BrewDemon Conical Fermenter Features

Easy Brewing

With BrewDemon conical fermenter, you can complete your brewing process in 3 easy steps.

The first step is to sanitize the equipment. Do not use an acid based sanitizer like Star-San as it can deterioriate the spigot in the long run. Use an oxygen based like One Step or an iodine sanitizer instead. This 15-minute process will kill any bacteria, mold, or wild yeast that can affect the taste of your brew.

The second step is fermentation. At this stage, you need to add the mix, yeast, and water. BrewDemon mixes (not included and sold separately) are ready for fermentation and contain malted extracts and hops.

After 7 days of rest, the third step is to carbonate your beer and bottle them. Use a bottle capper to make sure they are sealed properly and its suggested to wait 2 more weeks until you should drink your brew.

Large Opening

The large opening of the BrewDemon conical fermenter allows easy access for adding water and other ingredients. You can put your hand in the conical unit and reach every surface to clean it thoroughly. 

Efficient Vent System

The unique venting system of the BrewDemon fermenter allows CO2 to escape while keeping out any harmful contaminants. Instead of notches, the BrewDemon has a vent hole that comes with a vent plug helping the gas to escape and not become clogged in the process. This can be upgraded with an airlock that is included in the product package or you can add a blow-off tube. 

Superior Build Quality

The material of the BrewDemon conical fermenter is BPA-free professional-grade, durable food-grade PVC. This high-quality material does not impart any unwanted flavor to your brew. 

The whole package of this fermenter includes the translucent conical container, fermenter base, tap/spigot, stick-on temperature gauge, CO2 vent plug, and upgrading tools like an airlock, lid gasket, and rubber stopper.

Intelligent Design

The conical design of the BrewDemon fermenter is not for merely aesthetic purposes. It is built keeping in mind what professional brewers use. Due to its conical shape, it helps to reduce the amount of surface exposure to the wort. 

Less surface exposure reduces the chances of affecting the flavors of the beer. The conical design also ensures that all other solid residues including the trub, yeast, and hop matter settle down beneath the valve. 

Clear Measurement

For your convenience, measurements are molded on the back of the outer surface of the fermenter. In terms of clarity, the BrewDemon measurement markings are much more sophisticated than other brands. 

Starting at 1-gallon it can measure up to 2.5-gallons. You can also find a stick-on thermometer with this fermenter. It helps you to note the temperature for pouring various ingredients like wort or yeast. 

Adjustable Flow Spigot

The flow spigot is made from plastic but it is well-made. This device is sturdy and made to last. With this high-grade tap, you would not have to worry about any breakage. 

The spigot also has an easy on/off lever function. It helps to adjust the flow and make it easier to bottle. The barbed spout secures the attachment of any hose or bottle filler to the spigot. 

Recipe Kits

Thanks to pre-made recipe kits that you can buy from BrewDemon, it removes several steps from homebrewing that make it easier for beginners. It also allows for more room for brewing beer instead of pellet hops taking up more space.
