Nitrogen Consumed vs. Nitrogen Spent: Unveiling the Hidden Nitrogen Math

When it comes to serving nitro cold brew coffee, most cafes rely on a keg system filled at a roastery or brewing facility.

This keg is then distributed to the cafe, where it is connected to a dispensing station alongside a backup cylinder of nitrogen.

While the process may seem straightforward, understanding the nitrogen consumption dynamics reveals a fascinating calculation.

Preserving Pressure: Nitrogen Gas in the Keg

As the nitro cold brew is dispensed from the keg, additional nitrogen gas is pumped back into the keg to maintain the necessary pressure of 30 psi (pounds per square inch).

This process ensures that the coffee remains pressurized and maintains its signature texture and mouthfeel.

The Nitrogen Math: A Surprising Revelation

The interesting part arises when we delve into the mathematics of nitrogen usage.

According to Murthy Tata, an industry expert, the average pint of nitro cold brew contains a minimal amount of nitrogen, less than two tablespoons.

However, due to the process of replenishing the keg’s pressure, a significant amount of nitrogen is expended.

For every pint of nitro cold brew served, approximately 96 tablespoons of nitrogen are “spent” refilling the keg.

In other words, while only two tablespoons of nitrogen are used to create the nitro-infused drink, around fifty tablespoons are needed to refill the keg during the dispensing process.

Assessing the Nitrogen Investment

Considering the significant nitrogen expenditure involved, it prompts us to question the worth of this investment.

Tata points out that only around 2% of all the energy that goes into producing, storing, and transporting nitrogen ends up in the final drink.

This revelation invites us to ponder whether this substantial nitrogen consumption aligns with the overall sustainability goals and environmental considerations.

Exploring Sustainable Alternatives

In light of the nitrogen consumption dynamics, seeking sustainable alternatives for nitro cold brew becomes paramount.

Innovative solutions that reduce nitrogen dependency while maintaining the desired characteristics of the beverage can contribute to a more eco-friendly approach.

The Oxygen Factor: How Air Exposure Impacts Coffee Flavor

When coffee beans come into contact with air, the presence of oxygen can have a detrimental effect on their flavor.

Oxygen acts as a flavor-zapping agent, causing coffee beans to emit different aromas and undergo degradation or oxidation of soluble compounds.

This oxidation process leads to the development of stale flavors and significantly diminishes the quality of even the finest coffees.

Understanding Flavor Degradation

The flavor of coffee is derived from a complex combination of chemical compounds naturally present in the beans.

However, when these compounds come in contact with air, they begin to oxidize, leading to the deterioration of the coffee’s flavor profile.

This oxidation process is particularly accelerated once the beans have been roasted, as the roasted coffee beans become more susceptible to oxygen damage, allowing the delicate coffee aromas to escape rapidly.

The Role of Oxygen in Aroma Degradation

When coffee beans are exposed to air, oxygen gradually degrades the aroma compounds present in the beans.

This process becomes more pronounced when the natural oils within the coffee beans are released.

As a result, the unique and desirable aromas that characterize freshly roasted coffee begin to dissipate, leading to a loss of flavor complexity and intensity.

Preserving Freshness: Whole Beans vs. Pre-ground Coffee

Whole coffee beans have a distinct advantage when it comes to maintaining freshness over pre-ground coffee.

This is because whole beans oxidize at a slower rate compared to pre-ground coffee.

By grinding coffee beans just before brewing, you can minimize the exposure of the coffee to oxygen and preserve its flavor for a longer period.

The Importance of Aroma Preservation

Two essential factors to consider when aiming for the peak flavor of freshly roasted coffee are the loss of aroma and the buildup of carbon dioxide.

The aroma compounds in coffee are delicate and vulnerable to oxidation, while the carbon dioxide released during the roasting process can act as a protective barrier against oxygen.

Therefore, it is crucial to find the right balance between aroma preservation and carbon dioxide release to achieve the best flavor experience.

The impact of oxygen on coffee flavor cannot be underestimated.

When coffee beans come in contact with air, the delicate chemical compounds that contribute to the coffee’s flavor begin to degrade and oxidize.

To enjoy the freshest and most flavorful coffee, it is recommended to opt for whole beans and grind them just before brewing, minimizing the exposure to oxygen and maximizing the aromatic experience.
