Liquid Nitrogen Dosing - Beer

CHALLENGE

  • Inert for oxygen reduction
  • Nitrogenate: with or without a widget

SOLUTION

Dissolved oxygen in beer is closely monitored and controlled throughout the brewing process, but O2 pickup can occur during filling. Reducing O2 in the headspace preserves the flavor and aroma of the beer.

Nitro-style beers are a growing segment of the craft brewing industry. The same equipment used to purge the headspace can also be used to nitrogenate a beer to get the smooth, creamy, and attractive cascade effect after pouring, with or without a widget.

HOW LIQUID NITROGEN DO SING WORKS

  • A small, precise droplet of Liquid Nitrogen is dispensed into a can or bottle
  • The LN2 vaporizes, expanding to fill the headspace
  • Sealing the container before the vapor escapes traps Nitrogen gas
  • The trapped volume of gas pressurizes the can or bottle, forcing Nitrogen into solution
  • To inert the headspace, the vapor must be allowed to expand and push out O2 before the container is sealed.

ADVANTAGES OF USING LIQUID NITROGEN

  • Nitrogen is inert — will not react with product
  • Efficient & Versatile — can be used in many different packaging applications
  • 78% of atmosphere is Nitrogen — readily available and safe
