40 Gallon Conical Fermenter


The Minibrew® Barrel Maker - 40 Gallon Conical Fermenter

Known as The Barrel Maker, our 40 gallon Conical Fermenter will get you started if your ready to start one barrel batches. This is all you need to make the leap to that next level.  When you have that perfect recipe or when you are just starting in your Craft Brewery, experience professional results at a fraction of the cost with The Barrel Maker.

Our larger tanks ship in multiple boxes or on pallets, depending on which Fermenter and or which stand option you may desire.  Therefore the rates are easiest to calculate when the shipping information is entered directly into the carrier sites, or contact is made with a freight forwarder who can provide multiple options based on how quickly something is needed.  Therefore, we ask that you contact us regarding shipping and we'll be happy to help!

Without a stand, this size fermenter is capable of being stacked and several on top of each other. If you don't need a stand or can build one, need more than one fermenter, shipping would be substantially cheaper as the tanks can be stacked on the same pallet.  

Brewing Great Beer is Up to You


Remove trub and dead yeast from the large bottom valve. Now you can skip the bright beer tank or the secondary fermentation vessel. Save the 30% of the yeast that is live for the next batch. Forget about siphoning as this is too risky when you are brewing a full barrel of beer, or anything else.  

The new & improved easy-off larger lid makes cleaning it a simple process.  And, the new Lid within a Lid allows you to make additions and dry hop without taking the larger lid off.  You can simply use the 4" Threaded Lid which is located in the center of the Larger, take-off Lid.  

To generate more sealing pressure on the larger lid, simply attach a set of rubber straps or ratchet straps from one side of the Top Hoop, up and over the Lid, and back down to the other side of the Top Hoop.

Load from the kettle through the bottom valve or through a port on the lid. Use the racking port for transferring to a keg, specific gravity testing and the opportunity to taste your beer in progress.

Eliminate potential contamination opportunities by completing your fermentation in one vessel.

Experience professional results batch after batch.  

Thermometer is Included.
