WACACO Nanopresso Portable Espresso Maker Review

Let’s see how the Nanopresso stacks up against similar portable options:

Essential Accessories:

• WACACO Nanopresso NS Adapter: Enables use of Nespresso®-compatible capsules
• WACACO Protective Case: Shields your investment during travel
• WACACO Barista Kit: Expands capacity for double shots (not currently in our catalog)
• Compact Manual Grinder: For the freshest possible coffee (check our grinder guide)

The Nanopresso packs serious espresso-making capability into an amazingly compact package. Let me break down what makes it special:

Core Specs:

• Length: 6.14 inches (15.6 cm)
• Diameter: 2.8 inches (7.1 cm)
• Weight: 11.8 oz (336g)
• Water Tank: 2.7 fl oz (80 ml)
• Coffee Capacity: 8g per shot
• Max Pressure: 18 bars

The standout feature is that patented pumping system. I’ve tested dozens of portable espresso makers, and none match the Nanopresso’s ability to generate professional-level pressure. This isn’t marketing fluff - you can actually feel the resistance build as you pump, and the results speak for themselves in the cup.

The build quality impresses too. The reinforced plastic construction strikes an ideal balance between durability and weight. After two years of regular use, including some rough camping trips, mine shows minimal wear. Every component feels precisely engineered, from the satisfying click of the portafilter lock to the smooth action of the piston.

Color options include the classic Charcoal Black, plus Red, Orange, and Yellow Patrol editions. I opted for basic black since it hides coffee stains better, but all finishes use the same high-grade materials.

What really sets the Nanopresso apart is how it manages to shrink full-sized espresso machine capabilities into something that fits in a jacket pocket. The engineering here is remarkable.

The magic of the Nanopresso lies in its clever mechanical design. Here’s my step-by-step guide after pulling hundreds of shots:

1. Prep Work

• Unscrew the portafilter
• Grind 8g of coffee to fine espresso consistency (slightly finer than typical)
• Heat water to just below boiling (195-205°F / 90-96°C)

2. Loading

• Fill the basket with coffee
• Tamp firmly using the bottom of the scoop
• Brush any stray grounds from the rim
• Thread the portafilter back on snugly

3. Adding Water

• Pop off the tank cap
• Fill to the line (80ml)
• Replace cap firmly

4. The Pull

• Unlock and extend the pump
• Hold over your cup
• Start with 2-3 slow pumps to build pressure
• Continue with steady, rhythmic pumps
• You’ll feel resistance increase as pressure builds
• Extract until your desired volume is reached (usually 25-35ml)

The whole process takes about a minute once you’re familiar with it. The first few attempts might be awkward, but the learning curve isn’t steep.

A neat trick I discovered: counting your pumps helps maintain consistency. I typically use 6-8 pumps for perfect extraction.

After extensive testing in various settings, here’s my honest assessment:

The Good Stuff:

• Remarkable Espresso: Achieves genuine crema and full flavor extraction
• True Portability: Lighter than my travel mug when empty
• Built to Last: Quality materials and solid construction
• No Power Needed: Works anywhere you have hot water
• Easy Clean-Up: Quick rinse and you’re done
• Versatile: Works with grounds or capsules (with adapter)
• Temperature Control: You choose your water temp
• Smart Design: Built-in cup and compact form factor

Room for Improvement:

• Single-Shot Limits: Makes one serving at a time
• Manual Effort: Pumping can feel like a workout
• Learning Curve: Takes practice to master
• Needs Hot Water: No built-in heating
• Small Parts: O-rings and filters need occasional replacement

Speaking from experience, the Nanopresso’s strengths far outweigh its limitations. I’ve used mine to pull shots everywhere from mountain campsites to airport lounges. The espresso quality consistently surprises coffee snobs who assume portable means compromised.

That said, be realistic about the manual operation. If you need to make multiple drinks quickly, you might get tired of pumping.

As someone who’s logged serious miles with the Nanopresso, I can vouch for its travel credentials:

Size & Weight:

• Fits easily in a daypack or large pocket
• Lighter than most reusable water bottles
• Compact enough for carry-on luggage

Durability:

• Survives being knocked around
• Weather-resistant construction
• No fragile glass components

Travel Perks:

• TSA-friendly design
• Easy to clean on the go
• Works with any heat source
• No batteries or charging needed

The optional carrying case adds protection without much bulk. I’ve found it especially useful for keeping parts together in a crowded backpack.

One road-tested tip: pack pre-measured coffee doses in small zip-lock bags. It makes brewing much easier when you’re on the move.

The only real travel limitation is needing hot water, but between hotel coffee makers, camp stoves, and friendly baristas, I’ve rarely found this to be an issue.

The Nanopresso is perfect for:

What’s the learning curve like? Most users get decent results within 3-5 tries. Mastery might take 15-20 shots.

Worth the investment? For anyone serious about portable espresso, yes. The quality and durability justify the price.

The WACACO Nanopresso represents a remarkable achievement in portable espresso making. During my extensive testing, it consistently delivered on its promise of cafe-quality espresso anywhere.

The build quality impresses daily - from the smooth pump action to the precise fit of components. While it requires some manual effort, the results rival much more expensive machines. The 18 bars of pressure isn’t just marketing - you can taste it in every well-extracted shot.

For travelers, outdoor enthusiasts, or anyone with limited space, the Nanopresso offers a no-compromise solution. The compact size belies its capabilities, and the durability holds up to regular use.

Sure, it has limitations. The single-shot capacity and manual operation won’t suit everyone. But for those willing to put in a little effort, it rewards you with exceptional espresso.

The Nanopresso truly shines in situations where other brewing methods fall short. Whether you’re camping in the wilderness or stuck in a hotel room, it brings the cafe experience anywhere.

After countless shots across various settings, I’m still impressed by this little device. It’s earned its place as both a travel companion and a daily driver for quality espresso.
