Thoughtful Engineering
Many home brew products modify existing hardware for brewing. Take a spaghetti pot, drill a couple of holes, and add some accessories that don't exactly fit. Everything about Spike Brewing products fits. Every design detail has been thought through and the question of "what is best" is obviously sought-after. I plan on changing out my older equipment and continuing to invest in Spike.
United StatesNicest fermenter I’ve owned
Very nice fermenter. Awesome craftsmanship.
United StatesSpike Flex Plus Fermenter
Made my first brew using it and it AMAZING. Love the way that I don’t have to use hoses to pour from fermenter to bottles and now I have a way to pressurize my fermenter if I want to do a keg which I did not have that option on my plastic fermenter and it is very easy to clean
United StatesFirst Ferment Performed Great
What a GIANT step up from plastic buckets! Right out of the box, this beauty was easy to set up and put to work! I purchased the legs/shelf/casters and may not use them in the future for cleaning purposes. (I will have to completely disassemble to take upstairs to the kitchen sink to clean) However, fermentation was amazing! Performed excellent and easy to sample through the process. Temp control was spot on! (Used heater only as my basement is cool) You won't regret putting your buckets into retirement and upgrading to this!
United StatesGood but leaky
It was good. Served it’s purpose but the parts you screw together don’t fit perfectly and require some Teflon tape to make a leak proof fot. Also the dip tube doesn’t really hold well unless you use a lot of Teflon tape. Seeing that it sits inside your fermenter, it gets quite yucky. Having to replace it every time I use it causes me to go through more Teflon tape than I would like. Other than the amount of tape, there’s nothing else I have to complain. It seemed to stay sealed and no infections got in. It’s small compact size fits nicely in most spaces and still allows room for the airlock to breathe.
Pressure Capable
The main selling point of the Flex+ over the standard Flex is the ability to pressurize up to 15psi compared to the Flex’s 2psi capabilities. What does this mean? Pressure capable means you can carbonate beer inside your fermenter (as opposed to bottles or kegs) in a little over 24 hours as opposed to a week. You can also pressure transfer your beer directly into a keg or bottles, eliminating any oxygen exposure.
Upgradable
With over 25 accessories available there’s no limit to what this fermenter can do! Want to add a thermometer or sight glass? It has ports for attaching those. Want to add wheels or leg extensions to transfer directly into a keg? It can do that.
Stainless Steel
We all start with glass carboys or plastic buckets, but the day you graduate to stainless is the day brewing gets extra fun. 304 stainless steel is professional grade, easy to clean, scratch resistant and will last a lifetime.
Removable Lid
To remove the lid, simply pop off all five clips around the side. That way, you can get your entire arm in the fermenter to clean and sanitize it.
