As coffee lovers, we’re always on the lookout for the perfect cup. And for many of us, that perfect cup comes from Starbucks. But have you ever wondered what sets Starbucks coffee apart from the rest? One key factor is the use of nitrogen in their coffee. But what exactly does nitrogen do in Starbucks coffee, and how does it impact the flavor and quality of your morning brew?
What is Nitrogen and How is it Used in Coffee?
Nitrogen is a colorless, odorless gas that makes up about 78% of the Earth’s atmosphere. In the context of coffee, nitrogen is used to preserve the freshness and flavor of the beans. When coffee beans are exposed to oxygen, they begin to lose their flavor and aroma. This is because oxygen reacts with the coffee’s natural oils, causing them to break down and become stale. By replacing the oxygen in the coffee container with nitrogen, Starbucks is able to slow down this process and keep their coffee fresh for longer.
The Science of Nitrogen and Coffee
So, how exactly does nitrogen work its magic on coffee? It all comes down to the chemistry of coffee beans. Coffee beans contain a number of volatile compounds, including aldehydes, ketones, and esters. These compounds are responsible for the flavor and aroma of the coffee, but they’re also highly reactive. When they come into contact with oxygen, they begin to break down and form new compounds that are less flavorful and aromatic.
Nitrogen, on the other hand, is an inert gas. This means that it doesn’t react with the coffee’s volatile compounds, allowing them to remain intact and preserve the flavor and aroma of the coffee. By flushing the coffee container with nitrogen, Starbucks is able to remove the oxygen and prevent the breakdown of these compounds.
The Benefits of Nitrogen in Coffee
So, what are the benefits of using nitrogen in coffee? Here are just a few:
- Preserves flavor and aroma: By preventing the breakdown of the coffee’s volatile compounds, nitrogen helps to preserve the flavor and aroma of the coffee.
- Extends shelf life: By removing oxygen from the coffee container, nitrogen helps to extend the shelf life of the coffee.
- Improves texture: Nitrogen can also help to improve the texture of the coffee, making it feel smoother and more velvety in the mouth.
The Role of Nitrogen in Starbucks Coffee
So, how does Starbucks use nitrogen in their coffee? The company uses a process called “nitrogen flushing” to preserve the freshness and flavor of their coffee beans. Here’s how it works:
- Coffee beans are roasted and ground: Starbucks roasts and grinds their coffee beans in-house, using a proprietary blend of Arabica beans.
- Coffee is packaged in nitrogen-flushed containers: The ground coffee is then packaged in containers that have been flushed with nitrogen. This removes the oxygen from the container and prevents the breakdown of the coffee’s volatile compounds.
- Coffee is shipped to stores: The nitrogen-flushed containers are then shipped to Starbucks stores around the world, where they’re stored in a cool, dry place.
Nitrogen and the Perfect Brew
So, how does nitrogen impact the flavor and quality of your morning brew? Here are a few ways that nitrogen can affect the taste of your coffee:

What is the role of nitrogen in coffee brewing?
Nitrogen plays a crucial role in the coffee brewing process, particularly in the extraction of flavors and oils from the coffee beans. When nitrogen is infused into the coffee, it helps to extract the desirable flavors and oils from the coffee beans, resulting in a smoother and more balanced flavor. This is because nitrogen is a non-reactive gas that does not alter the chemical composition of the coffee, allowing the natural flavors to shine through.
The use of nitrogen in coffee brewing also helps to reduce the acidity of the coffee, resulting in a more palatable flavor. This is especially important for coffee beans that are naturally more acidic, as the nitrogen helps to balance out the flavors. Additionally, nitrogen helps to preserve the coffee’s natural aroma, resulting in a more fragrant and inviting brew.
How does Starbucks use nitrogen in their coffee brewing process?
Starbucks uses nitrogen in their coffee brewing process through a technique called nitrogen infusion. This involves infusing nitrogen gas into the coffee as it is being brewed, resulting in a smooth and creamy texture. The nitrogen infusion process helps to extract the desirable flavors and oils from the coffee beans, resulting in a more balanced and flavorful cup of coffee.
The use of nitrogen infusion in Starbucks’ coffee brewing process is a key factor in their signature coffee taste.
