Incredibly well built

I haven't used it yet so I can't comment on actual usage. I researched it while my last batch was in progress and wanting to improve my process. I'm super excited to use it with my next batch. Just looking over it and checking the connections, it seems incredibly well built. The add-ons are fantastic, although I wish some came standard because they are pricey, but then again you are getting top quality gear. Do your research, but I think you'll find spike conical are the way to go.

Everything is great except the lid

This fermenter would be perfect if they just went with a tri clover fitting on the lid. Getting the gasket correct and the clamp tightened properly is a huge pain. I should have to spend hours troubleshooting a lid to get it to sit properly. I love every other product I have got from spike but this is not one of them.

Overall this gets the job done!

Minor inconvenience with the v1 seal. I fermented a west coast ipa under pressure and was barely getting 10 psi. I depressurized and tightened the HELLout of the band clamp and seemed to fix it. PRV was on and held to 15psi. I contacted spike about the pressure issue and they sent me the new version of the gasket - best customer service! Super anticipating a jacketed model!

Undersized cooling coil

I don’t like that I cannot call and speak to someone when I have an issue. Cooling coil for this fermenter is under sized. I have a half barrel fermenter from SS BrewTech that has a larger could. I can cold crash the SS BrewTech fermenter into the 30s but yours I can only get down to the low 40s. Have a professional grade glycol chiller running.

10 gallon conical

Purchasing was easy! I have the 5 gallon and needed a second conical to make more of my beer and for split batches. I like the extra size stabilizing plate, I think it adds to the stability than the smaller one.


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!
