If you’re a coffee enthusiast who appreciates innovation in every cup, join Hello 5 Coffee as we explore this captivating “beer-like” coffee beverage!
What is Nitro Coffee?
Nitro Coffee, also known as nitro cold brew or nitrogen-infused coffee, is a specialty beverage created by infusing cold brew coffee with nitrogen gas. This isn’t a random combination, but rather the result of extensive research and innovation in modern coffee brewing artistry.
The process begins with cold brew coffee – coffee that’s steeped cold at approximately 39°F (4°C) for an extended period of 12-24 hours. This cold brew is then infused with nitrogen (N2) – an inert, colorless, odorless gas that’s completely safe for consumption. Nitrogen comprises approximately 78% of Earth’s atmosphere and is a component of all living organisms, making it entirely benign for human health.
What makes Nitro Coffee truly special is the velvety foam layer on top of the glass, resembling a freshly poured draft beer. Unlike CO2 in carbonated beverages, nitrogen doesn’t fully dissolve into the coffee but instead creates tiny, micro-bubbles that produce a creamy texture and unique mouthfeel sensation on your palate.
The Irresistible Flavor of Nitro Cold Brew
Nitro Coffee delivers a sweet and balanced flavor profile with a full-bodied mouthfeel. The standout characteristic of this coffee is how nitrogen significantly reduces the natural bitterness and acidity of coffee, making the flavor remarkably smooth and approachable.
The fine foam layer on top isn’t just visually appealing – it contains natural sweetness from sugars and fats in the coffee that adhere to the nitrogen bubbles. When you take a sip, you’ll experience a cream-like smoothness with bold flavor that’s neither harsh nor sour. Many people compare this experience to enjoying a premium stout beer, but with pure coffee flavor.
Thanks to this unique texture, even those who aren’t coffee enthusiasts can easily fall in love with Nitro Coffee. You can enjoy this beverage without adding milk or sugar and still experience natural sweetness and creaminess.
The Origin Story of Nitro Coffee
Nitro Coffee first appeared in 2005, created by Mike McKim, owner of Cuvee Coffee in Austin, Texas. However, it wasn’t until 2012 that this coffee style truly created a sensation and spread worldwide at lightning speed.
The explosion of Nitro Coffee popularity was largely driven by two coffee industry giants: Starbucks and Dunkin’ Donuts. They introduced this unique beverage to their official menus, giving millions of consumers the opportunity to experience this novel flavor. From there, Nitro Coffee quickly became an icon of the third wave coffee movement, representing innovation and premium quality in the art of coffee brewing.
Today, you can find Nitro Coffee at most specialty coffee shops, supermarkets, and even vending machines, proving the lasting appeal of this beverage.
How to Make Nitro Coffee at Coffee Shops
At professional coffee shops, Nitro Coffee is brewed following strict protocols to ensure the highest quality. The process typically unfolds as follows:
Step 1: Prepare Cold Brew Coffee
Baristas begin by selecting premium coffee beans, typically varieties with bold flavors like Arabica or Robusta. Coffee is ground to a coarse setting of approximately 5-6, with a ratio of about 250g coffee per 1 liter of water.
The ground coffee is steeped in cold or room temperature water for 12-24 hours. This slow extraction process reduces acidity and bitterness while creating a bold, much smoother coffee flavor compared to traditional hot brewing methods.
Step 2: Filter and Store
After steeping for the appropriate time, the coffee is carefully filtered to completely remove all grounds. The cold brew concentrate is then stored in specialized stainless steel kegs, similar to those used for draft beer.
Step 3: Nitrogen Infusion
The coffee is kept under pressure of at least 40 psi to ensure consistent nitrogen saturation. There are two primary methods for nitrogen infusion:
- Using a dedicated nitrogen gas tank
- Using a Nitrogenator device – a machine that generates nitrogen from ambient air
Step 4: Serving
Nitro coffee is poured from a special tap, similar to a stout beer tap. When pouring, you’ll see a creamy foam layer gradually rise to the top, creating the signature beautiful appearance. Importantly, ice should not be added, as it will destroy the foam structure and dilute the unique flavor of nitro cold brew coffee.
How to Brew Nitro Coffee at Home
You can absolutely make Nitro Coffee at home with simple, readily available equipment. Here’s a detailed guide:
Required Equipment:
- Cold brew coffee maker (Hario or similar)
- Whipped cream dispenser
- Nitrogen (N2) cartridges (do not use CO2)
- Coarsely ground coffee
- Filtered cold water
Step-by-Step Instructions:
Step 1: Prepare cold brew by steeping 250g coarsely ground coffee in 1 liter of cold water, refrigerate for 16-24 hours.
Step 2: Filter the coffee through paper filters or cloth to completely remove all grounds.
Step 3: Pour approximately 250ml cold brew into the whipped cream dispenser (only fill 65-75% of the bottle capacity to leave space for gas).
Step 4: Install the nitrogen N2 cartridge into the dispenser, shake evenly for about 30 seconds to allow the gas to dissolve into the coffee.

Nitro Coffee Frequently Asked Questions
How Much Nitrogen is in a Cup of Nitro Coffee?
A cup of Nitro Coffee typically contains a small amount of nitrogen gas, just enough to create tiny bubbles and a fine foam layer. What’s special is that nitrogen doesn’t dissolve into coffee like CO2 in carbonated beverages, so it only creates a foaming effect without changing the overall flavor of the coffee.
The amount of nitrogen is precisely controlled through pressure (typically at 40 psi levels), ensuring just the right amount of foam – not too much to lose the smooth sensation, and not too little to lack the signature characteristic. When poured into a glass, approximately 20-30% of the volume is nitrogen foam, with the remainder being cold brew coffee.
Importantly, nitrogen is completely safe. It doesn’t cause any chemical reactions with compounds in coffee, maintaining natural flavor while enhancing the drinking experience.
Why Choose Nitrogen Gas for This Unique Coffee?
Nitrogen gas is chosen for its ability to create foam and smooth out coffee without altering the flavor. This is the core difference compared to other gases like CO2.
Comparison with CO2:
While CO2 (carbon dioxide) is commonly used in carbonated soft drinks, it’s not suitable for coffee. When CO2 dissolves in water, it forms carbonic acid, creating a sharp, sour taste similar to soda. This increases coffee acidity, going against the goal of creating a smooth, approachable cup of coffee.
The Superior Reasons for Nitrogen:
- Chemical Inertness: Nitrogen doesn’t react with compounds in coffee, preserving the original flavor
- Creates Fine Foam: Nitrogen gas creates extremely small, much finer bubbles compared to CO2
- Creamy Texture: The nitrogen foam layer provides a natural, rich sensation, similar to adding fresh cream
- Reduces Bitterness and Acidity: Nitrogen reduces the perception of bitterness and sourness without changing the coffee formula
- Absolutely Safe: Nitrogen comprises 78% of the air we breathe daily, completely harmless
Additionally, in the coffee industry, nitrogen is also used to preserve coffee beans, preventing oxidation and maintaining freshness longer.
