A complete guide to nitrogen for breweries
Brewers can use nitrogen (N2) for different purposes throughout the beer making process
N2 versus CO2
Traditionally, brewers have relied heavily on CO2 as an inert gas that is also a natural byproduct of the fermentation process. However, nitrogen has important advantages over CO2, starting with significant cost savings.
Oxygen is the enemy
Oxygen is beer’s worst enemy. It can react with multiple compounds found in beer, leading to oxidation. This in turn can severely affect the flavor, aroma, color, and shelf life of beer. Nitrogen is an inert gas and does not react with beer compounds, making it ideal for many beer making processes. By displacing oxygen, nitrogen helps preserve the beer's intended flavor and quality.
Nitro beer
Injected with nitrogen instead of only carbonated by CO2, nitro beers have a smooth, creamy texture. Adding to their appeal, they also have rich aromas, a longer-lasting foam head, and a cascading pour.
In this article, we will go into how, when and where brewers use nitrogen and explain the benefits of nitrogen for breweries. Finally, you will read why nitrogen generators are the most reliable, cost-efficient N2 solution for breweries of all sizes.
Nitrogen in the beer brewing process
Breweries rely on nitrogen extensively, especially in applications with direct contact with the product:
