What experts liked
The Porlex has a small set of ceramic burrs that produce a pretty consistent grind at the medium-fine setting and then becomes less and less consistent as it gets coarser.
- The Coffee Chronicler
The Porlex is also made of stainless steel, meaning it won’t crack when dropped like the Hario.
- New York Times Wirecutter
The Porlex Mini is the perfect camping grinder because its very durable as it is made from stainless steel, and its very portable as well, and requires no electricity to operate – just good, old-fashioned manual action.

Excellent grind consistency

The speed is simply amazing and the ease of grind makes the grinding process pleasant with little effort. This is due to a long steel handle that is crafted to connect well with the grinder.
- Kitchen Lola
Inside the Mini is a set of spring-loaded ceramic burrs that churn out a precise and consistent grind time, without overheating and ruining coffee beans. This consistency is rarely seen in a manual coffee grinder, and likely a major selling-point for the Porlex Mini.
- Your Coffee Buzz
The Porlex Mini has a removable handle which can be conveniently stored when traveling. Due to its small size it is a popular backpacking coffee grinder.
- Creators of Coffee
What experts didn't like
The only real drawback is that it’s small and as such takes longer to grind, but on the other hand that’s also a strength.
- The Coffee Chronicler
Don’t expect to use the Porlex as an affordable alternative to an electric grinder, especially if you ever want to brew more than one cup at a time.
- New York Times Wirecutter
The capacity is low
- Dripped Coffee
February 26, 2019 | Full review
Small capacity fit for one person or two at best
- Kitchen Lola
While it may lack a few of the features of the 1Z Grinder, at half the price it remains a very appealing alternative for many consumers.
- Your Coffee Buzz
Small 20g capacity

An Overview On Burr Grinders

Why buy a coffee grinder? Once you’ve had your first cup of coffee made with fresh ground beans, that question gets answered within a few sips. Within minutes of grinding, the aromas and oils locked inside a coffee bean start to lose their potency through contact with oxygen and air moisture. Simply put: The fresher the bean, the fresher the taste.

There are two general types of coffee grinders: those that use blades and those that grind the beans between burrs. Take a look behind the counter at any coffee shop, and you’ll most likely see a burr grinder, with good reason. These type of grinders work by pushing the coffee beans down between a pair of serrated plates, or “burrs.” The burrs then rotate, grinding the beans down to a particular size depending on the selected setting. The grounds are pushed out through the sides or bottom into a container, ready to be brewed.

By comparison, a blade grinder doesn’t technically grind at all. It slices the beans with tiny blades. While those blades might rotate faster or longer when the settings are adjusted, they won’t produce grounds of a uniform size. And even though that’s still better than pre-ground beans, the result isn’t ideal for true java aficionados. Smaller stray particles might slip through the filter in a French press, for example, or clog up an espresso machine.

All this means that yes, you might expect to pay a little more for a burr grinder. That cost can vary widely based on the variety of grind settings, capacity of the container and other bells and whistles.

There’s also material to consider. Increasingly, you’ll find that the burrs in burr grinders are made of stainless steel. The reasons are ones you might expect: Stainless steel is sharp and won’t corrode or rust. It will blunt over time, however, and also conducts heat — which can subtly affect the taste of the oils in your coffee.

This is why higher-end models may use ceramic burrs. While they aren’t as sharp, they will keep that edge longer and stay cool, no matter how fast the grinder runs.

DWYM Fun Fact

Many of us couldn’t function without our morning joe, but did you know that coffee can be used as fuel for more than just your job? In 2010, a team of British engineers converted a Volkswagen Scirocco into the Coffee Car Mark 1, whose converted combustion engine burned used coffee grounds. While it needed an entire 22-pound sack of beans to travel 55 miles, it nonetheless made an initial run from London to Manchester. Three years later, the updated Mark 2 coffee car broke 65 mph, a land speed record for any java-powered jalopy.

The Burr Grinder Buying Guide

  • When choosing a grinder, you’ll find models that advertise a number of different settings, allowing you to choose between near-microscopic variations in ground size. It’s a particular advantage of burr grinders, which can be adjusted in a more exacting way than their bladed counterparts. So what grind size do you need? It seems like every year there’s a new fad in coffee making, and your method of choice will determine the grind size. In general, you’ll want coarse grinds for French press, medium-size ones for traditional filter brewers or pour-over and fine grinds for espresso. If you only make coffee one way, congratulations! You might not need a huge variety of settings. Still, finding your perfect grind can be a zen part of the process. It all depends on your palate — and the amount of time you have to experiment.

  • Speaking of time, a grinder with a high storage capacity can save you a lot of it. It can be very convenient to stroll into the kitchen for your morning brew and find a reservoir of beans already in the hopper, waiting to be ground. Many grinders even have an automatic timer that will start the process before you even wake up. Just bear in mind that keeping beans out in the open too long can affect the taste.
  • If you’re buying a grinder at all, you care about the taste. Keep that taste consistent with frequent cleanings. How easy that is can vary greatly between grinders. Some are easy to take apart, and some require tools. Once you’ve got the burrs open and ready to be cleaned, you’ll want to use a brush or some other dry method.

  • Wipe-downs with a damp cloth are fine for the exterior, but you’ll typically want to keep the burrs as dry as possible, even if they’re stainless steel. If all that sounds like too much hassle, there are cleaning tablets that you can simply run through the grinder periodically, and they’ll take care of the majority of stray oil and grinds.
