When it comes to manual coffee grinders, the Porlex JP-30 rightly holds a privileged position in terms of sales and popularity. It is a conical grinder with a maximum capacity of 30 grams, whose most identifiable feature is its design. This is because this Porlex JP-30 – also known as Porlex Tall- is absolutely unmistakable. It is manufactured in Japan (see Porlex website), and this is evident in all the details.

The Porlex JP-30 was one of the first manual grinders to opt for a cylindrical shape made of stainless steel, achieving a final appearance halfway between minimalism and the most accentuated pragmatism. If you are looking for a small grinder, easy to store, easy to transport, attractive, resistant to the passage of time, you can be sure that you have already found it.

Parts of the Porlex JP30

As we say, the grinding wheels of the Porlex JP-30 are conical and are made of ceramic material. You can see how they look in the image above.

The one on the right is the upper wheel, and the one on the left is the lower wheel. Ceramic grinding wheels -not steel ones- are more durable and offer a higher resistance to heat, so they avoid the risk of overheating -and the consequent smell or taste of burning in our freshly ground grains.

Porlex JP-30: compact and minimalist design

When we hold the Porlex JP-30 with our left hand – or with the right, if we are left-handed – we will notice a sufficient grip to be able to operate the crank with the other hand without slipping or losing leverage with the movement. It is comfortable to handle.

In addition, the stainless steel gives it a very solid exterior, resistant to shocks and scratches, and is easy to clean. It hardly has any nooks and crannies or places that are difficult to access. The handle is also long enough and made of iron. In the following photograph, you can see the Porlex JP-30 separated by parts:

The operation of the Porlex JP-30 is the same as that of any other manual grinder: first, remove the top cover and pour in the coffee beans to be ground. Then put the lid back on and also put the handle back on. Start turning the handle until you no longer feel any resistance inside. The ground beans are now in the lower body of the grinder – open them to remove them and enjoy your freshly brewed coffee!

The grinder works effectively and is powerful enough to grind all the coffee (30 grams maximum capacity, enough for 2 or 3 cups) in just a minute or minute and a half without ending up with a sore arm.

Porlex JP-30: general characteristics

  • Maximum capacity: 30-40 grams of coffee
  • The grinding wheels are conical and made of ceramic material. Resistant to temperature increase and immune to rust.
  • All the components of the grinder are made of stainless steel, except the handle (which is made of iron) and the grinding wheels (which are ceramic).
  • With the exception of the grinding wheels, which are bolted on, all the elements of the grinder fit together under pressure. It is very easy to assemble and disassemble.
  • It can be adjusted to achieve a finer or coarser grind, depending on the type of coffee you are going to prepare.
  • The Porlex JP-30 is designed primarily for grinding roasted coffee beans. If you want to grind other types of material – such as nuts or other beans – make sure they do not contain any fats or oils that could damage their mechanism.
  • As a curiosity, its diameter fits perfectly inside the tube of the Aeropress, so you can grind the coffee and make it fall directly into the coffee machine.
  • Generous handle, about 15 centimetres long.
  • Weighs just over 300 grams.
  • Its dimensions are. 5 x 5 x 19 cms (width x depth x height).

Advantages of the Porlex JP-30

  • Excellent value for money.
  • Modern, attractive and very compact design. Fits anywhere and is perfect for travel or outdoor excursions.
  • The predominant presence of stainless steel in almost all its components.
  • Quite precise control of the grinding thickness, taking into account that it is a manual grinder.

Disadvantages of the Porlex JP-30

  • Like almost all manual grinders, it has a small capacity and is mainly used for individual grinding. It is not very practical if we need to grind large quantities of coffee.
  • Readjustments or calibrations are somewhat tricky. It takes some practice and knowledge of what you have in your hands to be able to carry them out successfully (NOTE: in the following section of this analysis we include a video-tutorial on this issue).
  • They come directly from Japan (Osaka, to be precise), so it may take several weeks to bring it home.

Why buy a Porlex JP-30?

The range of manual grinders on the market is really wide, and their characteristics are usually similar. The great advantage, in our opinion, of this Porlex JP-30 over other manual coffee grinders, is its combination of top quality materials (stainless steel body, ceramic grinding wheels) at an affordable price. It is a little more expensive than a conventional grinder, one of the basics, but it is still more affordable than a mid-range electric grinder. In short, a good alternative if we do not want to spend a lot of money and if we do not mind the extra work of having to turn the handle with the arm.

However, as we always say, if you need to obtain a very, very fine grind to prepare perfect espressos, then you’d better forget about the manuals and go for an electric grinder in good condition. For any other need, the Porlex JP-30 should be more than enough.

As alternative recommendations, you could take a look at the Zassenhaus Lima, a manual grinder very similar in design and performance.
