WACACO Nanopresso Review: Worth It With the Right Add-Ons?

Our WACACO Nanopresso review comes down to this: the Nanopresso is worth it for travellers who want a small, decent shot of espresso from a 340g brewer with no battery, provided they preheat it and buy the add-on that fixes their main complaint. Across eight video reviews, the 18-bar figure on the box never decided anything. Temperature, the pressurized insert in the head and the tiny stock dose did. Most reviews skip all three, and that gap is what this page covers.

What Reviewers Agree On

Who the Nanopresso Suits (and Who It Doesn't)

It suits people who travel light and already have hot water on hand: hotel stays with a kettle, camping with a stove, long flights or ship postings. In the comments under James Hoffmann's review, owners describe daily use on navy ships, military deployments, triathlon trips and five years of nomadic travel. Matteo D'Ottavio's verdict sums it up: if your hotel room has a kettle, the Nanopresso is enough.

It doesn't suit someone who wants café-strength milk drinks from one shot, or a home brewer for lighter roasts. Hoffmann's view is blunt. If you already own a good espresso grinder, a manual lever machine at home will do far more with it, and outdoors he'd rather carry a flask of filter coffee. Lance Hedrick gave it a C in his budget manual espresso tier list for the small 39mm basket, the lack of a pressure gauge and a basket you can't upgrade, while still crediting how little it costs to get passable espresso.

Nanopresso Tips: The Workflow That Gets a Good Shot

Six of the eight reviewers raised preheating. Matteo measured it with a probe in a preheated cup: water pumped through a cold Nanopresso read about 70 to 71°C, and repeating straight away with a warm unit read about 77°C. His probe sat in the cup, so the brew itself was hotter, but the 7-degree gap is the point. A routine built from the reviews:

1. Preheat. Fill the tank with just-boiled water and pump it all through, as European Coffee Trip and The Nomad Barista both do. Warm the cup too.
2. Dose and level. About 8g in the stock basket. European Coffee Trip leaves 4 to 5mm of headspace above the tamped coffee so the shower screen seals. Keep the basket dry before dosing.
3. Fill to the line. About 80ml in the stock tank. Overfilling makes it spill when you screw it on, a problem Coffee Coach RYDE had on camera.
4. Pump steadily. Roughly one press per second; pumping fast can choke the puck. Owners in the comments say the heel of your palm gives steadier pressure than your thumb.
5. Use the leftover water. Top up the shot for a longer drink rather than forcing the whole tank through.

Pressurized or Non-Pressurized?

The head contains a small spring with a rubber or orange insert. Leave it in and the Nanopresso tolerates pre-ground supermarket coffee or a cheap grinder, at the cost of pale, slightly artificial crema. Take it out and you need a finer, more even grind, which is how GadgetViper ended up using his after a few months.

Reviewers split on which tastes better. European Coffee Trip found the non-pressurized shot more complex but thinner, and to his own surprise preferred the pressurized version. Hoffmann got poor results both ways with fresh grinds and saw leaking when he went finer. Coffee Coach RYDE found that a grind set for the Picopresso choked the Nanopresso and tasted sour; going coarser fixed it. The pattern: start with the insert in and a grind a little coarser than machine espresso, then remove it only once you have a grinder that can go fine evenly. If shots still taste sour, our espresso channeling guide covers the uneven-extraction side of the problem.

The Barista Kit, NS Adapter and DG Kit

Barista Kit. This is the add-on reviewers recommend most. It adds a ring that lengthens the body, two larger lidded baskets, a tamper, and a bigger tank and cup. Matteo and European Coffee Trip cite WACACO's figures of up to 16g of coffee and 120ml of water. In practice The Nomad Barista and RYDE managed about 11 to 12g, and owners in the comments say 16g is a squeeze. GadgetViper found the small tank gives one double and the large tank roughly two doubles' worth of water; he'd rather top up with hot water for an americano than push the whole tank through. The catch: with the ring fitted, the Nanopresso no longer fits its original case.

NS adapter. It lets the Nanopresso brew Nespresso Original-compatible capsules. Hoffmann's capsule shot had far more crema than his ground-coffee attempts, though at about a 1:5 ratio it drank more like a lungo. GadgetViper's verdict is that pods are the easy mode: drop one in, screw it shut, almost nothing to clean, ideal when you're brewing for a group. One owner warns that some capsules burst in it, so test your brand at home. If you need capsules, see our best Nespresso pods.

DG Kit. WACACO also sells a kit for Nescafé Dolce Gusto capsules with its own larger tank. None of the eight reviewers tested it. WACACO's own page warns that the flow rate and tank size mean drinks won't match a home Dolce Gusto machine, and some larger capsule drinks need the tank refilled several times. Buy it only if you already stock DG capsules.

What Else You Need to Buy

• A way to boil water. The Nanopresso has no heater. A hotel kettle works; outdoors you need a stove or a thermos. One commenter called this the deal breaker.
• A grinder, or capsules. With the insert in, pre-ground coffee works. For fresh beans, reviewers used hand grinders from a Hario ceramic mill to a Comandante. Our espresso grinder roundup covers options that reach espresso fineness.
• Darker-roast coffee. Hoffmann and Hedrick both point to darker roasts because the brew runs cool.
• A small scale (optional). Useful if you want to hit a steady ratio; our espresso-to-water ratio guide explains the numbers.

Owner-Reported Problems

• Hot water on your hands. European Coffee Trip had it leak onto his hand while screwing parts together, and owners under The Nomad Barista's video report the same. Hold it with a towel.
• Leaks and no pressure. Grinding too fine with the insert in causes side leaks or a stiff pump; a few owners say their unit never built pressure, which usually points to grind or dose.
• Seals wearing out. Long-term owners report coffee escaping at the sides after years of use, a broken plastic pump part, and one unit that died after six months. Others report years of daily use without trouble.
• Cleaning. It has lots of little parts. European Coffee Trip recommends a deep clean with a little soap once or twice a week rather than waiting for WACACO's 300-shot interval, and one commenter warns about mould if parts aren't dried.
• Shot size. Mug drinkers find a single shot gone in one sip, which is why so many buy the Barista Kit.

How It Compares

Picopresso. The Nomad Barista (a WACACO consultant), Coffee Coach RYDE and Lance Hedrick all rate the Picopresso's shot higher. It has a 52mm metal basket taking around 18g, a naked portafilter, and a funnel and tamper in the box. RYDE's refractometer readings backed up his tasting. The Nanopresso is lighter, simpler, more forgiving of grind and has a cup built in; the Picopresso needs a capable grinder. Read our Picopresso review if shot quality matters most.

OutIn Nano. In Matteo's side-by-side, the battery-powered OutIn Nano heats its own water and gave the same reading twice (81°C in his test, against the Nanopresso's 70 to 77°C), with a sweeter, heavier shot. It also weighs about 670g against 340g and costs roughly twice as much. Pick it if you'll only have cold water.

As a Gift

The Nanopresso gives well. It's one of the cheaper WACACO brewers, packs into its own case, and commenters under GadgetViper's videos mention getting the Nanopresso, Barista Kit and NS adapter as a Christmas present, or buying the set for cycling and motorbike trips. It makes most sense for a frequent flyer, camper, van traveller or anyone who complains about hotel coffee and drinks espresso or americanos.

Skip it for someone who wants a big mug of coffee, mostly drinks lattes from a machine, or won't carry hot water. For a coffee hobbyist who already owns a good grinder, the Picopresso is the better gift. If you're unsure whether they grind beans, add the NS adapter so it works with capsules on day one.

Frequently Asked Questions

Is the Nanopresso Worth It?

For travel, yes, if you preheat it and add the Barista Kit or NS adapter to suit how you drink. For home espresso or light roasts, reviewers say a manual lever machine or the Picopresso is the better use of the money.

Is the Nanopresso Real Espresso?

It can make a short, concentrated shot at espresso-like ratios, as European Coffee Trip showed at about 1:2.5. The stock pressurized head adds foamy crema, and the cooler brew means it won't match a good machine.

Can the Nanopresso Use Pre-Ground Coffee?

Yes. With the pressurized insert in place it's designed around pre-ground coffee, which Hoffmann notes is usually coarser than true espresso grind. Fresh coffee from a hand grinder tastes better once dialled in.

Does the Nanopresso Work With Nespresso Pods?

Only with the NS adapter, which takes Nespresso Original-compatible capsules. Reviewers found it the cleanest option outdoors, though shots run long.

Do You Need the Nanopresso Barista Kit?

If one 7 to 8g shot isn't enough for you, yes. It adds larger baskets and a bigger tank for doubles and americanos, but it makes the brewer longer than the original case.

Why Does My Nanopresso Leak?

Usually the grind is too fine for the pressurized head, or the tank was overfilled before screwing it on. Go slightly coarser, fill only to the line, and pump steadily. Leaks after years of use can mean worn seals.

WACACO Nanopresso Review: The Verdict

Buy the Nanopresso if you want the lightest practical way to make espresso-style shots on the road and you'll have boiling water. Budget for the Barista Kit if you drink doubles, or the NS adapter if you'd rather not grind. If you want the best possible shot from a hand pump and own a good grinder, spend more on the Picopresso.

How We Reviewed

We analysed eight YouTube reviews of the Nanopresso and its add-ons, plus several hundred viewer comments from owners. Five come from independent reviewers with no WACACO sponsorship (James Hoffmann, European Coffee Trip, Matteo D'Ottavio, Coffee Coach RYDE, Lance Hedrick); Hoffmann and European Coffee Trip bought their units, and RYDE had used his for years. GadgetViper's Barista Kit video uses WACACO affiliate links and his NS adapter was supplied by a UK retailer, so we treated his praise as enthusiast opinion. The Nomad Barista discloses consulting work for WACACO, so his comparison was weighted down and used mainly for specs and workflow. WACACO's own channel was excluded. Where only one reviewer measured something, such as Matteo's temperatures or RYDE's refractometer readings, we name them. Netspresso did not test the Nanopresso.
