It’s 7:23 AM on a Monday. You’re running late, craving your morning cold brew, but don’t have time to stop at your local coffee shop. Traditionally, making cold brew at home would mean planning 12-24 hours ahead—something you forgot to do yesterday.
Enter the Cumulus Coffee Machine, the appliance promising to revolutionize your morning ritual with cold brew in just minutes, not hours.
As someone who’s tested dozens of coffee makers over the years, I approached the Cumulus with healthy skepticism. Cold brew in under four minutes? It sounded too good to be true.
After three months of daily use, rigorous testing, and more caffeine than my doctor would approve of, I’m ready to deliver my comprehensive Cumulus Coffee Machine review.
Is this sleek, pod-based system truly the future of cold coffee, or just another trendy kitchen gadget destined for the back of your cabinet? Let’s dive in.

What is the Cumulus Coffee Machine?
The Cumulus Coffee Machine is a specialized brewing system that claims to produce authentic cold brew coffee in approximately 4 minutes—a process that traditionally takes 12-24 hours.
Launched in late 2024 by Cirrus Brewing Technologies (not to be confused with the cloud computing company), this machine quickly gained attention after celebrities like Kim Kardashian and tech influencers showcased it in their homes.
Unlike traditional cold brew methods that rely on time for extraction, the Cumulus uses a proprietary combination of pressure, temperature control, and specialized capsules to accelerate the brewing process dramatically.
The company calls this technology “RapidCold Extraction,” which they claim preserves the smooth, low-acidity profile that cold brew lovers crave while eliminating the lengthy wait time.
The pod-based system functions somewhat like a Nespresso machine but exclusively for cold coffee drinks. It offers various brew strengths and flavor profiles through its capsule system, which contains precisely ground coffee beans specifically formulated for cold extraction.
Traditional Cold Brew vs. Cumulus Method
| Brewing Method | Brew Time | Equipment Needed | Convenience Factor |
|---|---|---|---|
| Traditional Immersion | 12-24 hours | Mason jar, filter, coffee grounds | Low (requires planning) |
| Cold Drip Tower | 3-12 hours | Specialized equipment, coffee grounds | Low (complex setup) |
| Refrigerator Method | 8-12 hours | Container, filter, coffee grounds | Medium (simple but time-consuming) |
| Cumulus Machine | 3-4 minutes | Cumulus machine, water, capsule | High (nearly instant) |
Design and Build Quality
Aesthetic Appeal
The first thing you’ll notice about the Cumulus is its distinctly modern design. With clean lines, a minimalist interface, and a choice of matte black, brushed silver, or white finishes, it’s clearly designed to be a statement piece in contemporary kitchens.
The machine features a sleek LED touch display that illuminates only when in use, maintaining its streamlined appearance when idle.
The water reservoir has a unique cylindrical shape that resembles a cold brew tower—a clever nod to traditional brewing methods.
This transparent container not only serves its functional purpose but adds to the machine’s visual appeal, especially when illuminated by the subtle blue LED lights during the brewing process.
Size and Footprint
Let’s address the elephant in the room—or rather, the coffee machine in the kitchen. The Cumulus is not small. With dimensions of 12.5″ × 9″ × 15″, it requires significant counter space.
During my testing period, I had to rearrange my coffee station to accommodate this sizable appliance. If you have limited counter space, you’ll need to consider whether you can permanently dedicate this much real estate to a single-purpose machine.
That said, the footprint feels justified given the technology packed inside. The machine houses the water reservoir, brewing chamber, capsule system, and the proprietary cooling system that enables rapid cold brewing.
Setup and Ease of Use
Setting up the Cumulus is refreshingly straightforward. Out of the box, the machine requires minimal assembly—just insert the drip tray, fill the water reservoir, and plug it in. The machine runs a self-cleaning cycle upon first use, which takes about 5 minutes.
Day-to-day operation couldn’t be simpler:
1. Fill the water reservoir
2. Insert a Cumulus capsule
3. Select your brew strength (mild, medium, or bold)
4. Press brew
The entire process is intuitive, with the touch interface providing clear guidance. Even coffee brewing novices would have no trouble operating this machine.
How Well Does It Work? (Performance & Testing)
Speed of Brewing
The Cumulus Coffee Machine’s primary selling point is speed, and it delivers on this promise. In my tests, the machine consistently produced 8 oz of cold brew in 3 minutes and 45 seconds to 4 minutes and 10 seconds, depending on the strength selected. A 16 oz brew took approximately 7 minutes.
This is certainly impressive when compared to traditional cold brew methods that require overnight preparation. For busy professionals or last-minute cold coffee cravings, this time savings is genuinely valuable.
Coffee Quality
But speed means nothing if the coffee doesn’t taste good. So how does Cumulus cold brew actually taste?
The result is surprisingly authentic. The coffee produced has many of the hallmark characteristics of traditional cold brew:
- Low acidity
- Smooth mouthfeel
- Rich flavor profile with chocolate and caramel notes (depending on the capsule used)
- Minimal bitterness
In blind taste tests with five coffee enthusiasts, three couldn’t distinguish between 12-hour steeped cold brew and the Cumulus brew when using the “Ritual Medium Roast” capsule. The other two noted subtle differences but still rated the Cumulus brew favorably.
Where the Cumulus-brewed coffee differs slightly is in body—it’s not quite as full-bodied as traditional cold brew. It also lacks some of the deeper, more complex flavor notes that develop during longer extraction periods.
Temperature-wise, the coffee dispenses at approximately 41°F (5°C) when using refrigerated water, which is pleasantly cold without needing ice (though adding ice doesn’t significantly dilute the flavor).
Noise Level and Consistency
The machine operates at around 65-70 decibels during brewing—comparable to a normal conversation or dishwasher. It’s not silent, but it’s quiet enough that you could brew coffee early in the morning without waking household members in different rooms.
Consistency across brews is excellent. Once you find your preferred capsule and strength setting, you can expect nearly identical results each time—something that can be challenging with traditional cold brew methods.
Long-Term Testing Feedback
After using the machine daily for three months, I’ve noticed:
- No decrease in brewing efficiency
- The system remains easy to clean
- Capsules remain fresh when stored properly
- The machine consistently produces quality cold brew
One minor issue developed in the second month: the water reservoir began showing slight discoloration despite regular cleaning. This doesn’t affect functionality but is worth noting for aesthetic purposes.
Cumulus Coffee Capsules Review
The Cumulus operates exclusively with its proprietary capsules, which are larger than typical coffee pods and specifically formulated for cold extraction. Each capsule contains 18-22g of coffee, depending on the variety.
Capsule Variety
Cumulus currently offers six standard varieties, plus seasonal limited editions:
Sospeso Light Roast
- Flavor profile: Bright, citrusy with floral notes

Capsule Quality and Environmental Considerations
The capsules are made from a recyclable aluminum-polymer composite, similar to many espresso capsules on the market. Cumulus claims they are recyclable, though this requires separating the aluminum top from the polymer body—not the most convenient process.
For environmentally conscious consumers, this pod-based system does generate more waste than traditional cold brew methods. Cumulus has announced a recycling program launching in late 2025, but details remain limited.
Taste and Freshness
Each capsule is nitrogen-flushed and individually sealed, which helps preserve freshness. In my testing, capsules stored properly maintained their quality for the entire 3-month period.
The taste consistently outperforms pre-packaged cold brew concentrates and is comparable to freshly prepared cold brew from specialty coffee shops. The Ritual Medium Roast emerged as my clear favorite for daily drinking, while the Valor provided an excellent base for cold brew lattes and milk-based drinks.

Price and Value
With a retail price of $449.99, the Cumulus Coffee Machine represents a significant investment for a single-purpose appliance. Add to this the ongoing cost of capsules at approximately $1.80-$1.90 each, and the Cumulus becomes one of the more expensive ways to make cold brew coffee at home.
Let’s break down the cost comparison:
| Method | Initial Investment | Cost per Cup (8 oz) | Annual Cost (1 cup daily) |
|---|---|---|---|
| Café Cold Brew | $0 | $4.50-$6.00 | $1,642-$2,190 |
| Traditional Cold Brew | $20-$40 | $0.40-$0.60 | $146-$219 |
| Bottled Cold Brew | $0 | $3.50-$5.00 | $1,277-$1,825 |
| Cumulus System | $449.99 | $1.80-$1.90 | $657-$694 plus initial machine cost |
For daily cold brew drinkers currently purchasing from cafés, the Cumulus could actually save money over time, with the break-even point occurring around month 4-5 of ownership. However, compared to making traditional cold brew at home, the Cumulus is substantially more expensive.
The value question ultimately comes down to how much you value:
- The convenience of on-demand cold brew
- The time saved from not having to prepare ahead
- The consistency of results
- The aesthetic and experience of using a premium appliance
Comparison with Alternatives
Cumulus vs. Traditional Cold Brew Methods
Traditional cold brew methods, such as using a Toddy system ($40) or a simple Mason jar with filter ($10-15), produce excellent cold brew at a fraction of the cost. The trade-off is time—you’ll need to plan 12-24 hours ahead. For many coffee enthusiasts, this preparation becomes part of a relaxing routine.
Cumulus vs. Other Rapid Cold Brew Makers
The Dash Rapid Cold Brew System ($129) also promises faster cold brew, though it still takes about 15-20 minutes—significantly longer than the Cumulus but much faster than traditional methods. The Dash uses a different technology and doesn’t require proprietary capsules, allowing you to use your preferred coffee beans.
The GE Profile Craft Brewer ($349) offers both hot and cold brewing capabilities, making it more versatile than the Cumulus, though its cold brew function takes approximately 10-15 minutes.
Cumulus vs. Nitro Systems
Home nitro cold brew systems like the Royal Brew Nitro Cold Brew Coffee Maker ($179) provide the creamy, nitrogen-infused experience many cold brew lovers enjoy. These systems require you to prepare cold brew ahead of time but add the nitro element that the Cumulus lacks.

Final Verdict
After three months of daily use, the Cumulus Coffee Machine has earned a permanent place on my counter—but it may not be right for everyone.

- People with limited counter space
- Environmental activists concerned about pod waste
- Coffee experimenters who like to adjust variables and use different beans
Summary of Long-Term Experience
The Cumulus Coffee Machine delivers exactly what it promises: authentic-tasting cold brew coffee in minutes rather than hours. The convenience factor cannot be overstated—it truly transforms the cold brew experience from something that requires planning to an on-demand beverage option.
While the coffee doesn’t quite reach the depth and complexity of a perfectly crafted 18-hour cold brew from a specialty café, it comes remarkably close—certainly close enough for daily enjoyment. The consistency of results and the variety of flavor profiles available through the capsule system help justify the premium price point.
Is it worth the hype? For cold brew lovers who value convenience and consistency above all else, yes. For others, the calculus will depend on how much you’re willing to invest in shortening the path to your cold coffee fix.
