Nitro coffee has earned its place among today’s most sought-after beverages. It’s an exciting opportunity for businesses – but also one that comes with unique operational challenges, especially for those still preparing it the traditional way.
Quality and freshness are bare minimums for consumers today. They also expect nitro coffee to be available on demand and served quickly. Whether a business meets these expectations largely depends on the nitro coffee system in place.
To find out what businesses should look for in such equipment, I spoke to Suhas Dwarakanath, the founder and director of India-based Benki Brewing Tools. Read on for his insights.
What is a nitro coffee system and why are more cafés investing in one?
A nitro coffee system infuses cold coffee with nitrogen under high pressure, producing a creamy, smooth drink with a cascading pour – without the need for sweeteners or additives.
Nitrogenation has its roots in the beer world, dating back about 60 years. Coffee only caught up in the early 2010s, but the setup is largely the same for both.
Cold coffee is usually placed in a sealed keg or container, after which nitrogen is introduced under high pressure. At the point of serving, the coffee passes through a specialised stout tap with tiny holes. This creates a beautiful cascading effect, topped with a creamy, foamy head.
As the pressure drops during pouring, millions of microscopic bubbles are released, resulting in the drink’s signature smooth, velvety mouthfeel. The taste and experience stand out because they require no sweeteners or additives.
That’s a big part of what attracts consumers to it, especially those chasing innovative flavour experiences. Many see it as a premium beverage, and the convenient formats it can arrive in add to its appeal. Beyond that, it has earned its place among functional beverages due to its perceived health benefits.
Suhas sees the same health-driven interest among Indian consumers. Many want to switch to black coffee for this reason, yet find themselves unable to.
“They do not have a habit of drinking black coffee and do not enjoy drinking it,” he adds.
Nitro coffee, however, has been changing that. “It sweetens the coffee naturally and makes it refreshing,” Suhas explains, “hence a lot of our customers started serving nitro coffees as their customers appreciated the taste profile.”
In the four years leading up to 2020, nitro cold coffee recorded a remarkable 904% increase in menu penetration. Consumer interest has not slowed since, and recent reports estimate that nitro coffee’s value will reach USD 144.5 million by 2030.
What equipment is essential in a nitro coffee system?
A nitro coffee system requires a keg or container, nitrogen tanks or chargers, and a specialised dispensing tap. Supporting components may include a dedicated nitrogen regulator, tap and gas lines, and refrigeration.
The keg-based system works by infusing cold coffee with nitrogen at high pressure inside an airtight refrigerated keg. When it’s time to pour, that same pressure drives the liquid through the nitro coffee dispenser.
Newer nitro coffee systems like the Hardtap take a different approach entirely. Cold coffee sits in a standard container without any pre-infusion or pressurisation. When you pull the tap handle, the dispenser draws in ambient air, separates the nitrogen from other gases, and infuses it directly into the liquid just before it reaches the glass.
Keg-based systems, by contrast, require a certain level of skill to set up and operate. For users like Suhas, this was a factor they couldn’t ignore.
“For us, ease of use was the number one priority as attrition is very high,” he explains. “We wanted to have a piece of equipment that is easy to train on and also clean.” Those qualities are evident in systems that use atmospheric nitrogen infusion, such as the Hardtap.
Its programmable digital dosing feature lets staff preset and dispense exact serving sizes every time at the touch of a button. This significantly reduces training requirements and helps ensure consistent pours regardless of who is serving.
“The second most important thing for us was consistency,” Suhas adds. The built-in automated cleaning programme rounds out the simplicity with self-running cycles that require minimal human involvement.
Atmospheric nitrogen infusion also eliminates bulky external gas tanks – one less piece of equipment to purchase, manage, and maintain. The Hardtap’s compact countertop design adds to its space-saving features. An in-line chilling system removes the need for external refrigeration, further cutting space and operational costs.
The savings on labour, space, maintenance, and nitrogen refills make a newer nitro coffee system a deserving upgrade over keg-based alternatives.
What features should businesses look for in a nitro coffee system?
Businesses should look for a nitro coffee system with automated dispensing, a built-in cleaning programme, and atmospheric nitrogen infusion – features that reduce labour, cut waste, and ensure consistency at scale.
Across all coffee categories, consumers expect high-quality beverages, quick service, on-demand availability, and consistency. A modern nitro coffee system can meet all of these expectations. For businesses, efficiency matters just as much.
A built-in sanitation programme, for instance, has a significant positive effect on time, labour costs, and safety standards.
“The ease of cleaning with the auto clean cycle has had the biggest impact as it is completely automated,” Suhas says.
He also points to the difference that other automated functions have made to day-to-day operations.
“The pour quality from glass to glass is very consistent regardless of who is operating the machine,” he explains. “It was a lifesaver.”
On the Hardtap’s intuitive touchscreen interface, users can programme and dispense up to four precise, customisable serving volumes. On older nitro coffee dispensers, the same process often leads to overpouring and spills – especially when staff members have varying skill levels.
Suhas credits this feature for much of the operational savings he’s experienced.
“Wastage has become absolutely nil as the machine can be calibrated for dispensing fixed amounts of liquid, because of which the ROI on the machine was much faster.”
When combined with atmospheric nitrogen infusion, these automated features eliminate the need for manual pouring and lengthy prep times. Staff – regardless of skill level – can dispense well-crafted drinks in seconds.
For a high-footfall outlet, that speed makes a real difference. With the Hardtap, businesses can dispense up to 50 litres per hour – upwards of 140 servings at 350ml portions. A system that’s compact, efficient, consistent, and versatile is a valuable investment for any business looking to stay ahead as nitro coffee grows.
Nitro coffee system: Key Takeaways
- Newer nitro coffee systems use atmospheric nitrogen infusion, removing the need for external gas tanks, refrigeration, and skilled operators – reducing costs across labour, space, and maintenance.
- Automated dispensing and cleaning programmes are the features with the greatest operational impact – eliminating waste, ensuring pour consistency, and requiring minimal staff training.
- Consumer demand for nitro coffee continues to grow – with the market projected to reach USD 144.5 million by 2030 – making investment in the right system increasingly commercially relevant.

Nitro coffee system: FAQ
What is the difference between a keg-based and an atmospheric nitro coffee system?
A keg-based system pre-infuses cold coffee with nitrogen inside a pressurised, refrigerated keg. An atmospheric system – like the Hardtap – stores coffee without pre-infusion and infuses nitrogen on demand at the point of pouring. The atmospheric approach requires less equipment, less skill, and lower running costs.
Why is consistency such a challenge with older nitro coffee dispensers?
Older nitro coffee dispensers rely on manual pouring, which means pour quality varies depending on staff skill and experience. Newer systems with programmable digital dosing remove that variable entirely – delivering the same result every time, at the touch of a button.
How fast can a modern nitro coffee system serve customers?
Systems like the Hardtap can dispense up to 50 litres per hour. At 350ml per serving, that’s more than 140 cups in an hour – making it a practical option for high-footfall outlets where speed of service matters.
