The counter pressure bottle filler that sets the standard for filling beer bottles at home.  With a unique one way valve and adjustable pressure relief you will be bottling sediment free homebrew with ease.  

If you currently carbonate and store your homebrew in kegs, you can use a counter pressure filler to bottle beer directly from your kegs. One huge advantage of this method is that since you are bottling already carbonated, clear beer, there will be no sediment at the bottom of your bottles.

Counter pressure bottle filling is how a brewery bottles beer. The bottle is under pressure while the carbonated beer flows in. Because the interior of the bottle is pressurized there is minimal loss of the CO2 in solution. The opposite of filling under pressure is when you pour a beer into a pint glass where CO2 erupts out of solution creating all that foam. Great in your glass but not good when you are trying to bottle carbonated beer. Our counter pressure filler mimics a single filling head on a professional bottling line, a concept that we all know works very, very well.

Made by Fermentap, the design has two unique features. Number 1 it is the only model made entirely from stainless steel. Number 2 you flush and fill from the bottom of the bottle.

Beer barb is 3/16". Gas barb is 5/16".

Features While some models flush the bottle from the top and fill from the bottom, our unit features a special valve that allows CO2 and beer to flow down the same stainless tube, directly to the bottom of the bottle. First CO2 flows down into the bottom of the bottle to flush from the bottom up. Next you switch the valve position and beer flows down the same tube, filling from the bottom up. The result is a more effective purging of oxygen and no foam during the filling process - not to mention that the whole thing takes one-hand to operate! Why hope that you flushed your bottle properly using a type of beer gun, when you can know for sure that you have created the best environment for your beer to be stored at by using a Counter Pressure Bottle Filler?

More Details
The unit is inserted into the bottle in the off position. The valve is then turned to CO2 to flush the bottle and then to beer for filling. The adjustable pressure relief on the side of the unit allows you control the speed of fill by adjusting the pressure in the bottle. The valve is positioned in such a way that it is easy to use with one hand, while the other holds the bottle. This model is designed for 12oz bottles but can easily be extended to accommodate larger bottles, such as 22oz, with a small piece of 1/4" tubing.

Setting Your PSI Pressure

Before you counter pressure fill a bottle make sure you are satisfied with the carbonation level and flavor. The goal for counter pressure bottle filling is to store your beer in the most sanitary and clean environment possible so when you get ready to share your homebrew its presentation is perfect when you go to pour.

An ideal set point to set your PSI level on your regulator is 10-14 psi. This range is dependent upon the temperature of your beer and the carbonation level. We recommend you start at a lower pressure around 10psi for the first 2-3 bottles to make sure you get everything dialed in before committing to filling a whole case.

Make sure your keg is always kept cold. If your keg warms up you will have foaming issues.

Ricardo m on Sep 15, 2022
The unit is designed for long neck bottles. Is it possible to use it to fill shorter bottles? The stopper is the right size, but the hole is too large to place it anywhere but the top of the tube in order to get a seal.
George Randels on Jul 28, 2019
BEST ANSWER: Hi George, unfortunately not. The stopper is not adjustable so you wouldn't be able to seal your bottle while you fill.
do I need a co2 tank for my fermzilla and for the bottle filler?
chris schatzinger on Aug 31, 2020
BEST ANSWER: You only need one tank. But you will need either the counter pressure accessory package, or a combination of the items that come with the package. My CO2 line has tee with one end that hooks up to the keg, via ball lock, and one end that connects to the counter pressure filler. This line is connected via a quick disconnect that came with the accessory package. I imagine you can treat the fermzilla as a keg and connect via ball lock or something similar.
I see that it cannot be used for shorty beer bottles. What about 22oz bomber bottles? Will I need to add a vinyl tube extension to fill bombers like you do for growlers?
Rob on Oct 2, 2019
BEST ANSWER: Hi Robert, for 22 oz bottles you will want to extend it using a piece of 1/4'' tubing.

BEST ANSWER: The Beer barb is 3/16". Gas barb is 5/16".
Does the stopper fit regular glass growlers? If not, what MoreBeer stopper will work with this to fill growlers?
DieselDad on Feb 11, 2020
BEST ANSWER: If you’re just filling a growler you really don’t need this. Now, for bottling beer in 12oz or bombers. It works perfectly. Way better than my beer gun I paid a lot more for.
what is the thread size for the barb fittings? The valve appears to be 1/4 inch npt but when I tried to add a 1/4 inch npt elbow to reorient the lines the barb only gets a couple threads into the elbow. The elbow threads into the valve perfectly. The valve is listed as 1/4 inch in the stainless ball valves section of fittings?????
Michael Rackliffe on Nov 5, 2019
BEST ANSWER: Hello Michael, the both barbs are 1/4'' MPT. As depicted in the photo, the barbs aren't threaded all the way in the valve, but Teflon tape has been added so provide a secured seal.
If I bottle a sour beer can I boil the entire unit to santize it thoughly? Will the stopper withstand high heat as well as other parts?

works really well
Like others said it took a couple of bottles to get the hang of it. And the bleed valve on the side needs to be unscrewed a surprising number of turns- feels almost like it's going to fall off in your hand, but it doesn't. It worked great.

Just what I needed
I bottle a lot of beers and sparkling wine, this counter pressure filler makes it easy to fill the bottles and keep the carbonation in the beverage, took a little getting used to but after that it is a breeze to use.

It works Great
This device does exactly what it says it does, I consistently get fills within 3/4" of the top of the bottle. It works on standard long neck bottles but not as well on the shorter bottles

Works great
Very easy to use. I mounted it on a wall bracket right next to my bench top capping machine and it has really simplified the bottling process. It is also a much cleaner process with less wasted beer compared to the spring loaded bottle fillers.

Thousands bottled.
Been bottling Ten Towers Cider with my 4 head counter pressure filler for two years and now I need to replace one filler due to leaks. Not bad after thousands of bottles through it.

Finally A CP Filler That Works!
PROS: The exhaust gas regulator is a great feature that makes this filler used-friendly.
Simple construction means easy cleaning.
I found that a half-filled growler makes a good resting holster while capping.
CONS: Neither hose-barb fitting was common to my system hose size. Had to buy $13 worth of new sizes.

The Way to Go
Well made unit, works very well to fill with minimal bubbling. Set it up with a tubing rig with a quick disconnect on the air line and its super convenient.
