The Cumulus Coffee Machine review: a cold coffee setup that finally earns its counter space

I'm a hot coffee person by default. Cortados are my daily; espresso based coffees is where I feel most at home, and cold brew has always sat outside my regular rotation: something I'd order on a very hot day in summer, not something I'd actively seek out.

So when the Cumulus Coffee Machine landed on my counter, I came to it from the outside rather than as someone who'd been waiting years for exactly this machine to exist.

It promises on-demand nitro cold brew, still cold brew, and cold espresso in under a minute, and it's been running in my kitchen long enough now for me to have a real opinion rather than a first-week impression.

Short version: it's the machine that actually got me interested in cold coffee as a category, and for the right person, it's genuinely excellent. It also has enough caveats that I want to get them out of the way honestly, so this isn't a love letter, just an honest review.

Features I love

The nitro pour is in a league of its own

This is the thing that sold me on cold coffee in the first place, and it's the pour I keep wanting to make.

The Cumulus pulls nitrogen straight out of the air and infuses it into the brew as it dispenses. The result is a pour that looks closer to a Guinness than a coffee: a dense cascade of micro-bubbles settling into a thick, creamy head on top.

The texture on the tongue is velvety, the perceived acidity drops way down, and the whole drink takes on a rounder, gently sweet character even when I'm drinking it completely black.

I've had plenty of nitro cold brew from cafés and cans, and what the Cumulus puts out is comfortably my favorite of the three. Canned nitro always loses its foam within a minute or two, but this one stays lively in the glass long enough to actually enjoy it.

That's the feature I'd point to if someone asked me why the machine costs what it costs.

Proper on-demand cold coffee, no steeping, no ice

The other thing I didn't fully appreciate until I lived with it is that cold coffee at home has always required planning. Either you've got a jar of concentrate steeping in the fridge, or you're brewing hot and pouring over ice and accepting the dilution, or you're walking to a café.

The Cumulus collapses all of that into about 60 seconds once the water tank is chilled.

Day-to-day use is satisfying in a way I didn't expect. Lift the front tower, drop in a capsule, close it, twist the dial to Nitro, Still, or Cold Espresso, and press the brew button.

The water is already cold, the brew comes out cold, and nothing gets watered down because there's no ice in the glass.

After each drink the machine runs a quick automatic rinse cycle, and then simply push the Cumulus logo on the top to pop out the capsule holder, allowing you to easily remove the spent capsule.

The capsules themselves deserve a mention. They're recyclable aluminum rather than plastic, they feel substantial and properly made in the hand, and the branding on the lid is understated rather than novelty-coffee loud.

Loading something that actually looks like it belongs next to a $700 piece of kitchen equipment matters more than I'd have predicted.

I've worked through a decent chunk of the roast range by now, and the one I keep coming back to is the Ritual Medium roast; it tastes balanced, with just enough cocoa-and-nut depth to carry the nitro texture and hold its own against the foam.

For a daily cold-coffee drinker, the mental relief of never having to plan ahead is practical in a way that's hard to describe until you've had it for a while. The compressor is also quiet, much more subtle than the mini-fridge hum I half-expected.

The cold espresso quietly makes everything better

The 2 oz cold espresso setting is the one I underestimated at first. Neat, it's honestly a bit much for me: concentrated, thick, persistent crema, impressive but a lot to drink on its own when cold.

Where it earns its place in my routine is as a base. Poured over ice with a splash of milk, it makes an iced latte that holds its own against anything I'd get out of the house.

Into a shaker with vodka and a touch of coffee liqueur, it will pull a proper espresso martini without needing to fire up a hot espresso machine and then chill the shot.

One pod gives you enough for two cocktails, which is a nice touch when friends are over.

What could be improved

The footprint is the first thing I'd change. The 6-inch width is the headline number and it's genuinely slim, but the 19-inch depth is where it hides: this thing takes up real counter real estate front-to-back.

At 30-plus pounds, it's not something you'll cheerfully move in and out of a cupboard. If you have a compact kitchen, measure twice.

The proprietary pod system is the second one. I understand why it exists (the concentrate inside is doing specific work that loose grounds wouldn't replicate) but locking users into $2.50 to $2.90 per drink forever is a commitment on top of the initial price.

You can't use your favorite roaster, you can't grind your own beans, and if Cumulus ever changes the pod range or pricing, you're along for the ride.

It's also cold-only. I don't personally need hot coffee from it as I have my traditional Espresso machine and Nespresso coffee maker for that, but if you're in a two-coffee-drinker household where one of you wants hot mornings, this doesn't replace a second machine. It adds to the countertop, it doesn't simplify it.

Finally, the 15 to 20 minute initial water chill on the first brew of the day is worth knowing about. The workaround is easy (switch it on before you do anything else) but it's not push-button, get-coffee the way a Keurig or Nespresso machine is.

My verdict

The Cumulus Coffee Machine is a very good product at a genuinely uncomfortable price. Whether that adds up to a yes or a no depends entirely on how much cold coffee you drink and how much you value the premium nitro experience at home.

If you're a daily cold brew or nitro drinker, if you currently spend $5 or more on café visits several times a week, and if you have the counter space to commit to it, this is the closest thing to a home version of a café tap I've ever used.

The math works itself out in under a year for heavy users, and the daily quality-of-life improvement is real.

For my part, it hasn't replaced my hot coffee routine and I didn't expect it to. What it has done is turned me into someone who actually drinks cold coffee, which I wasn't before. The nitro in particular is something I actively look forward to on warm afternoons, after a run, or when I'd otherwise not have bothered with a second coffee at all.

If you're a casual cold-coffee drinker, if you also want hot coffee from the same machine, if you have a tight kitchen, or if the idea of being tied to proprietary pods feels like a red flag, this isn't the right pick. No shame in that. This is a specialized tool, not an everyday appliance, and it's priced accordingly.

For me, it earns its spot.
