Beer Gas

Carbon dioxide (CO₂) is by far the most widely used gas in the beer industry, naturally produced during fermentation and often added during packaging to maintain proper carbonation levels. Nitrogen (N₂) has gained popularity, especially for stouts and certain ales, as it creates a smoother, creamier texture with its smaller bubbles and denser foam.

Mixed beer gas blends nitrogen and carbon dioxide in specific ratios (typically 70/30 or 75/25) to achieve optimal dispensing pressure without over-carbonating the beer. This specialized mixture, commonly called “beer gas” or “mixed gas,” ensures consistent pours with perfect foam heads, particularly beneficial for draft systems with longer lines and for beers that require specific texture and mouthfeel characteristics.
