Counter Pressure Bottle Filler - Stainless Steel with PRV

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. 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.

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, this 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!

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 valve 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 depends on the temperature of your beer and the carbonation level. 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.
