Guide and care for manual grinders 1Zpresso

Coffee on the go with 1Zpresso Q2

First of all, I want to introduce you to this little Q2. It's the smallest grinder in the 1Zpresso portfolio, which means it's perfect for on the go. It will get along very well with the AeroPress, into which it will fit perfectly, saving you space. Its capacity is only 15-20 grams, but that's ideal for making one cup of AeroPress coffee.

You can adjust the coarseness from underneath the grinding stones. The grinder is only suitable for filter coffee. However, its grind is consistent and perfectly stable. The Q2 is designed to be easily cleaned and then reassembled, plus there's no need to recalibrate afterwards.

Quality ground beans per filter with the 1Zpresso JX

TheJX will also grind your beans for filter coffee. However, it is fundamentally different from the Q2. Its grinding stones are larger (48 mm) and the hopper is also larger, which can hold upto 35 grams of ground coffee. The coarseness in this case is also set on the bottom of the grinding stones.

Higher Class 1Zpresso JX PRO

If the JX isn't enough for you, I have a more premium version of the JX PRO. The grinder can differentiate up to 200 levels of coarseness settings, making it suitable for the occasional espresso. One full turn makes 40 clicks versus the 30 you'll encounter with the regular version of the JX.

Sized to match the classic JX version, it is still suitable for travel. It also differs from the classic version in that the grind coarseness is set at the top near the hopper.

1Zpresso JE-Plus - the grinder for espresso lovers

Is making espresso your daily routine? Do you prepare espresso at home and on the go? And what would you say to:

  • 47 mm steel grinding stones
  • 200 levels of grinding coarseness
  • 40 g ground coffee container
  • Catch-up gantry for easy dosing into the portafilter

The JE - Plus offers you all this. Moreover, thanks to the use of high-quality materials, it will be your partner for years to come.

The1Zpresso K-Plus on-the-gogrinder

Are you a lover of espresso and filter coffee? Are you looking for a high-quality grinder for travel? If so, you'll get along with the K-Plus grinder. Travelling with the grinder will be easier thanks to the practical travel bag. Preparing coffee will be easier thanks to the possibility of setting 90 grinding coarseness.

You'll also enjoy thequick-dissasemblyfunction , which means you don't have to calibrate the grinder after cleaning. Make coffee for yourself, but feel free to make coffee for your friends too. With a capacity of 35-40 grams, you can grind up to 3 coffee beans.

1Zpresso grinder cleaning

You should clean your coffee grinder approximately every two weeks. Proper maintenance will help you extend the life of your grinder by several years.

The care of 1Zpresso grinders varies according to the specific models. However, the cleaning technique is fairly similar for a grinder with the same grind setting.

How to clean the 1Zpresso J-Max grinder?

  1. Remove the handle and ground coffee container and turn the adjustment ring clockwise approximately two clicks.
  2. Squeeze the grinding stones and turn counterclockwise to loosen the knurled nut.
  3. The grinding stones are then removed by squeezing in the centre. Remove the top ring cap and the top bearing, which is located inside the adjustment ring.
  4. The outer grinding stones can be removed by turning clockwise. However, removal of the adjusting ring is not recommended.
  5. Clean the grinder parts with a brush or the included blowing balloon.
  6. Position the parts so that the grinder fits neatly together. Fix the central shaft and the grinding stones together. Place the spring on the grinding stones and then the bearing cover.
  7. You can then insert the stones into the body of the grinder and the upper bearing into the adjustment ring.
  8. Now comes the tricky part, the flat side of the top bearing cap must match the flat side of the center shaft as well.
  9. Squeeze the grinding stones and tighten the knurled nut by turning clockwise until you feel resistance (don't over tighten or you will damage the grinding stones)

Cleaning the grinder 1ZPresso JX

  1. Separate the handle and the ground coffee container.
  2. Release the grinding stones by loosening the adjustment wheel.
  3. When you have unscrewed it completely, remove the grinding stones from the spring and bearing cap.
  4. Clean the grinding stones and other parts of the grinder with a brush.
  5. Then put them back together. And insert into the body of the grinder together with the spring.
  6. Tighten the stones using the adjusting wheel.
  7. All you have to do now is adjust the grinder.

Caring for the 1Zpresso JE-Plus

  1. As with any other grinder, start by removing the ground coffee container and handles.
  2. Then loosen the adjustment wheel by turning it counterclockwise while pushing down on the grinding stones from below.
  3. Remove the grinding stones by pressing the central shaft. Remove the sliding column from the upper ring cap where the upper bearing lies.
  4. The upper ring cap can be removed by turning it clockwise. Fit the retaining cap and remove the outer grinding stone by turning clockwise.
  5. The magnetic catch cover of the JE-Plus can be dismantled in three parts. Remove the magnetic clamping ring by turning counterclockwise. Then rotate counterclockwise to separate the closed catch container from the open catch container.
  6. Clean the grinder with a brush or blowing balloon.
  7. After cleaning, return the parts to their original condition to ensure proper functioning of the grinder. Before attaching the grinding stones to the body, the spring must be put on and then the bearing cover back on the grinding stones.
  8. There is a dot on the back of the sliding post. Place the sliding post (which connects the dot by the sliding post to the dot by the adjustment wheel) inside the hopper.
  9. Insert the sliding post into the upper ring cap and then into the upper bearing.
  10. Turn clockwise to tighten the knurled nut while pushing on the grinding stones.
  11. Now comes the tricky part, the flat side of the upper bearing cap must match the flat side of the centre shaft
  12. Tighten the adjusting wheel clockwise until you feel resistance.

Calibrating manual coffee grinders 1Zpresso

First you need to define the starting point of the grinding stones. First turn the adjustment wheel clockwise until it reaches the stop. You can tell the point by feeling the resistance as you turn the crank.

Calibration, like cleaning, varies according to the part where the grinding coarseness is set.

Calibration of mills with internal coarseness adjustment

If your coffee corner has a Q2, JX or JE model grinder, calibration is very simple in your case. The numbers on the wheel are for counting how many steps you have changed the coarseness, so the starting point does not have to be 0.

So just use the clockwise rotation of the adjustment wheel to get to the point where the crank will spontaneously rotate.

Calibration of grinders with external coarseness adjustment

For mills whose coarseness is adjusted externally, there is still a difference between models. K-series mills are adjusted as follows.

  1. Before inserting the internal grinding stone into the grinder, tighten the adjustment wheel counterclockwise to the stop and then to position 0. Ensure that the inner gap is completely closed and insert the grinding stone and other parts into the grinder.
  2. Push the grinding stone fully underneath and tighten the knurled nut.
  3. The grinder should now be calibrated. If the red dot still passes through the number 0, loosen the adjustment wheel a little and repeat step 2 until the red dot aligns with the number 0.

Calibrate the J-Max grinder by following these steps:

  1. The starting point should be where the 0 aligns with the scale mark and the bottom edge of the adjustment wheel ring touches the first step of the scale.
  2. Tighten or loosen the knurled nut while pressing the grinding stone from the bottom to set the starting point at 0.

The total number of revolutions from the start is four and a half. However, the starting point may vary by ±10 clicks based on how much you tightened the nut during calibration.

Calibration with the grind coarseness setting at the top

In general, this type of adjustment works the same as the internal adjustment. So the numbers on the dial are designed to count the number of steps you have turned, and so the start does not have to be at 0. However, if you want to set the start point to 0, do the following:

  1. When the grinder is fully tightened but pointing to 1, 2. or 3, take the setting wheel off (by turning it counterclockwise)
  2. Turn the knurled nut counterclockwise 1, 2, or 3 clicks.
  3. Screw the adjustment wheel back on and the starting point should be at 0 again.
