All About Gas


At PerfectWerks, Inc., innovation and customer curiosity are at the heart of what we do. Many of our customers are enthusiasts who love to experiment and explore the capabilities of their beverage containers. As such, we often receive questions about the use of CO2 and Nitro gas cartridges, especially regarding their interchangeability in different types of beverage containers. To clarify these inquiries, we've prepared a brief guide on the different gas cartridges and their appropriate uses.

Understanding the different types of gas

CO2 and Nitro gases are commonly used in beverage containers and have distinct characteristics. CO2 gas is typically used for creating or preserving the small bubbles in carbonated beverages like beer or club soda. On the other hand, Nitro gas generates much smaller bubbles, giving beverages like nitro cold brew a smooth, silky texture. Both gases play a role in the pressurization systems of beverage containers, aiding in the dispensing process.

It's important to note that each gas imparts its own flavor profile to the beverages. CO2 can add an acidic taste, whereas Nitro tends to have a slightly sweet flavor. This should be considered when experimenting with different gases.

Gas Cartridge Compatibility and Usage

When it comes to using these gas cartridges, compatibility and intended use are crucial. For instance, using a CO2 cartridge in a container designed specifically for Nitro beverages may result in overly foamy pours due to differing pressure requirements and dispensing mechanisms. Conversely, using a Nitro cartridge in a container originally designed for CO2 can be an interesting experiment, especially for non-carbonated drinks like certain cocktails, infusing them with a creamy texture without the need for carbonation.

For those interested in making nitro cold brew at home, it's important to consider the specific requirements of your container. While some containers are specially designed for cold brew coffee, including features like internal filters, others might require additional steps like pre-brewing and straining to prevent clogging.

Additional Considerations

When it comes to serving nitro-style beers, the choice of gas cartridge and container can significantly affect the end result. The nuances of the gases used can influence the beer's texture, carbonation level, and overall drinking experience.
