Back in '99, when this little keg was introduced, Mr. Beer had no idea just how much it would impact the future of homebrewing. It has affectionately been dubbed the LBK, or "Little Brown Keg," by its followers... and there are plenty of followers out there! Mr. Beer has shipped over 2 million of these fermenters around the globe in an ever-increasing rate as the proliferation of homebrewing continues.

Each LBK is a completely reusable designed fermenter which minimizes yeast transfer and has a unique venting system. The LBK makes 2 gallons of award-winning beer every time you brew. Since it is not made of glass, this fermenter is lightweight and can withstand much more abuse than your typical glass carboy. No need to worry about dropping this little guy! The LBK is made from an industry leading and durable BPA and phalalate free plastic that imparts zero flavor to the beer.


  • 1 Brown Fermenter *New and Improved Wide Mouth for better cleaning!

2 Gallon Fermenter is rated 4.2 out of 5 by 46.
Rated 5 out of 5 by from LBK Still the best brew keg I have been brewing MRBeer for 5 years. I have brewed 'others' as well as build my own recipe. I have 4 LBKs in the brew schedule. I try to replace one keg each year. I save the old LBK for use as a batch prime bottling bucket- (easy) and to store cleaner/sanitizer . The only problem I had was the twist spigot. I prefer the old lock style. I found them from another source. Never had any problems with the LBK. I keep the kegs filled with Star-San mix when not used for brewing. I tried a different style of brew keg, but it was larger then I could fit in the fermentation chamber. I prefer the MRBeer LBK . Get a new one when on sale

Rated 5 out of 5 by from Great for home craft brewing My son and I have brewed at least 20 batches with Mr Beer kegs, we have three of them. There is nothing wrong with using the kits, but we have a brew supply store nearby. We build our own recipes selecting flavor grains, LME, hops, and yeast at the store. You can get lots of recipe ideas on line from everything to hops and yeast profiles to recipes to clone your favorite beer. Just keep in mind that most of the recipes on line are for 5 gallon batches and adjust. A Mr Beer Keg batch will make about a case of 12oz beer bottles and take about a month from boil to conditioned. 2 weeks fermenting, no secondary, 2 weeks bottle conditioning, a couple days in the fridge. Sometimes letting the bottles sit a little longer makes it better.

Rated 4 out of 5 by from Great fermenter for small batches I like to devise my own recipes, and this small keg fermenter is easy to clean, isn't bulky, and looks cute on the counter. Invites comments and questions, and its dark brown color prevents the "sludge" from being the main conversation point (as in, eeew, you'd drink that?). Although MrBeer seems to believe that plastic is a good selling point, I wish they'd sell it in glass. Glass is easier to keep sterile, can take hot liquids better, and I could wash it in the dishwasher as an added sterilization step. The plastic is very thin and easily damaged, scratched, or deformed. At least they've decided to make it with BPA free plastic.

Rated 5 out of 5 by from Standard Refill keg beer My wife bought me this kit for Christmas. Never brewed beer in my life, so my first attempt did not go will. You know that saying “try, try again. The second attempt will let me just say it was drinkable. I just needed to fine tune what I was creating. After several emails and some great info from the help desk. My 3rd try was an October Fest and let me tell you it was outstanding, the taste and body was was fantastic. I was hooked. I have brewed several more (OF), a St. Paddy’s, which I just bottled and Chez that will be bottled on Tuesday. If you are just starting out don’t get disappointed if the first batch doesn’t turn out, just keep trying and call the help desk those people know what they are talking about. Thank you help desk.

Rated 5 out of 5 by from Great product!! I bought my first Mr. Beer kit back in 2009. I liked it so much and the ease of the fermenter I had to get a 2 one so I could brew 2 different beers at once and keep my beer supply stocked up at all times. I am definitely looking to up grade to the 5 gallon kit to brew some big batches of my favorite beers at once and will use the smaller barrels to experiment with smaller batches and make my limited select brews in. This product is a great fermenter and easy to use without all the fuse.

Rated 4 out of 5 by from MrBeer Kit Makes It Very Easy to Brew Your Own Beer I received a MrBeer Kit for fathers day. I wasn't thrilled that it had American light beer in it. I'm not a fan of light beer, you might as well drink water. I was very impressed with the flavor and was very hoppy with it . My softball team enjoyed it too, I shared it with them after a game. There is nothing like a nice cold beer after the game. The kit makes it very simple to brew your own beer. I ordered another 2 gallon fermenter, and I'm in the process of brewing American Lager and Winter Dark Ale. I can't wait for it to be done in a couple of weeks.

Rated 2 out of 5 by from Slow leak fixed My fermenter had a slow leak at the spigot which I traced to a rough seam. Maybe the keg could be molded in upper/lower halves so there is no seam at the spigot? Anyway, I ground down the problem area and now no leaks.

Rated 1 out of 5 by from Poor construction Bought due to great reviews. First one had a crack in it. Second one has a deformed mouth. Hopeful for the third one.
