This Deluxe Counter Pressure Bottle Filler is made entirely of stainless steel (except for a brass backing on the pressure gauge), and has an easy to use Stainless 3-way ball valve on top and adjustable stainless pressure release on side. With this filler you flush and fill from the bottom of the bottle not from the top. Breweries use counter pressure systems for bottling their beer to preserve the foam in the beer and eliminate messes. Because the counter pressure filler pressurizes the inside of the bottle, there is minimal loss of the CO2 in solution, thereby preserving the foam. Our counter pressure filler mimics a single filling head on a professional bottling line, a concept that we all know works well. Beer barb is 1/4". Gas barb is 5/16".
If you currently carbonate and store your homebrew in kegs, you can use a counter pressure filler to bottle beer directly from your kegs. The advantage of this method is that by bottling already carbonated, clear beer, there will be no sediment at the bottom of your bottles.
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. You insert the filler into the bottle in the off position. Then you turn the valve to CO2 to flush the bottle from the bottom up. (The adjustable pressure relief on the side of the unit allows you control the rate of fill by adjusting the pressure in the bottle. The valve is easy to use with one hand, while the other hand holds the bottle.) 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.
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. 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 10 psi 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.
