adds that extra head space for your bigger brews while also minimizing yeast carryover, dramatically reducing cleaning time. The Snap Tap separates for easy cleaning as well. This vessel and its parts are designed to industry leading standards and made of durable BPA free plastic that is UV-resistant, dishwasher safe and imparts zero flavor to the beer.

It is highly recommended you purchase the bottling wand accessory to use with this fermenter. It is not required, but it is very helpful and reduces oxidation!

Rated 5 out of 5 by from Best fermenter I purchased this fermenter about a year ago. I love the upright design. This makes it easier to use for brewing. Bottling is great ! Will never use the Little brown barrell again. Would recommend to start with the 2G fermenter.

Rated 5 out of 5 by from Easy to Use I waited until this fermenter was available by itself to purchase it even though I liked the design from its introduction as a kit. Great way to brew! As others have said it's easier to clean but I also like the extra headroom for slightly larger batches or more active fermentations. The collar helps keep the brew cleaner and I like how the spigot easliy snaps open & closed. The footprint of this fermenter is much smaller than the LBK so it can stand in a tigher space. Two negatives are that I found it very difficult to insert the wand into the spigot and with the tallness of the unit could not fill it with water from the tap, but instead had to fill with a pitcher. But the wide opening on top does make it easy to fill and add any mid-fermentation items.

Rated 4 out of 5 by from 2 gal Brewmaster. I'm happy with this product. I bought it because I thought it would be an upgrade to my little brown keg. It works fine, especially with beers with high krausens. While it is easier to clean than the little brown kegs, I'm always spilling the wash everywhere. I find that I use my little brown kegs more often, because they seem less awkward.

Rated 5 out of 5 by from Upgrade. Bought this fermenter as an diction to my little brown barrel butt eventually I think Inwill be replacing the little brown barrel with another one of these. I like to have two 2 gallon batches going about a week apart, that way I can try different recipes, without being stuck with 5+ gallons of a brew I don't like. My system is working out great I give a consistent flow of different brews. The Krause collar included is a nice touch too, makes cleanup much easier.

Rated 5 out of 5 by from Very easy to clean! I got this to replace on old keg type fnerminter. This is very easy to clean and sanitize and use. Only drawback is the spigot is large and it is impossible to fill a bottle unless you have a dispensing tube (that mine didn't come with)! I had to make one from tubing to bo,title my first batch, witch was (That Voodoo that you do)! This is a very good mellow beer that all my friends love and some are going to get a fermenter and start brewing too!

Rated 5 out of 5 by from The size is small but accurate I use to have the bigger size but its heavy and difficult to handle it however now with the smaller size it's just right size and enough to brew.

Rated 5 out of 5 by from Love it! I bought this to make the Big Red One brew. This makes brewing and cleaning so much easier.
