  #10 Size Stopper With Hole (+ $2.25)
  3 Piece Airlock (+ $1.50)


Unbreakable crystal clear PET plastic fermenter features thick PET walls that do not require ribs or texturing for strength. Easier to clean than ribbed fermenters, and easier to see through. BPA-free plastic, molded  in Canada. 11" wide, 22" tall (not including airlock and stopper). Includes a ½" hose barb outlet valve that accepts ½" interior diameter tubing.

This 7 gallon Fermonster features a 4" diameter O ring sealed lid for easy cleaning, that takes a #10 stopper and airlock (stopper and airlock not included, you will be given the opportunity to purchase these when you put this in your cart). Gallon markers are molded into the side at 5, 6, and 7 gallon steps. An optional solid lid is also available in case you want to use your Fermonster for storage, or want to drill your own  airlock holes.

Tight fit
Lid opening is still small. Had to get daughter to clean inside. Can’t get my arm inside. O ring was over sized and won’t sit in groove. Big mouth bubbler is a better product. This needs a larger opening and then it will be 5 stars

Lives up to its hype
I brewed cider and just bottled using this product.  It worked well for me, and the ease of cleaning compared to the one with smaller opening makes a huge difference. I used a wash rag in the small one, tumbling it about until the residue was gone.

But with this large opening, that is no issue.

Does the valve gasket go on inside or outside? The gasket is slightly tapered so should narrow end face hole in Fermonster or does it matter? Also noticed that The Vintage Shop website says the valve comes with two O-rings. Mine came with just one gasket.
We have had good success mounting with the gasket on the outside (no interior gasket).

Do you sell carrying straps?
Yes, look at our item J67, the Brewhauler.
