In stock, will ship on Saturday, April 1

Our Siphonless Fermentor completely eliminates the need for messy siphoning with its unique invert tube valve, which keeps silty sediment out of the valve during fermentation, and acts like a siphon hose ideally placed just above the yeast sediment when draining. Made entirely of food grade plastics (no BPA), our Siphonless is a rugged and easy to clean fermenter. All parts are easily disassembled for easy cleaning. 

 6 gallon (total volume) fermenter holds 5 gallons of beer, with room for foaming. Gallon markers on the side of the translucent Siphonless make it easy to  measure half batches, or water to fill a brewing pot. The lid features a hollow rubber gasket for an air tight seal. The valve fits the 4’ of 3/8” tubing included for oxidation-free transfer of the raw beer into our Priming Tank.

Includes invert tube valve, lid,  airlock, 4’ of tubing, and illustrated instructions. 21” high (including airlock height), 13” deep. Withstands temperatures of up to 170° F.

Leaks air

Review by sakisipper on 10/23/2021

I like it but it isn't air tight and the grommet for the air lock isn't snug enough on the air lock.

Siphonless Fermenter

Review by Nick on 10/23/2021

I have used these for 10+ years. Pros:They are great for leaving the trub behind, and double as priming vessels. Much easier to use than a siphon pump. Cons: The inside of the valve stains permanently, the gasket in the lid falls out easily and they are a bit pricey but a lot less than a conical fermenter and don't require a stand. William's Responds: Thanks for the review. The latest model features a lid gasket that does not fall out.

Easy to use and a classic. I have used it with or with the rubber gasket and have never had a bad batch. If by chance you do have a very vigorous primary ferment it's much safer than a glass carboy with an airlock. Highly recommended!

My easy goto fermenter

Review by Avery on 10/22/2021

Love the Williams siphonless fermenter! Have made more than 20 batches of beer and I love how easy it is to use. No racking or siphon just easy transfer by opening the valve. I put a mesh filter bag on the end of the transfer tube in the bottom of my keg. Quick transfer and very easy cleanup. I do not transfer to a secondary. Two weeks in the fermenter then add dry hops for one more week. Transfer to keg after three weeks in the siphonless and my beers come out great!

Best out there

This fermentation bucket rivals Speidel in quality and practicality. Lid has nice "wave" on the outer edge for easy prying off. Seals great. Spigot has been perfect height for all my batches so far (but it also has a racking arm!). For the price and making the transfer process so simple, I might move to this for all my buckets.

Q: can one remove the top lid o-ring for cleaning?

A: It would be very difficult, and we think you would damage the rubber O ring if you tried to remove it.

Q: How do I seal the lid of the fermentor? Just push down hard?

A: Yes, after you remove the tear strip with a pair of pliers.

Q: Can you just purchase the o-ring for the outlet spicket?

A: We do not sell this separately, although we sell a replacement valve that includes this part (item E39).

Q: I need a blow off tube for this. Been using some very active yeast and it just clogs up the air locks. Tried three different pieces of tube I had on hand and none came close to fitting snug in place of the air lock. What size tube can we use?

A: If you have our more modern Siphonless lid with a 5/8" hole, our item J58 thick wall thermoplastic tubing works although you cannot see though it. It is a bit of a squeeze, but you can also get our J58 1/2" Silicone Tubing to work
