How to Choose the Best Gas Cylinder for Your Kegerator - A Comprehensive Guide

For beer enthusiasts who own kegerators, having a reliable gas cylinder is crucial for proper cooling, storing, and dispensing of draft beer. The two main types of gas used for kegerators are carbon dioxide (CO2) and nitrogen (N2). In this comprehensive guide, we will explore the factors to consider when choosing the best gas cylinder for your kegerator.

Gas Choice:

  1. CO2 - Most beer types are carbonated using CO2. CO2 gas is highly effective in maintaining a stable pressure for long periods, keeping beer carbonated and fresh.
  2. N2 - N2 gas is commonly used for dispensing stouts like Guinness. It adds a smooth, creamy texture to the beer, which is highly desirable for these types of beers.
  3. Blended gas - This type of gas is a mixture of CO2 and N2 and is used for specific beer styles.

Tank Size:

Gas cylinders for kegerators come in different sizes. Here are the most common sizes:

  1. Small - 2.5-5 lbs
  2. Medium - 10-20 lbs
  3. Large - over 20 lbs

The size you choose depends on how much beer you plan to dispense and how often you plan to do it. Homebrewers typically prefer a 5-pound cylinder because it's easy to carry around and transport if needed.

Material Choice:

  1. Aluminum - This material is lightweight and corrosion-resistant. It is the most common material used for gas cylinders for kegerators.
  2. Steel - Steel is durable and has a longer lifespan compared to aluminum. However, it's heavier and more prone to corrosion.
  3. Composite - This type of material is lightweight and has excellent durability. However, it's relatively expensive compared to aluminum and steel.


When handling gas cylinders, safety should always be a top priority. Here are some safety tips to keep in mind:

  1. Make sure the tank is always securely mounted and kept straight in the vertical position.
  2. Monitor the tank pressure and do not exceed the recommended levels.
  3. Store the gas cylinder in a well-ventilated area away from heat sources. - Your One-Stop Shop for Gas Cylinders: When looking for high-quality gas cylinders for your kegerator, is your one-stop shop.
