Key Features Review

1. Spring Loaded Ceramic Burrs

The ceramic conical burrs are of very high-quality, similar to the kind you find in high-end electric grinders.

They are not only razor-sharp but also reduce heat build-up and are spring-loaded for stability. This combination of top features ensures a very even grind whilst maintaining all the delicious oils from your beans

2. Stainless Steel Body

A sturdy stainless steel exterior makes the Porlex Mini durable enough to be chucked in your backpack and generally bounced about without damaging the grinder mechanism.

3. Weighs only 8oz

If you’re going to be carrying a grinder around with you, you don’t want it to weigh you down. At only 8oz you’ll barely notice the extra weight.

4. Fits Inside the AeroPress

If AeroPress is your preferred brewing method, then this is a brilliant feature:

Your whole coffee setup can be fully self-contained making life easier and less messy, particularly when on the go. Plus it adds an extra layer of protection to your grinder.

5. 20g Bean Capacity

Yes, it is tiny – it’s called the Porlex MINI after all. But you can still brew 2 cups of coffee. So, it is not just for the solo coffee drinker.

Is the Porlex Mini Easy to Use?

Simplicity is the name of the game with Porlex.

To use, all you need to do is:

  • Take the top off
  • Put your coffee beans in
  • Replace the top
  • Then turn the handle until you no longer feel resistance

It really couldn’t be easier.

Changing the grind settings is also simple. There is a winged nut that is exposed when the grounds collector is removed. You simply turn it clockwise to get finer grounds and anti-clockwise for coarser grounds.

To help you on your way, it makes a small audible click for each setting. There are no markers to indicate what setting you are currently at, so switching between settings can be a bit of a pain. But it’s great if you always want the same grind size.

Design and Build Quality

Simple and functional designs are what Porlex specializes in. All of their hand grinders are built to last, made in their factory in Kagoshima, Japan.

The Mini measures 6″ tall by 2.3″ wide and 1.8″ deep.

Even for a manual grinder, this is very compact. The small size makes it perfect to pop in your bag or inside your AeroPress.

If you’re a traveler, the stainless steel body means it will easily survive being thrown around in backpacks or by careless luggage handlers. This is made even easier by the handle holder on the side, preventing knocks and preserving precious space.

Plus the ceramic burrs are of supreme quality, built to last no matter what you throw at it.

The spring-loaded mechanism around the burrs does a superb job at maintaining grind consistency and maintaining stability as you turn the handle.

Sure, the Porlex Mini isn’t winning any beauty contests, but it isn’t exactly ugly either. It’s practical and functional – and that’s all I want in a travel grinder.

Grind Consistency of the Porlex Mini

Thanks to excellent ceramic burrs and the spring mechanism which aids stability, the Porlex Mini has excellent grounds consistency. This consistency is maintained through most of its grinding range.

You will start to find a few issues at the very finest and very coarsest settings. These are not big issues, but they aren’t ideal either.

If you are looking to dial in a very specific espresso whilst on the road, it may not be accurate enough for that. However, if you’re using a Moka pot, pour over, AeroPress, drip, or even French press brewing method, the Porlex will do a fine job for you.

As the burrs are ceramic, you also need to take care not to chip them. This can happen if you’re grinding on the go and manage to get a little stone in there or buy low-quality beans which have harder beans than others in the bag. Luckily, replacement burrs are pretty easy to buy for the Porlex Mini.

Cleaning and Maintenance of Porlex Mini

Cleaning the Porlex Mini is made very simple thanks to how easy it is to take apart. All that is needed for cleaning is to use a soft brush on the burrs every week or 2, depending on usage. Doing so will ensure your grinder stays in top condition.

Thanks to the simplicity of design, disassembling and reassembling aren’t an issue at all. In fact, the whole process should take less than 15 minutes to complete.

Whilst having to take apart and clean your grinder is a pain it is necessary no matter which type of grinder you have. So having the process as simple as possible is the best you can hope for.

Final Thoughts on our Porlex Mini Review

If you are looking to freshly grind your coffee on the go, Porlex has created a superb grinder for you.

Thanks to the compact size and durable build materials, this grinder is ideal for backpacking or camping. In fact, it’s even small enough to fit inside your AeroPress coffee maker.

Finding good coffee when on the move can be a nightmare. So, having this little dynamo with you wherever you go is a godsend for any coffee lover.

The spring system keeps the burrs remarkably steady during grinding.

Whilst it isn’t ideal if you’re an espresso fanatic, it performs well for all other types of coffee makers.

Plus, the budget-friendly price means you can have one just for traveling and a different option for your kitchen.
