The fast-rising demand for functional beverages, paired with a growing appetite for innovative recipes, has helped make nitro coffee one of the most sought-after drinks on the market today.
Any business looking to capitalise on this momentum would benefit from having a commercial nitro coffee machine. The right equipment delivers the creamy, velvety, foam-topped drink consumers expect – faster and more conveniently, without driving up labour or operational costs.
It all starts with knowing how to get the most out of such equipment. To find out more, I spoke to Ian McCluskey, co-founder of December Yaupon – an Austin-based beverage brand serving both canned and fresh yaupon nitro cold brew on tap.
What is nitro coffee, and why is it growing in popularity?
Nitro coffee is cold brew infused with nitrogen under pressure, producing a creamy texture, foamy head, and naturally sweet flavour without additives.
For a long time, stout beers were the go-to drink for a rich, foamy experience. That changed when nitrogen infusion crossed over into cold brew coffee. By the mid-2010s, nitro coffee had emerged as one of the most recognisable innovations in speciality coffee.
Most outlets serve it on tap, with that familiar cascading, foamy head any stout beer drinker would recognise. At December Yaupon, they serve it both on tap and in ready-to-drink formats – though it wasn’t the beverage that started it all.
“We originally focused on yaupon espresso but transitioned to yaupon nitro cold brew in cans because it is more scalable,” Ian explains.
That versatility allows businesses like his to move beyond café sales into retail distribution and events. The same commercial nitro coffee machine can also produce other nitro-based drinks, giving businesses an easy way to diversify their menu.
“For that reason, we decided to get a nitro kegerator in order to share the magic fresh from the tap with customers at markets, music festivals and more,” Ian explains. “There’s no better way to make connections with customers in person.”
Much of nitro coffee’s growth stems from its wellness appeal, as consumers increasingly turn to it as a natural, flavourful beverage with no additives or sweeteners. For yaupon, Ian points out that it is a descendant of yerba mate, “offering the same benefits with a richer, roasty flavour.”
Beyond functional benefits, a growing number of consumers are simply drawn to innovative drinks with a natural sweetness not present in many other beverages. Market reports estimate that the nitro coffee market will nearly quintuple in size by 2030.
How does a commercial nitro coffee machine work?
A commercial nitro coffee machine works by infusing nitrogen into cold brew under high pressure just before pouring. Nitrogen isn’t the easiest gas to dissolve in liquid, so higher pressure is required to achieve this, resulting in ultra-fine, smooth microbubbles.
On pouring, those bubbles rise and settle into a thick, foamy head that looks and feels like a well-poured stout beer.
“We load up the kegerator, kegs, nitrogen tank and accessories in our delivery van and drive to the location where we’ll be serving,” Ian explains of their mobile set-up. “When we arrive, we unload and set up for the event.”
Labour and some level of skill are needed to get everything running with such systems.
“There’s a bit of lifting, but the process is pretty simple overall,” he reassures. Keeping temperatures low is essential for minimising microbial activity, so as he puts it, “the kegerator is plugged in during the drive to stay cold.” After that, the system is ready to serve fresh nitro-based beverages.
“Once the event starts, we start pumping out fresh yaupon nitro cold brew for our customers,” he says. It is a system that delivers quality results – though not as fast or conveniently as a more modern commercial nitro coffee machine like the Hardtank Hardtap.
Many of the challenges associated with traditional systems can be addressed by a nitro coffee dispenser that uses atmospheric nitrogen infusion. Rather than relying on external nitrogen cylinders or cartridges, a machine like the Hardtap generates nitrogen infusion from ambient air within the dispensing system.
Older set-ups – with gas regulators and dedicated tap lines – take up considerable space and add to equipment costs. A nitro coffee dispenser with integrated atmospheric nitrogen infusion eliminates the need for this additional infrastructure.
The Hardtap goes a step further by allowing businesses to pair it with their existing cold brew system to improve service speed and convenience.
What should coffee shops look for in a commercial nitro coffee machine?
Coffee shops should look for a commercial nitro coffee machine that matches their operation’s scale, supports quick-connect pairings, and automates dispensing and sanitation to reduce human error.
For businesses using older set-ups, Ian says the choice of equipment comes down to the scale of the operation.
“It really depends on how many customers you’ll be serving and how much time you have.” He then adds, “If it’s a small event, get a portable dispenser that uses nitro chargers.” In venues where demand is high, he suggests businesses should “invest in a high-quality kegerator with multiple keg connections and multiple taps to keep up with lines.”
He also stresses the need for connector systems that allow effortless switching between keg formats. “Quick connect pairings are great for switching between homebrewed and commercial kegs if you need to do that,” he explains.
That said, a system’s reliance on manual processes still leaves room for spills, over-pouring, inconsistent pours, and safety risks from human error during cleaning. A modern nitro coffee dispenser like the Hardtap replaces manual interventions with automated dispensing and a built-in sanitation programme designed to reduce the risk of human error during cleaning and dispensing.
Staff – including those with no training – can pre-set dispensing volumes using Hardtap’s digital dosing control for consistent, waste-free pours. The built-in automated cleaning and sanitation programme ensures hygiene is never left to chance.
Ian adds that a versatile nitro cold brew machine offers the opportunity to build a broader customer base.
“For some events, we do cocktails as well,” he says. “This is key to introducing people to our product so they buy cans next time they see them at the store.”
Overall, the ideal nitro coffee setup combines consistency, precision, versatility, and ease of operation.
The Hardtap is built to deliver on each of these fronts – compact enough for any countertop, yet capable of serving classic cold brew, nitro coffees, and a range of other drinks such as iced tea, cascara, lemonade, cocktails, and mocktails, all with minimal human intervention and no external nitrogen tanks required.

How does a commercial nitro coffee machine work: FAQ
How does a commercial nitro coffee machine differ from a standard cold brew setup?
A commercial nitro coffee machine infuses nitrogen into cold brew under high pressure, creating ultra-fine microbubbles. A standard cold brew set-up does not use nitrogen infusion, so it cannot produce the creamy texture and foamy head that define nitro coffee.
What is atmospheric nitrogen infusion in a nitro coffee dispenser?
Atmospheric nitrogen infusion means the machine draws nitrogen directly from the surrounding air, rather than relying on external gas cylinders or cartridges. This eliminates bulky infrastructure, reduces equipment costs, and lowers the labour required to operate the system.
Can a commercial nitro coffee machine serve drinks other than nitro coffee?
Yes. A versatile commercial nitro coffee machine can serve a range of still and nitro-infused drinks, including iced tea, cascara, lemonade, cocktails, and mocktails – making it a practical investment for coffee shops, bars, hotels, and mobile operators.
