Liquid Nitrogen Dosing - Beer
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.
