CF 5 Review

I purchased the CF5 with most all options. It is a fantastic piece of equipment and fun to use and will greatly improve and simplify my home brewing process. Customer support was awesome. Only complaint is hard copy instructions could be better. Seem written for those somewhat familiar with conicals versus someone brand new like me.

Cf10 is great

Cf10 is just as good as my Cf10. However they pressure relief valve is supposed to be 15 PSi but it is more like 9.5

Love this Conical

Total game changer. Love all the added things I can do with it. Bought the CF10. Upgraded from buckets and carboys. The quality of craftsmanship on this is just amazing. Beautiful piece of equipment. Highly recommend.

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.

Works great. Glad I upgraded.


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.


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.

Endless Accessories

With over 25 accessories available, there’s no limit to what your Conical Fermenter can do! All accessories come “a la carte” so you can outfit your Conical exactly how you want. It doesn’t make sense for us to guess how you’ll be brewing and charge for accessories you don’t need. Want to pressure transfer to a beer keg? We can help with that! Want to add wheels to move your Conical? Sounds good. Want to… you get the point.

Tri-Clamp Fittings

The CF line uses tri-clamp fittings. A tri-clamp fitting uses a gasket and clamp to make a sanitary connection. It is the only connection you’ll find at a professional brewery. They're easy to use, never leak and are considered a standard connection, so almost any accessory can be attached.

03 / 06

Removeable Lid

The entire lid is easily removable so you can keep the inside (and outside!) squeaky clean.

04 / 06

Half Batch Capable

The racking port, sample port and thermometer port are all low enough to be able to do a full volume batch as well as a half batch. All accessories like the temperature control coil, heating pad, etc., are designed to work with a half batch as well.

05 / 06

Oversized Bottom Port

Our CF’s have an oversized (but arguably necessary) 2” tri-clamp bottom dump port. Due to the pressure being exerted, the odds that this port gets clogged are slim to none.

06 / 06

CIP Capable

Add our optional CIP ball to the 1.5” tri-clamp port on your lid and connect that to a brew pump. The pump will spin the ball and power wash your CF, making hand scrubbing a thing of the past!
