Cold brew coffee has grown steadily since going mainstream. It has become a recognised category alongside cold coffee staples such as iced lattes, Americanos, and frappes. Those drinks may hold the larger market share, but a 22% CAGR makes cold brew the fastest-growing of the lot.
In a market growing that fast, one of the factors that separates successful cafés from the rest is the cold brew machine they choose. A lot depends on it, including profitability, operational efficiency, and customer satisfaction, just to name a few.
To help you find a cold brew machine for cafés that will serve your business today and in the future, I spoke with Apsana Shaik. She is a Senior Content Writer at Growth Market Reports, a global market research and consulting firm. Read on for her insights

What types of cold brew machines for cafés are available?
Cafés can choose from traditional immersion systems, tower or drip systems, and modern automated cold brew machines that produce larger batches in under an hour.
For decades, immersion systems were the go-to choice. With this straightforward method, you steep coarse coffee grounds in cold or room-temperature water for 12 to 24 hours.
“For lower-volume cafés, traditional immersion systems remain a practical and cost-effective option,” Shaik explains. “However, for operators expecting growth, multiple locations, or higher daily throughput, modern automated cold brew systems offer several compelling advantages.”
Such older cold brew machines for cafés often run into limits of scale and capacity. Lower yield, higher labour costs, and poor overall efficiency compound the problem. Tower and drip systems, the other traditional alternative, work differently but share some of these drawbacks.
They use a slow-drip extraction method with a faster turnaround of four to six hours. Even so, low output, reliance on skilled labour, higher maintenance costs, and fragility make them less suited to cafés that prioritise efficiency, convenience, and ease of use.
Modern commercial café cold-brew equipment, such as the Baby Hardtank or Hardtank 20, tackles these challenges directly. Many models automate the process and use patented or advanced extraction technologies. They can produce a bigger batch in under an hour.
According to Shaik, the most attractive systems today are those designed around the shortcomings of older systems. “Consistent extraction quality. reduced labour requirements, faster production cycles, scalable batch volumes, and easier cleaning and sanitation,” she names their qualities.
Together, these factors significantly affect profitability. According to Shaik, the ROI from a newer cold brew machine with these capabilities far exceeds that of a basic setup. Ultimately, the decision boils down to that: efficiency and scalability.
“The strongest investment is often the cold brew machine for cafés that reduces operational complexity while providing enough capacity to support future growth without requiring replacement after only a few years,” she explains.
How much capacity does a cold brew machine for cafés need?
The machine should have sufficient capacity to outpace current demand by 25–50%. Base that figure on real sales data.
Commercial cold brew usually takes longer to prepare than hot or iced coffee, so meeting varying demand depends more on machine capacity and efficiency than staff numbers. The right starting point, then, is a reliable assessment of how much your café sells daily.
“Cold brew demand should be estimated using transaction data, beverage mix, seasonality, and expected business growth,” Shaik advises.
“A practical framework”, she adds, “is to evaluate average daily customer count, percentage of customers purchasing cold beverages, percentage of cold beverage sales represented by cold brew, seasonal fluctuations, delivery and takeaway demand, and planned menu expansion.”
Broader market trends are worth keeping an eye on as well. In the UK, for instance, 43% of consumers drink cold brew coffee at least once a month. In the US, 21% of the 32% of Americans who drink cold coffee report having it within the past week.
“Many operators underestimate future demand by focusing only on current sales,” Shaik warns. It’s a risky approach for a category that continues to experience strong growth across both foodservice and RTD channels.
Shaik therefore recommends building in a buffer of at least 25–50% above current demand. “Small cafés may require 1–3 gallons per day, mid-volume cafés often need 3–10 gallons per day, and high-volume urban locations may require 10–30 gallons or more daily,” she shares a broader guideline.
Such targets are well within reach with fully automated cold brew machines for cafés that finish a full cycle in under an hour. For instance, the Baby Hardtank produces 4 litres per batch, while the Hardtank 20 scales that up to 20 litres, both within the same timeframe.
From an investment perspective, Shaik says such “additional capacity often costs significantly less than replacing an undersized system in the future.” These systems are also more compact. They brew, chill, and serve all day without heavy staff involvement, reducing the risk of stockouts and cutting labour and space costs.

What else should you weigh when choosing a cold brew machine for cafés?
Beyond capacity, weigh labour efficiency, consistency, sanitation, food safety, menu flexibility, and scalability, including any future move into RTD production.
Equipment decisions for commercial cold brew machines for cafés stretch into every area that affects production and profitability. More key factors to weigh include labour efficiency, consistency, operational flexibility, sanitation, food safety, and scalability.
Labour is at the core of many of them. Costs, for instance, rise quickly when staff handle much of the preparation, serving, and cleaning. As Shaik points out, “Equipment that reduces preparation time, monitoring, and cleaning requirements can generate meaningful savings over its lifespan.”
Consistency is another casualty of an overly manual production process. “Equipment that minimises brewing variability can improve customer satisfaction while reducing waste and rework,” Shaik shares.
She adds that, “systems designed for efficient cleaning and hygienic production can reduce quality risks and improve operational confidence.” Where automation is lacking, these areas suffer as well, and the risks to food safety and operational integrity can be significant.
Beyond that, a cold brew machine for cafés that makes a range of cold coffees, not just cold brew, expands a café’s menu and revenue potential. This flexibility may be rare with older systems, but the newer ones handle it easily.
“Many modern systems support multiple brew strengths, concentrates, and menu applications,” Shaik points out.
All these capabilities drive growth, and the right café cold brew equipment should scale effortlessly, particularly for in-house production. But when a business enters the RTD cold brew market, this approach alone may not be enough. “For many growing coffee brands, the most effective strategy is a hybrid model,” Shaik shares.
Based on her experience, co-packing becomes a viable alternative when a brand outgrows its in-house operations. That shift can come through retail expansion, capacity limits, space constraints, rising labour costs, complex packaging regulations, or the need for consistency across locations.
Each approach has its merits, but the decision ultimately comes down to economics. “The right choice depends on growth objectives, production volume, and the role cold brew plays within the broader business strategy,” Shaik explains.
