nice piece of equipment...
my son is going to start the first batch for Christmas... the piece of equipment is amazing offers every feature you could think of...

Love the new equipment
While I have not yet used the equipment I am looking foward to it as my small scale winemaking equipment,it is well made and the components will cross over quite nicely!!

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.

Nicest fermenter I’ve owned
Very nice fermenter. Awesome craftsmanship.

Spike 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

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, too!

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.
