The Short Answer

Picopresso vs Nanopresso looks like a choice between two sizes of the same hand pump. It isn't. The Nanopresso is a pressurized brewer: a spring valve in its head builds resistance for you, so it copes with supermarket coffee and cheap grinders, and with an adapter it takes Nespresso capsules. The Picopresso is unpressurized. Its 52mm steel basket holds about twice the coffee and makes noticeably better espresso, but only if you feed it a fine, even grind.

  • Choose the Picopresso if you own (or will buy) a grinder that does true espresso and you want proper double shots on the road.
  • Choose the Nanopresso if you use pre-ground coffee or capsules, drink single shots, or want the cheaper, simpler brewer.

Every reviewer who pulled shots from both on the same day preferred the Picopresso. The one exception was a first-time user who underfilled its basket.

How We Compared Them

We haven't tested either brewer. This comparison draws on 16 YouTube videos and their comment sections, weighted like this:

  • Most weight: reviewers who brewed both side by side. Coffee Coach RYDE owned a Nanopresso for years, then pulled shots from both and measured them with a refractometer. The Coffee Chronicler reviewed the Nanopresso first and the Picopresso later. Lance Hedrick graded both in one tier list.
  • Solid weight: single-product reviews from independent channels: James Hoffmann (both brewers, in separate videos), European Coffee Trip, Matteo D'Ottavio, Kyle Rowsell, Cabeen's Coffee Corner and Morning Coffee.
  • Less weight: The Nomad Barista's direct comparison, because he consults for WACACO. GadgetViper links to WACACO as an affiliate, and the Chronicler's Picopresso was sent by WACACO. A novice taste test by ItsTheRealMrMaD counts only as a picture of what a first-timer gets.

Where only one person measured something, we name them. Claims from a single source that conflicted with others were dropped.

Shot Quality: Picopresso vs Nanopresso Side by Side

This is where the evidence is strongest. RYDE tasted his first Nanopresso shot as hollow and sour, and his meter agreed: a reading of about 6 against a target near 10. Grinding coarser lifted the Nanopresso to about 7.7. The Picopresso then read about 8.6 and tasted more balanced and cleaner. His conclusion was that the smaller brewer no longer has a place for anyone chasing flavor.

The Nomad Barista found the same gap in texture. His Picopresso shot was smoother, with a creamier body and fine tiger-striped crema. The Nanopresso shot was pleasant but had a coarser, bubblier foam that he blamed on the head valve. Hedrick's grades follow the same order: B for the Picopresso, C for the Nanopresso. The Chronicler, who wasn't impressed by the Nanopresso when he reviewed it, called the newer model better in almost every respect.

Hoffmann, carrying a flask of hot water around London for a day of portable brewing, found the Picopresso the most pocketable option that still made genuine espresso.

The dissent is worth knowing about. ItsTheRealMrMaD put 8g in each brewer and couldn't tell the shots apart. But 8g is roughly half a Picopresso dose. His shot leaked and showed no crema, which says more about dosing than about the machine.

Winner: Picopresso, clearly, once it's dosed and ground properly.

Basket and Dose: Single vs Double

The Nanopresso's stock basket takes 7 to 8g, a short single. Hedrick calls 10g a generous fill and notes the basket can't be swapped for anything better. The optional Barista Kit is sold as a 16g upgrade. Both the Nomad Barista and RYDE topped out around 11 to 12g, which RYDE describes as more than a single but short of a double.

The Picopresso's basket holds about 18g, and reviewers settle between 15 and 17g. That's the dose of a home espresso machine, and it can grow: Hedrick fitted WACACO's gauge and a precision basket to his, and 51mm tampers fit too. The basket is also bottomless, so you can watch the shot form and spot spraying, which our espresso channeling guide explains.

Anyone who drinks doubles or milk drinks should take the Picopresso here. The Nanopresso is fine if one small shot is what you want.

Your Grinder Decides More Than the Brewer

Most comparisons skip this, and it's the most practical difference. The Nanopresso's spring insert acts like the pressurized baskets on budget machines. Hoffmann points out that the stock setup is built around coarse supermarket coffee, and it still works with a basic hand mill. One commenter's Hario Mini Slim was fine on a Nanopresso but couldn't go fine enough for a Picopresso.

The Picopresso has nothing to hide a bad grind. WACACO's own guide points owners toward an Illy-style pre-ground, yet under GadgetViper's video six owners reported thin shots with no crema from exactly that, or from weak grinders. RYDE also found the reverse problem: a grind dialed in for the Picopresso choked his Nanopresso and tasted sour until he went coarser.

So if you don't own an espresso-capable grinder, the Nanopresso is the honest choice, or budget for a grinder first. The 1Zpresso range comes up more than any other brand across these videos. Our espresso grinder roundup and grind size chart cover what "espresso fine" means.

Heat: Both Need Boiling Water

Neither brewer heats anything, so both arrive at the cup cooler than a machine. Matteo D'Ottavio measured a Nanopresso shot at about 70 to 71°C in the cup from a cold start and about 77°C once the brewer was warm. Hoffmann thinks it can't reach the mid-90s at the puck and steers owners toward darker roasts.

The Picopresso needs the same routine, though the Chronicler found a single one-minute fill of hot water was enough for his. The trade-off is in your hand. The Nomad Barista says the Picopresso gets very hot after preheating, and Cabeen's and Morning Coffee both mention it. That's part of why the bundle we link adds a protective sleeve.

Tie. Plan on a kettle or a flask of near-boiling water either way.

Pumping Effort and Learning Curve

The Nomad Barista thinks the two take a similar amount of work, and found the Nanopresso's pre-infusion easier to push through its smaller dose. Others disagree on the Picopresso's side. Kyle Rowsell found it hard on the hands with fine grinds, and Cabeen's disliked the pumping enough to sell his. RYDE preferred the Picopresso's pump feel, calling it cleaner.

The Picopresso has three things to dial in: grind, dose and how fast you pump. GadgetViper suggests about one pump per second, aiming for around 40g in the cup after roughly 25 seconds. The Nanopresso has fewer variables with its insert in place. ItsTheRealMrMaD needed the manual and several minutes to put the Picopresso together, while the Nanopresso went together without fuss.

For beginners and anyone with weak hands, the Nanopresso takes this round.

Size, Weight and What Fits in the Case

On paper they weigh about the same, and the Chronicler calls their size comparable. RYDE puts it differently: his Nanopresso lives in a pocket, his Picopresso in a backpack. The Nomad Barista weighed the full Picopresso kit at around 470g.

Add-ons change this. Fitting the Barista Kit makes the Nanopresso longer, so it no longer fits its case. On the Picopresso, WACACO's pressure gauge adds about three inches according to Cabeen's, and the brewer then won't fit its case either. The Nanopresso has a cup built into its tank. The Picopresso doesn't, so you carry one.

Winner: Nanopresso, narrowly, for the cup and the slimmer shape.

Cleaning

The Nanopresso has more small parts than its size suggests: the insert, spring, screen and baskets. Hoffmann didn't enjoy cleaning it, and European Coffee Trip washes his with a drop of soap a couple of times weekly instead of following WACACO's much longer schedule.

The Picopresso is simpler to rinse. GadgetViper knocks out the puck, rinses the parts and pumps fresh water through for about ten seconds. Outdoors he dries everything with kitchen roll, and he removes the rubber cover before storing it so nothing stays damp. Owners of both warn about mould if parts are packed away wet.

Winner: Picopresso.

Capsules: The Nanopresso's Trump Card

The Picopresso takes ground coffee only. The Nanopresso has two capsule options. The NS adapter takes Nespresso Original capsules, and GadgetViper calls it easy mode: nothing to grind, almost nothing to clean. Hoffmann got far more crema from a capsule than from ground coffee, though the shot ran long at about 1:5. The DG Kit takes Dolce Gusto capsules; none of the reviewers tested it.

If you already keep a box of Nespresso capsules, this alone can settle it for the Nanopresso.

Price Tier

The Nanopresso is the cheaper brewer on its own. Add the Barista Kit and a case, and the Nomad Barista found the total went past what the Picopresso cost, which already includes its case, tamper and funnel. The Chronicler also described the Picopresso as only a little more expensive for a much better brewer. If you'd end up buying the Barista Kit, compare the two totals before you choose.

Where Reviewers Disagreed

Should Nanopresso owners upgrade? RYDE says yes, every one of them. Under the Chronicler's and GadgetViper's videos, though, several Nanopresso owners with the Barista Kit said theirs suited them fine for office coffee and camping. One liked owning four baskets so he could brew back to back. The split follows whether they grind fresh beans and care about the shot itself.

Does the pressurized Nanopresso taste worse? European Coffee Trip preferred his Nanopresso with the insert in. Hoffmann got poor results with and without it. Commenters who remove it report real crema, but only with a finer grind.

Owner-Reported Problems

Picopresso: a few gasket and piston failures after one to two and a half years in the comments; a lid seal that started leaking after a week's ski trip in one report; thin, crema-free shots from owners without a proper grinder; a hot body.

Nanopresso: seals that let coffee escape after years of use; one unit that died at six months; hot water leaking onto hands when screwing it together; a single shot that mug drinkers find gone in a sip.

Both have plenty of long-term owners too, from flight crew to people serving at sea.

Alternatives If Neither Fits

If you don't want to carry a kettle, WACACO's Pixapresso heats its own water and takes both ground coffee and capsules; our Pixapresso review covers what that costs in size and battery. If you want something even simpler than a Nanopresso for pre-ground coffee, the Minipresso GR2 review is the place to start. For lever, battery and hand-pump options side by side, our best portable espresso maker page ranks them all.

As a Gift: Which to Give

Picking a Picopresso or Nanopresso for someone else comes down to one question: do they grind their own beans? If they do, and fine enough for espresso, give the Picopresso. A hand grinder on their counter is a good sign. Owners under GadgetViper's video describe getting it from partners and family, and the Chronicler suggested it as a Christmas present. It looks good in its box and its case.

Give the Nanopresso to someone who drinks pre-ground coffee or Nespresso, or who just wants better coffee on a trip without learning anything new. Adding the NS adapter means it works on day one. If you can't find out whether they own a grinder, the Nanopresso is the safer gift.

Frequently Asked Questions

Is It Worth Paying More for the Picopresso?

Yes, if you have an espresso grinder. Every side-by-side test favored it, and RYDE's meter readings backed up the tasting. Without a capable grinder, the Picopresso's advantage mostly disappears.

Can the Picopresso Use Pre-Ground Coffee?

It can, but results are hit and miss. WACACO suggests a very fine pre-ground such as Illy, yet many owners got thin shots without crema that way. The Nanopresso is far more tolerant of pre-ground.

Does the Nanopresso With the Barista Kit Match the Picopresso?

Not quite. Reviewers fitted about 11 to 12g into the kit's larger basket, short of the Picopresso's dose, and the head still adds pressurized foam. The kit also lengthens the brewer past its case.

Which One Works With Nespresso Capsules?

Only the Nanopresso. Its NS adapter accepts Nespresso Original capsules. The Picopresso has no capsule option.

Which Is Easier to Clean?

The Picopresso, according to reviewers: rinse, flush with fresh water and dry. The Nanopresso has more small parts and benefits from a weekly soapy clean.

The Verdict

For most coffee drinkers who already grind their own beans, the Picopresso is the better buy. It makes a true double shot with real crema, and every reviewer who compared the two directly preferred it. It does demand a proper grinder, boiling water and some practice. Our Picopresso review covers its workflow and add-ons in detail.

Buy the Nanopresso if you use pre-ground coffee or capsules, want the cheaper and simpler brewer, or only drink single shots. Plan on the NS adapter or Barista Kit to match how you drink. Our Nanopresso review covers both add-ons.
