Beer Taps: Carbon Dioxide is Your Hero

When you go to a restaurant or bar and order a beer on draft, you may not understand how your ice-cold beer is dispensed from the tap.  Let’s review the basics of the draft system and how carbon dioxide is the unsung hero.

Beer taps work through constant pressure in the system. When the tap is pulled to dispense beer, carbon dioxide flows into the pressurized beer keg, mixes and pushes the beer upward through the beer line and tap into your glass. The carbon dioxide compressed gas acts as the carbonation for the beer when it’s dispensed and allows the beer to taste its best.

Having the correct carbon dioxide pressure in the beer dispensing system is important as it keeps the beer from being over-carbonated (too foamy) or under carbonated (flat). Patrons and staff can quickly tell when the pressure is off by looking at and tasting their beer. Pressure regulators on the beer dispensing system help owners identify these kinds of issues and adjust the flow accordingly. Common pressures for ales and lagers in the US are between 10 to 12 PSI (Pounds per Square Inch).

 

Nitro Beers

For nitro beverages like coffee or beer, the compressed cylinder used in the dispensing system is a mix of both food-grade carbon dioxide and nitrogen. Often times the ratio of gases is 70% nitrogen and 30% carbon dioxide for nitro beers. The exact ratio of the two gases will depend on the type of beverage being served. Nitro beers are kept under higher pressure between 25 and 30 PSI compared to ales and lagers in the US.

 

Party Kegs and Carbon Dioxide Cylinders

The benefits of using a kegerator with carbon dioxide over a hand-pumped keg:

  1. Beer can be stored longer in kegs using carbon dioxide than an oxygen pump system. An oxygen pumped keg will cause the beer to spoil quickly due to oxidation within 24 hours of being tapped.
  2. Dispensing beer at a constant correct pressure. Hand-pumped kegs can be under or over-pumped resulting in foamy or flat beer.
  3. With a carbon dioxide system, you avoid the oxygen pumped keg issue where the first few glasses of beer dispensed are too foamy and unusable. The carbon dioxide system helps you avoid foamy beer from the start thanks to the pressure regulator indicator.

 

Easy Steps for Getting Your Keg Cylinder Refilled

Air Source Industries can fill your carbon dioxide cylinders for your kegs before your next party. If you don’t already own a carbon dioxide cylinder and are planning to use one long-term for your social gatherings, we are happy to rent or sell you a cylinder. Our Long Beach facility is conveniently located at 3976 Cherry Ave just north of the Long Beach Airport and a few minutes from the 405 freeway. We’re open weekdays between 8 AM and 5 PM for in-person service.

First, bring in your carbon dioxide cylinder to our facility and let our front desk service team know you are looking for a food grade carbon dioxide refill. You’ll drop your cylinder off and our gas applications team will fill it. If you’d like same day drop off and pickup, we recommend dropping off your carbon dioxide cylinder in the morning so our team can have it ready for pickup in the afternoon.
