1 Gallon Glass Fermenter

Product: 20-21000-00

Availability: In stock


Welcome the first Mr. Beer fermenter to be offered in glass, and now our smallest fermenter, to the Mr.Beer fermenter line-up! Brewing small batches will mean fresh, new beers that get cycled through quickly. You'll have just enough room to experiment with recipes. Small also means easy to store.

Watch your beer ferment through the glass, and get familiar with the signs of healthy fermentation. Since this is not the usual glass carboy, you'll also save yourself the trouble of siphoning.

When you are finished with a batch, cleaning will be simple with this fermenter's wide mouth.

1 Gallon Glass Fermenter is rated 4.0 out of 5 by 4.
Rated 4 out of 5 by from Nice little fermenter for the price. I bought two of these so I could keep a rotation of small batches going. The airlock that comes with the fermenter is very low quality, so plan on buying a .965 rubber bung and decent air lock. I have had no issues with bottling as mentioned in other reviews. A 1/2” bottling wand and hose works just fine with the supplied spigot if you use a hose clamp on the spigot side.

Rated 4 out of 5 by from Pretty good fermenters for 1 gallon batches I bought two of these fermenters to allow me to do small batches and easily bottle them instead of using my 5 gallon equipment and kegs. I filled them both up with wort yesterday and I'm pretty happy with them so far. A few notes: The lids don't always seal on the first try so I had a loosen and re-tighten them a few times to get a good seal. The airlock that comes with it works but as my wort cooled down it sucked in enough sanitizer that I had to refill it the next day to get a seal. I'm looking into a stopper that will fit into the lid port to allow me to use my regular airlocks but it works out of the box so I really can't complain. This is more of an FYI for other brewers used to standard airlocks. My only real complaint is that I haven't found the right tubing size to allow me to make a dip tube for filling bottles off the spigot yet. I think this is a pretty big oversight since one of the selling points for me was the ability to dispense directly from the fermenter to bottles without a siphon. Yes you can dispense into bottles without the tube but that exposes your beer to much more oxygen than if a dip tube were used. If I can't find tubing that fits I will probably buy aftermarket spigots that I can use with tubing. Overall I think these are a steal for small fermenters and they're exactly what I was looking for. I may replace the spigots so I can use a dip tube for bottling but I think most beginning brewers will be fine with what comes in the kit though it wouldn't hurt to include $0.20 of tubing to help people bottle better.

Rated 4 out of 5 by from Does what it says on the tin... I bought the Mr. Beer 1 gal fermenter because 1 gallon better fits my brewing style, plus combining it with the Mr Beer 2 Gal LBK I can do a 3 gal batch if I so choose. I recently just bottle a 1 gal recipe, and had no real issues with the fermenter. There are a few pieces of caution I would offer though before using it. 1) Before you start sticking your hand in either the fermenter (or in my case the lid) rinse it out really well. This sounds like a silly suggestion but I was placing the silicon ring in the lid to see how it would go on and i got either a glass or a plastic splinter in my finger. It wasn't horribly painful but it did sting. 2) You don't really have to put santizier in the lid, since it operates on the same principle as the MrBeer LBK. However, it is nice to have santiizer in the lid to see if it is bubbling or not. 3) You will not get all of the beer out of this fermenter, depending on where your sediment layer is it can leave a bottle and a half of beer behind. It isn't horrible to tilt the fermenter, but make sure the top lid has no sanitizer. Next time I brew with it, I might not use the spigot, but instead using a auto-siphon, and racking cane. 4) The spigot. The inside washer on mine got stained. I don't think this will matter for future brews so long as I clean and sanitize it but thought it should be mentioned. So all in all a nice little fermenter that I am happy with so far. Got a few more 1 gallon batches coming so will see how well it does with those, and if it keeps working well. Thanks Mr. Beer for the nice product. The only real complaint I have at this point is that the spigot assembly is not available to purchase by itself, and as a previous reviewer noted the current one wouldn't work well with a bottling cane.

Rated 4 out of 5 by from Nice size for experimental batches. Good for making BIAB small batches and experimental batches. Wish I could connect the bottling wand without having to use extra tubing. Tubing doesn't connect very good to spigot. I had to clamp it on so it doesn't come off.
