Excellent Equipment
This equipment brings not only the feeling of a mini brewery, but it gives you the confidence to keep experimenting and creating great beer. In the future I would have loved to get the add option for the blow off tube and sight glass on the purchase menu.

CF5
Works great. Glad I upgraded.

Life is good!
I actually have two of these bad boys (need two more but…$) and every time I use them things get easier and more user friendly. They should include the pressure bundle for the price but whatever. There are a few pieces and parts you will need to get the most out of these conicals, like a 2” QC fitting, 1 1/2” QC fitting, and definitely get the wheels. They raise the unit up to a usable height and make clean up and storage a breeze. So far so good!

ITS A BEAUTY
Easy to get everything together. Looks amazing. I love the giant lid, easy to clean. I spray it out with a hose, in place, and dump out the bottom. Trub dumps, yeast harvest and doing multiple brews on top of the same yeast is really easy. Love having a sampling port. Can ferment under pressure, use some pressure to blow out thick trub, pressure transfers, and carbonate in the tank. Downside is accessories added up. Would love to see some options to choose from with the conical and some accessory packages to get a better deal. I needed a gas block, temp coil, thermowell and two racking tubes (prevent pickup of yeast in your sample or transfer that settles on the ports) . Brewing is going great, have even pushed capacity much lower than recommended without much issue. Have Just added leg extension, new (big) casters which are perfect and a neoprene coat to keep the cold in and prevent sweating-havent used it yet. Fermenting is getting more fun.


Beats anything anyone else has hands down!
This fermenter replaced my SS Brewtech 7 gallon. The use of all TC is SO much easier to clean and use! I really enjoy using this fermenter! The craftsmanship is top notch and the price is fair. I have since bought other accessories and will continue to do so!

3-Port Lid
Every Conical Fermenter comes with a standard lid with three 1.5” tri-clamp ports. The ports are specifically designed for a blow off port, hop addition port and a pressure relief valve (PRV) port so you can stay safe when your CF is under pressure.

Locally Welded
We weld all our CF fittings right here at our facility in Milwaukee, WI. Why does this matter? It means we have control over our strict quality standards. Most competitor models are welded overseas, so there’s fewer quality and control checks throughout the process. Spoiler alert: Sanitary welds are very important when you’re making something that will eventually be consumed.

Unitank
A Unitank refers to a fermenter that can ferment and carbonate beer in one vessel. Cut down your carbonation time from 7 days in bottles and kegs to just over 24 hours using a CF Unitank and our carb stone!

Temperature Control
Temperature control is crucial to fermentation. Some beer styles can be kept at room temperature, while others need to be kept cooler. The Spike CF line has a temperature control system (the TC-100) which will keep your beer within 1 degree of your fermentation target temperature.
