What is mixed gas, exactly? In draft beer service, mixed gas is a controlled blend of carbon dioxide and nitrogen used to push beer from the keg to the tap while preserving carbonation, flavor, and pour quality.
The right blend reduces foam, limits waste, and keeps beers tasting just as intended. Broward Nelson provides mixed gas, delivery, and draft system support for bars, restaurants, breweries, and venues all across South Florida.
What Is Mixed Gas Made Of?
Most beer mixed gas is made from CO2 and nitrogen. CO2 supports carbonation, which gives beer its crisp mouthfeel and preserves the brewer’s intended flavor profile. Nitrogen adds pressure and stability, as it doesn’t dissolve into beer as quickly as CO2 does.
One of the most common blends is 75% nitrogen and 25% CO2. Broward Nelson also supplies blends such as 60% CO2 and 40% nitrogen. However, too much CO2 can over-carbonate beer and create foam; nitrogen pushes beer over longer distances without adding the same level of carbonation.
Why Mixed Gas Is Used in Draft Beer Systems
Mixed gas is usually used when a draft system needs more pressure than CO2 can provide on its own. Long-draw systems are the clearest example; in such setups, beer travels from a walk-in cooler to a bar, taproom wall, or stadium concession area through long lines.
At higher pressure, CO2 alone can over-carbonate beer before it gets to the tap. But with the right nitrogen and CO2 blend, the system moves beer while keeping carbonation in the right range. Without the right gas blend, you stand to lose product, profit, and consistency.
Benefits of Using Mixed Gas
Mixed gas gives operators greater control over the pour, especially during peak service hours. A properly balanced system can deliver consistent pour quality, reduced foam and waste, better-tasting beer, more efficient keg usage, and stable pressure over long distances.
For bars, breweries, restaurants, and venues, that translates to fewer dumped pours, less staff frustration, and more pints served promptly.
Mixed Gas vs. CO2: What’s the Difference?
CO2 is typically best for short-draw systems where the keg sits close to the tap. It directly carbonates the beer, uses a simple setup, and works well when pressure needs are modest. Broward Nelson also supplies CO2 cylinders for these applications.
Mixed gas is often better for long-draw systems, nitro beers, and setups that require higher serving pressure. Nitrogen provides the push, while CO2 maintains carbonation. The right choice ultimately comes down to the line length, beer style, temperature, pressure, serving volume, and equipment.
Industries That Use Mixed Gas
Bars count on mixed gas to control pour quality during high-volume service. When taps are busy, a balanced system helps bartenders pour faster without fighting against foam. Breweries trust mixed gas in taprooms, tasting rooms, and draft distribution setups, where different beer styles can call for different carbonation levels.
Restaurants use mixed gas for long-draw beverage systems where the keg room is far from the bar. Stadiums and large venues use mixed gas since distance, volume, and speed all contribute to pressure demands. Extended lines demand stable gas pressure, with every lost pour multiplying across hundreds or thousands of orders.
Mixed Gas System Installation & Supply
Mixed gas performance is dependent on more than the cylinder. Tank size, regulator settings, line length, temperature, keg storage, gas storage, and service schedule can all affect results. That’s why experienced beverage gas technicians match the system to the real operating environment.
Broward Nelson supplies beer gas tanks in multiple sizes, sets up and calibrates draft systems, balances pressure, and provides ongoing refills and monitoring. For higher-volume operations, we also support on-premises blended gas with cutting edge gas blenders that combine CO2 and nitrogen on the spot.

| Factor | On-Site Generation | Nitrogen Tanks |
| Cost | Higher upfront cost, but long-term savings for heavy users | Lower upfront cost, ongoing delivery, and rental costs |
| Convenience | Produces gas on demand when properly maintained | Requires tank swaps and delivery planning |
| Reliability | Strong fit for steady, high-volume use | Practical for lower-volume or seasonal use |
| Maintenance | Calls for filter changes, compressor care, and service checks | Needs cylinder storage, regulator checks, and safe handling |
| Space | Reduces spare cylinder storage, but needs equipment space | Requires room for active and backup tanks |
| Safety | Less cylinder handling, but still requires ventilation | Demands secure storage and trained handling |
Common generator problems usually arise from poor sizing, dirty filters, moisture in the air supply, incorrect pressure settings, or skipped maintenance. Top red flags include low purity readings, pressure swings, unusual compressor noise, or inconsistent pours.
Why Choose Broward Nelson for Nitrogen Systems
Broward Nelson has proudly served South Florida beverage businesses since 1965. We work with bars, restaurants, breweries, coffee shops, stadiums, and hospitality groups that need gas systems to perform day in and day out.
We’re here to help with system design, installation, maintenance, and support. Our team sizes equipment, reviews draft line needs, sets up gas blending, and plans backup supply. If you’re comparing a cylinder to a nitrogen generator, experienced guidance can help prevent an expensive mismatch.
We also understand how nitrogen fits into the full beverage program. A draft system might need nitrogen, CO2, mixed gas, regulators, blenders, and backup cylinders all working together. Meanwhile, a coffee shop might only need a simple setup for nitro cold brew, but it still needs to have consistent pressure and safe storage.
Broward Nelson provides fast service throughout South Florida, plus emergency support when gas supply impacts daily operations. For businesses where cylinders are still the better fit, we also supply nitrogen gas.
Get a Nitrogen Generator for Your Business
A nitrogen generator can be a wise investment for businesses that use nitrogen on a daily basis and want fewer delivery headaches and stronger control over beverage quality. To determine the right system, carefully consider volume, available space, purity needs, pressure requirements, backup planning, and service access.
For breweries, restaurants, bars, and coffee shops, the decision boils down to practicality: are cylinders still enough, or has demand reached the point where on-site generation can save time and reduce risk?
Broward Nelson can evaluate your current setup, estimate gas demand, and recommend the best path forward. Request a quote for solutions tailored to your business.
