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.
