Calculators for Draught Beer Dispense

NOW AVAILABLE  for iOS and Android phones!

McDantim’s gas blend calculators will help you find the correct blend or pressure for your draught beverage system.Conditions that are included in the calculations are:

  • Beverage temperature in the keg
  • Keg pressure required
  • CO2 content of the beverage
  • Elevation above sea level
  • Gas blend (% CO2) of existing Blender

Determine:

  • Perfect CO2/N2 blend for your specific location and conditions.
  • What range of pressures you can apply to your beverage and -maintain perfect carbonation.
  • Conversions between US and metric units.
  • CO2 content that will be maintained under unusual conditions such as high elevation systems.

The Acceptable Ranges screen will show you (highlighted in blue) the combinations of Blend and Pressure that will keep your beverage properly carbonated.  A +/- 0.2% range of CO2 volumes is the accepted industry allowance for this variation.  These results are based on values you enter into the “input” screen and will change as you modify input values.

McDantim Calculators (updated 02/17/11)

  • Easy Blend* - Use to determine the correct CO2/N2 blend.
  • Easy Volumes* - Use to determine what CO2 vol/vols your beer will become.
  • Easy Pressure* - Use to determine what PSIG to use based on your CO2/N2 blend.
  • Acceptable Range - Use to view the acceptable range for various conditions.

* Easy Blend, Easy Volumes & Easy Pressure available on mobile devices at mcdantim.mobi.

The values generated by these programs represent our best effort to be accurate.  Calculated gas blends are accurate within 1% and vol./vol. values match existing charts within 0.05 vols. or less.  Changes due to ABV are the least understood and most likely to be in error at extreme values.

These calculators are intended to be used within the range of typical temperatures, pressures, and alcohol content found in the draught beer industry today.  Extreme examples will most likely give less accurate results.

NOTE: This calculator is a Microsoft Excel spreadsheet. You will need to have Microsoft Excel or a similar program installed on your PC in order to use this calculator.
