The Guide to Hand/Manual Grinders: 1Zpresso, Timemore, MYM/MYY

Comments: 10↓ specifications & manual ↓

This would be a very brief post now, since I’m in a hurry to share my discovers before the end of the 11.11 sale on Aliexpress. I will update it late with more details and full review of 1Zpresso and Timemore grinders.

Straight to the facts. Manual coffee grinders are one of the rare espresso devices – except tampers, pitchers, knock-boxex and other accessories – that are worth buying at AliExpress. That’s because Chinese coffee grinder factories not simply produce OEM-products, which will be labeled under Hamilton Beach/Oster/whatever. They do all the marketing by themselsves and…

The secret is that you can buy an original 1Zpresso or Timemore grinders on AliExpress for less. And that’s not the case like when someone shows you cheaper copies or analogues of Western brands. No. When ordering something named like MYM54 or MYY47 coffee grinder… you are getting the very same 1Zpresso Q series grinder or new Timemore Chestnut C1. Personally checked!

MYM54 coffee frinder is... a 1Zpresso Q series grinder!

  1. Have recently purchased the JX-Pro.
    Playing around with it in the Turkish range its very easy to turn. Could only get to 3. No 2 or 1. But that is a range I have no use for. At 3 is is talc powder.
    Started at 40 for my Aeropress and am down to 34. It supprised me how much difference single steps in the grind can change the taste.
    The unit is easy to clean and dis and reassemble.

    • Thanks for your feedback! Did you experience the problem with beans feeding on the turkish grind?

      On the 1Zpresso Q1 I can select the fine enough grind level for turkish coffee, however burrs can’t “take in” beans. Finally I had to crash the beans before grinding for turkish.

    • Hi, could you tell me where did you purchase the jx-pro? I can’t seem to find it anywhere. Any help greatly appreciated.

  2. Hello,

    Thanks for posting this tip! I was looking for the 1SPRESO JE-PLUS. Do you have the reference to find it cheaper?

  3. Thanks for a post.
    Have a question about 1Zpresso Q2 (which seems to be a bit better than Q1). Does it grind well enough for espresso machines? Entry level ones like DeLonghi Delica / Eco 311 or Gaggia Viva? And what about grinding for Gaggia Classic Pro?

    I’m thinking about manual grinder mostly because I’m doing 3-4 cups top, some coffee with Hario dripper, rarely GAT moka pot, so I’m not afraid of manual work.
    And what about all the famous Comandante C40 grinder?

  4. Hello,
    I’ve bought a Timemore Chesnut and it comes with G1 burrs.
    Do you know where is it possible to order G1S or GS2 burrs for espresso ?
