Good but leaky

It was good. Served it’s purpose but the parts you screw together don’t fit perfectly and require some Teflon tape to make a leak proof fot. Also the dip tube doesn’t really hold well unless you use a lot of Teflon tape. Seeing that it sits inside your fermenter, it gets quite yucky. Having to replace it every time I use it causes me to go through more Teflon tape than I would like. Other than the amount of tape, there’s nothing else I have to complain. It seemed to stay sealed and no infections got in. It’s small compact size fits nicely in most spaces and still allows room for the airlock to breathe.

Great fermenter

Awesome in every way except it needs a fourth leg. All fermenters, regardless of size, should have four legs.

Great product

Fantastic product and easy to use! Tested it out with a batch of peach and strawberry wine. Definitely need to get some of the accessories to go with it.

Upgradable

With over 25 accessories available there’s no limit to what this fermenter can do! Want to add a thermometer or sight glass? It has ports for attaching those. Want to add wheels or leg extensions to transfer directly into a keg? It can do that, too!

Stainless Steel

We all start with glass carboys or plastic buckets, but the day you graduate to stainless is the day brewing gets extra fun. 304 stainless steel is professional grade, easy to clean, scratch resistant and will last a lifetime.

Removable Lid

To remove the lid, simply pop off all five clips around the side. That way, you can get your entire arm in the fermenter to clean and sanitize it.

01 / 05

Cone Shape

Commerical fermenters are cone shaped to reduce the amount of surface area the beer and dead yeast have to interact with. A flat bottom fermenter spreads yeast out along the entire bottom. A cone shaped fermenter reduces the contact surface area by over 50%.

02 / 05

Racking Arm

Racking is when you move your beer from the fermenter to a serving vessel. The Flex has a dedicated racking port, which is the lowest port with a valve. The racking arm can be attached and rotated to the inside of the valve so you can drain the fermenter without sucking up all the dead yeast and trub that has accumulated in the cone. A racking arm comes standard with all Flex orders.

03 / 05

Tri-Clamp Ports

...two of them to be more specific. We added these connections to give you endless “Flex-ability” when you brew. Add a sample valve to pull those delicious samples or a sight glass to watch the clear beer drain out.

04 / 05

Half Batch Capable

The Flex can ferment up to 6 gallons of beer, but you don’t have to be committed to that amount every time. The Flex was designed to easily ferment a 2.5 gallon batch as well. Drink as much or as little as you want!

05 / 05

Temperature Control

We can only brew so many styles of beer at room temperature. The Flex has a specially designed temperature control system called the TC-100, which will keep your beer within 1 degree of whatever your target fermentation temperature is!
