WACACO Minipresso GR Portable Espresso Machine Review

Essential Accessories:

• WACACO Minipresso Case
• WACACO Minipresso Kit
• Manual coffee grinder
• Travel kettle

When I first held the Minipresso GR, its thoughtful engineering immediately stood out. The sleek cylindrical design isn’t just for looks - it’s crafted for both durability and portability.

Core Specs:

• Dimensions: 175 x 70 x 60mm
• Weight: 360g (0.79 lbs)
• Pressure: 8 bar
• Water Tank: 70ml
• Coffee Basket: 8g
• Materials: BPA-free plastic, stainless steel internals

The build quality really shines through daily use. The matte black finish resists scratches while hiding coffee stains, and the food-grade plastic construction strikes that sweet spot between lightweight portability and rugged reliability. Each component fits together with satisfying precision, speaking to WACACO’s attention to detail.

I particularly appreciate the integrated design choices. The water tank indicators are crystal clear, the coffee basket holds the perfect dose for a single shot, and the built-in cup provides just the right capacity. The semi-automatic piston design delivers consistent pressure without requiring herculean effort.

While the Minipresso GR comes in just one color (black), WACACO offers variants for different brewing preferences:

• Minipresso NS: Uses Nespresso® capsules
• Minipresso CA: Compatible with Caffitaly® pods

The magic of the Minipresso GR lies in its clever semi-automatic piston system. Here’s my tried-and-true brewing process:

1. Prep Work:

• Grind fresh beans to fine espresso consistency
• Heat water to 90-96°C (194-205°F)

2. Loading:

• Unscrew the portafilter
• Add 8g ground coffee using the built-in scoop
• Tamp gently but firmly
• Reattach portafilter

3. Water Setup:

• Remove tank cap
• Fill to 70ml line with hot water
• Secure cap tightly

4. Brewing Magic:

• Unlock the piston
• Pump 6-8 times to build pressure
• Watch for initial drops
• Continue steady pumping (13-18 total)
• Stop when your shot is complete

The whole process takes about 1-2 minutes once you’re familiar with it. I’ve found the key is maintaining a steady pumping rhythm - rushing usually leads to uneven extraction.

What’s clever about the design is how it builds pressure gradually. Those first few pumps prime the system, while subsequent ones maintain the optimal 8 bars for proper extraction. The result? A properly extracted shot with impressive crema that would make many café machines jealous.

After months of daily use, here’s my honest assessment of where the Minipresso GR shines and where it could improve:

Major Strengths:

1. Espresso Quality

• Consistently produces rich shots with impressive crema
• 8 bars of pressure rivals professional machines
• Even extraction when technique is dialed in

2. Portability

• Fits easily in backpacks or larger pockets
• Surprisingly lightweight at 360g
• Sturdy enough for travel abuse

3. Versatility

• Works with any coffee beans
• No power needed
• Performs well at any altitude

4. Build Quality

• Solid construction that’s built to last
• Quality materials throughout
• Reliable mechanical operation

Notable Limitations:

1. Manual Effort

• Pumping can be tiring for some users
• Takes practice to develop proper technique
• Not ideal for multiple consecutive shots

2. Capacity Constraints

• Single-shot brewing only
• Small water reservoir
• Limited grounds capacity

3. Learning Curve

• Requires practice for optimal results
• Getting grind size right takes time
• Temperature management needs attention

4. Temperature Control

• No built-in heating
• Requires external hot water source
• Heat retention could be better

Having used this device extensively, I’ve found these pros and cons reflect real-world usage rather than just specs. The quality and portability genuinely impress, while the limitations mainly affect those needing to brew multiple shots quickly.

As someone who’s carried the Minipresso GR through airports, up mountains, and across continents, I can attest to its impressive travel-readiness.

Size and Weight:

I’ve found it particularly shines in scenarios like:

• Early morning hotel brewing before meetings
• Backcountry camping trips
• Long-haul flights (just need hot water)
• Office settings without good coffee options

The only real travel limitation I’ve encountered is the need for hot water, but between hotel kettles and camping stoves, this rarely poses a serious problem.

The Minipresso GR particularly shines for certain types of coffee enthusiasts. Based on extensive use and community feedback, here’s who’ll get the most value:
