Porlex Mini Stainless Steel Coffee Grinder Review

The Porlex Mini isn’t just another manual grinder - it’s a thoughtfully engineered tool that brings precision grinding to the palm of your hand. What strikes you first is its robust stainless steel body, which feels substantial despite weighing just 240g (8.5 oz). At 47mm x 130mm (1.85” x 5.12”), it’s remarkably compact - I can easily slip it into my jacket pocket or backpack side pouch.

The standout feature has to be the ceramic conical burrs. Unlike cheaper steel burrs that can dull quickly, these maintain their edge remarkably well. Through countless camping trips and daily use, I’ve noticed virtually no degradation in grind quality. The 13 distinct grind settings might seem limited compared to some competitors, but they cover all the bases from fine espresso to coarse French press grounds.

Key Specifications:

• Capacity: 20g (0.7 oz) of whole beans
• Materials:
• Body: Stainless steel
• Burrs: Ceramic conical
• Handle: Stainless steel with plastic knob
• Dimensions: 47mm diameter x 130mm height (1.85” x 5.12”)
• Weight: 240g (8.5 oz)
• Grind Settings: 13 adjustable positions
• Warranty: 1 year manufacturer warranty

What really sets the Porlex Mini apart is its thoughtful design touches. The detachable handle isn’t just convenient for storage - it’s positioned at the perfect height for comfortable grinding. The rubber grip around the body provides just enough texture to maintain control while grinding, even with morning-drowsy hands.

A clever design feature that often goes unmentioned: the way the burr assembly is mounted actually helps prevent wobble during grinding, which contributes to more consistent results. And yes, it really does fit inside an AeroPress tube - a compatibility that’s proven surprisingly useful during my own travels.

Getting great coffee from the Porlex Mini is surprisingly straightforward, though there are some tricks I’ve learned that make the process even smoother. Here’s the basic workflow:

First, unscrew the top lid and load up to 20g of beans into the hopper. The clear markings on the side help you eyeball the right amount, though I usually weigh my beans for consistency. Pop the lid back on, attach the handle, and you’re ready to start grinding.

The magic happens in those ceramic burrs - they’re set at an optimal angle that helps pull the beans through while maintaining consistency. You’ll want to keep a steady pace as you grind; I’ve found that a smooth, continuous motion works better than rapid turns. Expect to make about 150-200 rotations for a typical pour-over grind, which takes roughly 1-2 minutes depending on your beans and grind setting.

Speaking of settings, adjusting the grind is intuitive once you get the hang of it. The burr adjustment nut under the top lid clicks satisfyingly into each position. A full clockwise turn gets you to the finest setting, while counterclockwise loosens it for coarser grinds. I typically use:

• 2-3 clicks from tight for AeroPress
• 4-5 clicks for pour-over
• 8-9 clicks for French press

One thing I really appreciate is how the burrs are designed to maintain alignment even during coarse grinding - a common issue with lesser grinders that can lead to inconsistent particle size.

Let’s break down what makes the Porlex Mini shine and where it could use some improvement. Having used this grinder daily for several months, including a memorable three-week camping trip, I’ve gotten to know its quirks pretty well.

Strengths:

• Build Quality: The stainless steel construction feels bombproof. I’ve accidentally knocked it off my counter twice with zero damage.
• Grind Consistency: Those ceramic burrs deliver remarkably even particles, especially in the medium range perfect for pour-over.
• True Portability: Not just marketed as portable - it actually fits in a coat pocket or bag without being awkward.
• Silent Operation: A blessing for early risers or shared spaces. The grinding sound is barely audible from the next room.
• Low Maintenance: A quick brush-out between uses is all it needs; no special tools or complex cleaning required.
• AeroPress Compatibility: Fits inside the tube like it was designed for it - because it actually was.

Areas for Improvement:

• Limited Capacity: The 20g bean limit means grinding twice for larger batches. Fine for personal use, but tedious for groups.
• Manual Effort: It takes real effort, especially for finer grinds. Not ideal if you have hand strength issues.
• Grind Adjustment: Could be more precise - sometimes I find myself wanting a setting between two clicks.
• Handle Design: The plastic knob feels out of place on an otherwise premium device.

Real-World Experience: What really stands out in daily use is how the pros tend to outweigh the cons for most scenarios. Yes, grinding manually takes longer than using an electric grinder, but there’s something satisfying about the process. The grind consistency rivals much more expensive electric models, especially in the medium range that most brewing methods require.

That said, be realistic about your needs. If you regularly brew for multiple people or hate the idea of manual grinding, this might not be your best choice. But for solo brewers, travelers, or anyone who appreciates the ritual of manual coffee preparation, these minor drawbacks hardly detract from an otherwise excellent tool.

The Porlex Mini truly shines when it comes to portability - it’s not just marketing speak. As someone who’s carried this grinder through three continents, I can vouch for its travel-friendly design. The removable handle is a game-changer, reducing the packed length significantly. And at just 240g, it hardly registers in your luggage weight.

What really impresses me is how it handles the abuse of travel. The stainless steel body shrugs off the inevitable bumps and drops that come with life on the road. I’ve had mine rattling around in backpacks, suitcases, and even a kayak dry bag without issues.

The compact size (47mm x 130mm) means it fits just about anywhere. Tuck it into a shoe in your suitcase, slip it into an AeroPress, or drop it in a jacket pocket. The sealed design keeps coffee grounds contained - no mysterious brown dust appearing in your bag.

One clever detail: the grinder’s smooth exterior means it doesn’t catch on or damage other items in your bag. And unlike electric grinders, there’s no need to worry about batteries, charging, or voltage differences when traveling internationally.

The Porlex Mini is perfect for several types of coffee enthusiasts:

Frequent Travelers: If you’ve ever suffered through hotel room coffee, this grinder is your salvation. It packs easily and works anywhere, no power needed.

Outdoor Enthusiasts: Campers and hikers will appreciate its durability and compact size. It’s become an essential part of my backpacking kit, bringing cafe-quality coffee to remote campsites.

Space-Conscious Brewers: Living in a small apartment? The Porlex Mini takes up minimal counter space and tucks away easily in a drawer.

Manual Brewing Fans: Those who enjoy the ritual of hands-on coffee preparation will appreciate the control and connection to the process this grinder provides.

AeroPress Users: The ability to nest inside an AeroPress creates an unbeatable portable coffee kit. They’re a match made in coffee heaven.

While the Porlex Mini is excellent for many users, it’s not the right choice for everyone:

High-Volume Brewers: If you regularly make coffee for groups or need to grind large batches, the 20g capacity will feel limiting. Consider an electric grinder with a larger hopper.

Espresso Perfectionists: While it can grind fine enough for espresso, those seeking ultra-precise adjustments for espresso might want to look at dedicated espresso grinders.

Convenience Seekers: If you value speed and convenience above all, an electric grinder would be a better fit. Manual grinding takes time and effort.

Those with Hand Strength Issues: The manual grinding process requires grip strength and repeated motion that might not be comfortable for everyone.

Better alternatives for these users might include:

• JavaPresse Manual Coffee Grinder for larger capacity
• Electric burr grinders for convenience
• Dedicated espresso grinders for more precise adjustment

After extensive use, the Porlex Mini reveals why it’s earned such a loyal following. The ceramic burrs show minimal wear even after months of daily use - something I can’t say for cheaper grinders with steel burrs. The stainless steel body develops a subtle patina that adds character without compromising function.

The grind adjustment mechanism stays true, maintaining its settings without drifting. I’ve noticed the rubber grip might show slight wear over time, but it doesn’t affect functionality. The handle connection remains solid, though you might need to tighten it occasionally.

Perhaps most impressively, the grind consistency remains excellent over time. There’s no degradation in particle size uniformity, which directly translates to consistently good coffee in your cup.

One unexpected observation: the compact size actually encourages more frequent cleaning, as it’s so easy to disassemble and maintain. This likely contributes to its long-term reliability.

Keeping your Porlex Mini in top shape is straightforward, but there are some key practices I’ve learned:

Daily Care:

• Brush out loose grounds after each use
• Wipe the exterior with a dry cloth if needed
• Store in a dry place

Weekly Maintenance:

• Disassemble and thoroughly brush all parts
• Check the burr assembly for any trapped grounds
• Ensure the adjustment mechanism moves freely

Deep Cleaning (Monthly):

1. Fully disassemble all components
2. Use a dry brush to clean burrs thoroughly
3. Wipe internal surfaces with a clean, dry cloth
4. Check all seals and gaskets
5. Reassemble carefully, ensuring proper alignment

Common Issues and Solutions:

• Squeaking handle? A tiny drop of food-grade mineral oil on the shaft helps
• Inconsistent grind? Check for loose adjustment ring
• Stiff grinding? Clean out any trapped beans or grounds

Never use water to clean the burrs - it can promote rust and affect grind quality. A dedicated coffee grinder brush works best for cleaning.

The Porlex Mini’s environmental footprint is relatively small for a coffee tool. Its manual operation eliminates the energy consumption of electric grinders, and the durable construction means it won’t end up in a landfill anytime soon.

The stainless steel body is fully recyclable, and the ceramic burrs are made from natural materials. The minimal plastic components reduce environmental impact compared to grinders with plastic bodies.

The compact size means efficient shipping with a smaller carbon footprint. Additionally, by encouraging whole bean coffee purchase, it potentially reduces packaging waste compared to pre-ground coffee.

One overlooked aspect: its durability means less frequent replacement, reducing long-term resource consumption. The simple mechanical design also means fewer components that could fail and require replacement.

While Porlex doesn’t make specific environmental claims, the grinder’s design inherently supports sustainable coffee consumption through its longevity and minimal resource use.

The Porlex Mini sits in a sweet spot of value for what it delivers. The build quality alone justifies its price point - this isn’t a grinder you’ll need to replace annually like some cheaper alternatives.

The performance rivals electric grinders costing significantly more, especially in the medium grind range perfect for pour-over and AeroPress brewing. The ceramic burrs maintain their edge far longer than steel ones, adding to the long-term value.

Consider the versatility: it’s both a home grinder and a travel companion, potentially replacing the need for two separate grinders. The ability to fit inside an AeroPress adds another dimension of value for travelers.

While not the cheapest manual grinder available, its combination of durability, consistency, and portability makes it a sound investment for serious coffee enthusiasts. The fact that many users report years of reliable service suggests excellent return on investment.

After extensive use, I’ve discovered several ways to get the most from your Porlex Mini:

1. Smoother Grinding: Hold the grinder at a slight angle (about 15 degrees) while grinding - this helps beans feed into the burrs more efficiently.

2. Consistent Results: Count the number of rotations for your preferred grind size and brewing method. Write them down until they become second nature.

3. Travel Hack: Store beans inside the grinder during travel, but use a rubber band around the body to prevent accidental opening.

4. Static Reduction: Add 1-2 drops of water to your beans before grinding (the “Ross Droplet Technique”) to significantly reduce static and grind retention.

5. Speed Tip: Use your non-dominant hand to stabilize the grinder against a table or counter while grinding - this can make the process faster and more consistent.

These small adjustments can make a noticeable difference in your grinding experience and coffee quality.

Q: How long does it take to grind a full hopper? A: About 1-2 minutes for medium grind, longer for finer settings. Expect around 150-200 rotations for a typical pour-over grind.

Q: Can it grind fine enough for espresso? A: Yes, but it requires effort and might not achieve the ultra-fine consistency needed for professional espresso machines. It works well for AeroPress and moka pot brewing.

Q: How often should the burrs be replaced? A: With normal use, the ceramic burrs can last several years. Replace them if you notice significant degradation in grind consistency.

Q: Is it really worth getting over an electric grinder? A: For travel and portability, absolutely. For home use, it depends on your priorities - if you value control and don’t mind manual grinding, it’s an excellent choice.

Q: Can it grind for cold brew? A: Yes, it handles coarse grinds well, though you might need multiple batches for larger cold brew recipes.

Q: How quiet is it compared to electric grinders? A: Significantly quieter. You can easily grind early morning coffee without waking others in the house.

Q: Does it work well with light roasts? A: Yes, though they require slightly more effort to grind due to their density. The ceramic burrs handle them without issue.

After months of testing and countless cups of coffee ground across various settings and locations, the Porlex Mini has proven itself as a reliable companion for coffee enthusiasts who value quality and portability. While its 20g capacity might require a second round of grinding for larger batches, the trade-off in size and weight makes perfect sense for its intended use.

The grinder’s build quality is exceptional - something you notice every time you pick it up. That solid stainless steel construction isn’t just about durability; it provides the stability needed for consistent grinding. Those ceramic burrs keep performing admirably, maintaining their edge far longer than you’d expect.

What really stands out in daily use is how the Porlex Mini manages to be both practical and satisfying to use. The grinding action is smooth, the size is just right, and the results in the cup speak for themselves. Whether you’re brewing at home, camping in the wilderness, or making coffee in a hotel room, it delivers the kind of consistency that makes a noticeable difference in your final brew.

Sure, it’s not perfect - the small capacity and manual effort required won’t suit everyone. But for those who appreciate the ritual of manual brewing and need a reliable travel companion, the Porlex Mini hits a sweet spot between quality, portability, and value that’s hard to beat.
