Flex Buyer's Guide

New to brewing? Haven't bought a Spike fermenter but feeling overwhelmed with the options? Well, we put together a Buyer's Guide just for you!

Racking Arm Included

The Spike Flex includes a rotatable racking arm as a standard item. This allows you to rotate the racking arm as you drain your Flex. You’ll start draining in the upwards position and rotate until the beer stops running clear. And since the Flex was designed to be modular, the full tri-clamp racking arm with a position indicator can be purchased at a later date as a cool new upgrade!

4" Lid Port

The Spike Flex features a 4” tri-clamp welded onto the lid. Why? Modularity. This allows you to attach our drop in temp control coil, clear cap and allows for easy hop additions. Our temp control coil extends deep into the Flex so both full batches (5-6gal) and half batches (2.5-3gal) can be efficiently cooled. The 4” port also allows for unmatched simplicity when adding hops during your fermentation. Gone are the days of removing the entire lid which allows oxygen in and also opens the door for an infection.

TC100 Full Temp Control Package

Temp control is arguably the most important aspect of brewing. Proper temperature control can eliminate off flavors and manipulate flavor profiles that different yeasts produce at different temps. Up until this point precise fermentation temp control was only available on larger more expensive fermenters – not anymore. Our full temp control package includes the temp coil, insulated tubing, quick connect tube fittings, cooling pump, insulated jacket and dual temp controller. We also have a heater available for us cold weather brewers. All that’s needed for cooling is a cold water source! Many people use a cooler with ice, fridge with a glycol reservoir or even a glycol chiller!

Great product

Fantastic product and easy to use! Tested it out with a batch of peach and strawberry wine. Definitely need to get some of the accessories to go with it.

Spike Flex fermenters are awesome

I have a blonde ale that I just bottled up from this vessel and it has been perfect for a home brewer. The ease of use and upgrade options are exactly what I was looking for.

Just bottled my first batch

This is my first "real" fermenter after using buckets previously, so I was excited to receive my order. Unfortunately it was missing some gaskets for the tri clamps, customer service were excellent and sent them out after I asked, but it put my brew day back a week. I had seen one reviewer talking about plumbers tape for the valve, this is a MUST! I transferred into my fermenter only to have a steady drip from the connection, had to play pass the parcel between vessels while I added some. It would be nice if there was a note about needing this, or some instructions at all. The rest is all good, excellent build quality, nice and sturdy, fully expect to be using this forever.
