JavaPress Manual coffee grinder review

Instructions for use

JavaPress is extremely compact and easy to use, but its simplicity of construction does not come without the drawbacks.

Simply select the coarseness level, fill the grinder with beans, slide in the top to the bottom, then you are ready to go. Depending on the severity, it can take anywhere between 5 and 10 minutes to get the job done.

To select the roughness, tighten the setting knob to the right of fine grinds or loosen it to the left of coarse grinds that count the clicks as you rotate, with each left or right click representing a finer or coarser setting.

If you are used to an electric grinder, adapt to the manual procedure and take your time. This is why if you just occasionally have coffee here and there and see grinding as part of the coffee making ritual, this manual grinder may be the right choice.

On the other hand, if you have several people in the house who need a good morning coffee at the same time, then JavaPress immediately shows its limitations. On the other hand, this manual coffee grinder is ideal for camping trips.

The Conical Burr Grinder

One thing you immediately notice is the quality of the grind. If you come from an electric “knife grinder”, you will immediately see the difference in grinding consistency and consequent coffee taste.

Evenly ground beans is essential for the full extraction of the aroma, as well as the temperature at which the beans are ground. With the manual can grinder, the beans simply do not overheat and thus retain the full taste for a perfect brewing.

The JavaPress burr grinder consists of a fixed outer burr and a rotating central conical burr that is directly connected to a turn on which the upper crank is hinged. Turn the crank so you turn the cage inside in a very quiet way.

All of this works very well, and provided you do not have to paint for a cafe, the little JavaPress will do its job more than adequately. However, finer abrasions appear to be more uniform, while coarser abrasive sizes tend to be more inconsistent.

That said, if you continue every day for a few months, you may encounter few issues (more on these below).

Simplicity Vs practical

Because the grinder is so simply made, you just have a top and bottom part both of stainless steel. Once you have filled the beans, close the grinder by simply pushing the top into the bottom without screwing or locking mechanism.

This results in the top turning with the crank if you hold the bottom or bottom out, and the coffee grinder is spilled if you hold from above.

The solution is to hold the grinder with your hand over the two parts. Now the problem is that even this can be awkward because the stainless steel surface is so slippery that you need a strong grip to prevent the grinder from rotating in your hand.

If you have 10 minutes of elbow fat waiting for you, it will be both an elbow and a handle workout. The handle is also a bit small and can be a bit difficult to turn around if you have large hands.

Finally, if you use the same grinding roughness every time, JavaPress will do its job well and deliver a good grinding with decent consistency.

But if you like to switch between drip coffee, French press or espresso, it takes you a while to figure out the correct roughness every time. You can throw a few beans first to see how rough they are with a given setting and adjust it from there, but you would still have partially compromised the result.

Reliability of JavaPress manual coffee grinder

As mentioned at the beginning, there are few components in this coffee grinder that partly compromise and otherwise excellent setup (for the price).

The plastic bushings that hold the conical cage and the shaft connected to them are not strong enough for heavy use. By hard work I mean just using the grinder every day for your regular coffee / r, not for a sharing.

These plastic connectors are the weak link between the ceramic burr and the metal shaft, otherwise both very strong. When these plastic parts fail, they do so gradually rather than suddenly.

What happens is that the center degree begins to swing around and shift more to one side or the other of the external burr, resulting in progressive deterioration of the grinding consistency, which becomes less and less uniform over time.

Eventually, they may fail completely, making the grinder inefficient.

Who is JavaPresse manual coffee grinder suitable for?

As a result of the above point, this small manual coffee grinder is ideal for occasional or recreational use, such as camping or hiking. It is light, small and compact enough to fit in the smallest backpack, and it comes with a detachable handle.

In an outdoor situation, you only need a portable coffee machine and a hot water flask or gas stove to make your coffee beyond JavaPress.

You can also use it at home when silence is paramount, or if you want to switch to a manual bur grinder from an electric angle grinder when you want to improve the quality of your grinders and coffee maker.

More still, you can use JavaPress in an office environment so you can get a nice cup of coffee from freshly ground beans without disturbing your colleagues.

Just be prepared to not only use some elbow grease, which can become a bit of a task if done every day, but also for a possible drop in performance several months further down the line due to the plastic bushings being worn.
