Beer Gas Systems and Custom Blends
Serving great draft beer is about more than just the right keg and the right tap. Behind every perfect pour is a gas blend that controls carbonation, mouthfeel, and overall quality. Beer gas, a blend of carbon dioxide (CO₂) and nitrogen (N₂) is essential for delivering the right draft experience, especially for stouts, porters, nitro brews, and specialty ales.
What is Beer Gas?
Beer gas is a controlled blend of CO₂ and nitrogen used to dispense draft beer at the ideal pressure without over-carbonating or flattening the product. Different styles of beer require different gas blends to maintain flavor, texture, and pour quality.
Common Beer Gas Blends
- 25% CO₂ / 75% Nitrogen — for stouts, porters, and nitro beers
- 40% CO₂ / 60% Nitrogen — for ales, lagers, and craft brews
- Custom blends — tailored for house systems and specialty products

Beer Gas vs Straight CO₂
| Beer Gas Blends | 100% CO₂ Only |
|---|---|
| Maintains proper carbonation for each beer style | Over-carbonates stouts and nitro beers |
| Allows use of lower dispense pressures | Requires high pressures, risking foamy pours |
| Creates the signature cascade effect for nitro brews | No cascade or creamy mouthfeel possible |
| Full control over draft system setup | Limited to basic setups only |
| Better draft beer quality across diverse taps | One-size-fits-all carbonation (not ideal) |
