Nitrogen cold brew has taken the coffee world by storm, and for good reason. This innovative brewing method combines the smooth, low-acidity flavor of cold brew with the velvety texture and Guinness-like cascading effect of nitrogen infusion. In this article, we’ll delve into the world of nitrogen cold brew, exploring its history, benefits, and most importantly, providing a step-by-step guide on how to make it at home or in your coffee shop.
What is Nitrogen Cold Brew?
Nitrogen cold brew is a type of coffee that’s brewed without heat, using cold water to extract the flavors and oils from the coffee beans. The resulting coffee is then infused with nitrogen gas, which dissolves into the liquid, creating a smooth, creamy texture and a distinctive cascading effect when poured.
The Science Behind Nitrogen Cold Brew
The science behind nitrogen cold brew lies in the properties of nitrogen gas. Nitrogen is a colorless, odorless, and tasteless gas that’s highly soluble in water. When nitrogen is infused into the cold brew coffee, it dissolves into the liquid, creating a smooth and creamy texture. The nitrogen also helps to bring out the natural flavors of the coffee, resulting in a more complex and nuanced taste experience.
The Benefits of Nitrogen Cold Brew
So, why choose nitrogen cold brew over traditional cold brew or hot-brewed coffee? Here are just a few benefits of this innovative brewing method:
- Smooth and creamy texture: The nitrogen infusion gives the coffee a velvety texture that’s similar to Guinness beer.
- Low acidity: Cold brew coffee is naturally low in acidity, making it a great choice for those who are sensitive to acidic flavors.
- Complex flavor profile: The nitrogen infusion helps to bring out the natural flavors of the coffee, resulting in a more complex and nuanced taste experience.
- Unique visual effect: The cascading effect of the nitrogen-infused coffee is a major draw for coffee shops and cafes looking to offer a unique and Instagram-worthy drink.
Equipment Needed to Make Nitrogen Cold Brew
To make nitrogen cold brew at home or in your coffee shop, you’ll need the following equipment:
- Cold brew coffee maker: You can use a traditional cold brew coffee maker or a large glass or plastic container with a fine-mesh strainer.
- Nitrogen gas tank: You’ll need a nitrogen gas tank to infuse the coffee with nitrogen. You can purchase a nitrogen gas tank online or at a local welding supply store.
- Regulator: A regulator is needed to control the flow of nitrogen gas from the tank to the coffee.
- Infusion vessel: You’ll need a vessel to infuse the coffee with nitrogen. This can be a large glass or plastic container with a lid.
- Siphon or pump: A siphon or pump is needed to transfer the coffee from the infusion vessel to a serving container.
Optional Equipment
- Coffee grinder: A coffee grinder is necessary to grind the coffee beans to the right consistency for cold brew.
- Scale: A scale is useful for measuring the coffee and water accurately.
- Timer: A timer can be used to ensure that the coffee steeps for the right amount of time.
Step-by-Step Guide to Making Nitrogen Cold Brew
Making nitrogen cold brew is a relatively simple process that requires some basic equipment and a bit of patience. Here’s a step-by-step guide to making nitrogen cold brew at home or in your coffee shop:
Step 1: Grind the Coffee
Grind the coffee beans to a medium-coarse grind. You’ll need about 1 cup of coffee for every 4 cups of water.
Step 2: Steep the Coffee
Combine the ground coffee and water in a large glass or plastic container. Stir the mixture to ensure that all of the coffee is saturated with water. Cover the container with a lid and let it steep in the refrigerator for at least 12 hours.
Step 3: Strain the Coffee
After the coffee has steeped, use a fine-mesh strainer to strain the liquid from the grounds. Discard the grounds and reserve the coffee.
Step 4: Infuse the Coffee with Nitrogen
Transfer the coffee to an infusion vessel and attach the regulator to the nitrogen gas tank. Open the valve on the regulator and slowly release the nitrogen gas into the coffee. You’ll start to see the coffee bubble and foam as the nitrogen is infused.
Step 5: Serve the Coffee
Once the coffee has been infused with nitrogen, use a siphon or pump to transfer it to a serving container. Pour the coffee slowly to create the cascading effect.

What is Nitrogen Cold Brew and how does it differ from traditional cold brew?
Nitrogen Cold Brew is a type of coffee that uses liquid nitrogen to rapidly chill and infuse the coffee grounds, resulting in a smoother and more full-bodied flavor. Unlike traditional cold brew, which involves steeping coarse-ground coffee beans in cold water for an extended period, Nitrogen Cold Brew uses a combination of cold water and liquid nitrogen to extract the flavors and oils from the coffee beans.
The use of liquid nitrogen in Nitrogen Cold Brew allows for a faster and more efficient brewing process, which helps to preserve the delicate flavors and aromas of the coffee. Additionally, the rapid chilling process helps to prevent the growth of bacteria and other microorganisms that can affect the flavor and quality of the coffee.
What are the benefits of using Nitrogen Cold Brew over traditional brewing methods?
One of the main benefits of using Nitrogen Cold Brew is its ability to produce a smoother and more full-bodied flavor. The rapid chilling process helps to extract the flavors and oils from the coffee beans more efficiently, resulting in a more complex and nuanced flavor profile. Additionally, the use of liquid nitrogen helps to preserve the delicate flavors and aromas of the coffee, which can be lost during traditional brewing methods.
Another benefit of Nitrogen Cold Brew is its convenience and speed. The brewing process is much faster than traditional cold brew, which can take several hours or even days to steep. With Nitrogen Cold Brew, you can have a delicious and high-quality cup of coffee in just a few minutes.
