In the cold brew coffee business, time and efficiency are operational concerns that carry enough weight to determine profit or loss. A highly sought-after beverage that takes up to 24 hours to prepare can easily become a serious liability when the process is costly and inefficient.
With the best machine for cold brew coffee, everything changes. Preparation time drops dramatically, quality remains consistent, yields increase, and significant savings are achieved in labour and space.
To find the machine that delivers all that and more, I turned to three experts in the cold-brew space. Suhas Dwarakanath, Owner of Benki Brewing Tools and Founder of the Speciality Coffee Academy of India, discusses this alongside Hard Beans co-owners Maciej Duszak and Krzysztof Barabosz. Read on for their insights.
Why cold brew coffee demand is outpacing production capacity
Demand for cold brew coffee is outpacing production capacity because the category – expanding steadily since the early 2010s – is growing faster than most operations can handle with traditional equipment.
Maciej puts the scale of this growth into perspective. “This is the fastest growing segment in the coffee industry,” he explains. “It grows three times faster than the rest of the market, and it’s growing over 20% year-over-year.”
Part of what makes that growth sustainable is that cold brew is no longer a warm-weather category. It’s being consumed year-round, which means the pressure on production capacity doesn’t let up between seasons.
Keeping up with that kind of demand starts with the right machine for cold brew coffee. Suhas warns that cheap machines carry high maintenance costs, inconsistent results, and quality that lets customers down – leading to reputational damage.
“Opportunity cost – the reputational damage from letting customers down – is one of the biggest hidden costs an F&B operator can have,” he explains.
What types of machines for cold brew coffee are available?
The main types of cold brew coffee machines are immersion brewers and modern accelerated-extraction systems, and the differences in speed, output, and flexibility between them are significant.
Krzysztof recalls starting out with immersion methods and how long it would take to produce a full 20-litre batch. A beverage in such high demand cannot afford that kind of wait.
“With one immersion brewer, you can only make one type of coffee or one type of tea,” he explains. To offer different beverages at the same time, “you need three separate brewers,” he adds – and the space to match.
Consumers want speed, variety, and innovation – and older equipment makes that harder to deliver. On the other hand, modern machines address these challenges directly. Hardtank’s cold brew coffee machines, patented with accelerated cold extraction technology, produce a cold cup in under an hour.
“A standard batch of coffee is around 40 minutes with Hard Tank,” Maciej points out. “A standard batch of tea maybe even be as low as 15 minutes.”
That speed and versatility, paired with a compact design and higher output, mean you can handle multiple orders without needing several machines for cold brew coffee or too much space.
Modern cold brew systems allow you to scale production to demand. The Baby Hardtank produces around 4-5 litres per batch – roughly 13-16 servings at 300ml each. The Hardtank 20 steps up to 18-20 litres per batch, which is roughly 60-65 servings of the same size.
The flexibility this creates is best illustrated by a real operator: Black & White Coffee in Gdynia. The shop has built its reputation on cakes, but its cold-brew offering is just as considered.
Each morning, the owner uses a Baby Hard Tank to produce several batches of different single-origin cold brews, bottles them in 200ml glass bottles, and has them waiting in the fridge before the first customer walks in.

What features matter most in a machine for cold brew coffee?
The features that matter most in a machine for cold brew coffee are speed, yield efficiency, ease of use, versatility, and return on investment.
Start with yield. Using the same amount of coffee, Hard Tank produces considerably more output than traditional methods – and the difference shows up directly in cost per serving, which is twice as high with traditional equipment. That is a detail many operators only notice when they run the numbers.
Versatility compounds that advantage. “With one machine for cold brew coffee, you might be producing all sorts of different beverages one by one,” Maciej says.
A machine that also produces tea, cocktails, and infusions expands your menu without extra investment. “A cold brew tea is much cheaper to produce, and you don’t necessarily sell it much cheaper, if any, than cold coffee,” Maciej points out, which creates room for stronger margins using the same inputs.
Ease of use matters too. Since modern systems automate the process, Suhas says any member of staff can deliver consistent results without specialist training.
That simplicity extends to hygiene: with Hardtank equipment, the system cleans and sanitises itself at the press of a button, removing the labour, time, and risk of manual cleaning.
The return on investment reflects all of this. The cost per portion with Hardtank is less than half that of traditional methods, and the machine for cold brew coffee can pay for itself in as little as 73 days when used just once a day.
Maciej puts it: “There’s no espresso machine in this world, no coffee grinder in this world that will pay itself back so quickly if we only use it once a day.”
Hardtank backs that claim with a range built for operations of every size – from the compact Baby Hardtank to the high-output Hardtank 20. To learn more about the best machine for cold brew coffee, explore our equipment range here or contact a member of the Hardtank team.

Machine for cold brew coffee FAQ
What is the main advantage of a modern cold brew coffee machine over traditional methods?
Speed and yield efficiency. Traditional immersion methods can take up to 24 hours and produce significantly less output per batch. Modern systems like Hardtank use accelerated cold extraction technology to produce a cold cup in under an hour – and deliver roughly twice the yield from the same amount of coffee.
Can a machine for cold brew coffee produce different types of beverages?
Yes. Modern machines like Hardtank can produce cold brew coffee, tea, cocktails, and infusions in sequence using a single compact unit. Traditional immersion equipment requires a separate brewer for each beverage type, along with the additional space that this demands.
How quickly can a cold brew coffee machine pay for itself?
According to Hard Beans, the right machine can pay for itself in as little as 73 days when used just once a day. That is possible because modern systems like Hardtank cut the cost per portion to less than half that of traditional methods – making the per-cup margin strong enough to quickly recover the initial investment.
