1Zpresso is the new kid on the block when it comes to manual coffee grinders. This start up company is quickly making a name for itself for producing affordable and top quality grinders. So we are super excited to review the 1Zpresso J-series of hand grinders.
If you are on the market for a manual coffee grinder, the 1Zpresso grinders are outstanding! These grinders are extremely well built, have excellent grind consistency, and are quick and easy to use. The 1Zpresso JX is better for pour over, whereas the 1Zpresso JX Pro excels at both Espresso and Pour Over.
Why Buy A Manual Coffee Grinder?
There are several advantages to investing in a hand grinder over an automatic grinder. The first of these is price. Hand grinders offer far more bang for your buck. Because there are so few parts to a hand grinder, most of your money is going towards the quality and make of the burrs. Secondly, hand grinders offer portability. They tend to be far smaller and more durable than electric grinders which makes them great for travel. Finally, the process of using a hand grinder allows you to make a hobby, a passion, an art out of brewing. You get great satisfaction in grinding your own beans by hand.
Firstly, a lesson in pronunciation… the 1 in 1Zpresso is pronounced “eee” in Chinese, so 1Zpresso should be read as “Easypresso” not “One-Zed-Presso”.
Now that we have cleared that up… who is 1Zpresso? These guys are pretty new to the coffee scene, launching their company in 2017. They were founded by a bunch of specialty coffee lovers with engineering backgrounds. Based in Taiwan, their coffee brand focuses on producing premium hand grinders. They have quickly gained popularity in the Asian market, and we expect they will have a bright future in the coffee industry worldwide.
What Models Are Available?
The 1Zpresso Q2 grinder is their smallest grinder, built for travel and designed to fit perfectly inside an Aeropress. It has 38mm stainless steel burrs, making it quick and easy to grind coffee. This is an impressive grinder for the price and an excellent choice if you are looking for an entry level grinder.
We will go into the J-Series in more depth below but as a brief introduction there are two grinders in this series: the JX and JX-Pro. Both grinders have the same burr set, build quality and grind uniformity. They have a larger capacity making them great for Pour Over, French Press and Aeropress. While both grinders can grind fine enough for espresso, only the JX Pro has the micro-adjustment required to dial in espresso.
The 1Zpresso JE Plus is really designed for espresso. It features 47mm Italmil coated burrs, a large capacity and a sweet magnetic catch cup. This grinder allows you to precisely dial in espresso for a perfect shot. The Italmil coated burrs make them last longer.
The K-series grinders allow you to easily set your grind setting and switch between different grind settings. There are two grinders in the series, the K-Pro and K-Plus. They both have an external adjustment system, large capacity and 48mm stainless steel burrs. They offer exceptional grind quality. The K-Pro is a great all rounder grinder whereas the K-Plus is more tailored to espresso.
1Zpresso JX Pro
1Zpresso JX and JX-Pro Review
The 1Zpresso JX and JX-Pro are both excellently designed. With stainless steel bodies, dual-bearing shafts for greater stability and 48mm stainless steel burrs these babies are made to last. They have a sleek and modern look with a beautiful wooden knob on the handle making it easy to hold and turn. 1Zpresso have also included a rubber band to help you grip the grinder. Another benefit of the 1Zpresso range is that all the grinders are made to be disassembled without extra tools and don’t require recalibration once put back together. This thoughtful feature makes cleaning and maintenance a breeze. Overall both these grinders simply look and feel premium; you can tell they have been well made and are going to last.
As we mentioned above, a benefit of a hand grinder is its portability. However we must admit it would be a bit of a push to bring the 1Zpresso JX or JX-Pro on your travels. These grinders are simply big! The 1Zpresso JX (which is the smaller of the two) weighs 650g and the JX-Pro is even larger and weighs 780g. It’s safe to say these are not the most travel friendly grinders. If you are wanting a grinder more suitable the 1Zpresso Q2 is a lot more portable. Below is a picture of someone holding the 1Zpresso JX grinder for an indication to the size.
Grind Size Adjustment
It is at this point where the two grinders divide, utilizing different systems and therefore having a different range of grind settings. We found 1Zpresso’s grind adjustment guide here excellent, giving starting points for your different brewing methods.
The standard model has a simple stepped adjustment dial located under the main body of the grinder. To adjust the grind size you simply turn the dial clockwise for finer grinds and counter-clockwise for coarser. The dial clicks at each increment. There are 10 numbers on the dial and an additional 2 clicks between each number giving you 30 clicks per full rotation. Each click moves the burr by 0.025mm. There are about 120 grind settings allowing you to brew anything from espresso to French press, however it does not have the ability to fine tune your espresso grind setting.
The JX-Pro model has a more precise grind adjustment system allowing for the fine adjustments required to dial in an espresso shot. The grind adjustment dial is located on top of the grinder so you don’t have to take it apart to change the grind size. Like the 1Zpresso JX you turn the dial clockwise for finer grinds and counter-clockwise for coarser. The dial clicks at each increment. There are 10 numbers on the dial and an additional 3 clicks between each number giving you 40 clicks per full rotation. Each click moves the burr by 0.0125mm. With over 200 stepped settings you are able to make the micro adjustments required for espresso.
Anyone who has used a manual coffee grinder will know that grind speed is a game changer. Grinding beans by hand can be time consuming and tedious. However, 1Zpresso has made it seem like a walk in the park. To start with they have added bearings to the crank, to make turning smooth and easy to turn. Secondly the grind speed on both grinders is exceptional. The fast grind speed is largely due to the large 48mm stainless steel burrs which make short work of grinding. Surprisingly the 1Zpresso JX is faster than the JX-Pro. Grinding an 18g dose for pour over takes about 20 seconds with the JX and about 30 seconds with the JX-Pro.
The grind consistency produced by both the 1Zpresso JX and JX-Pro is excellent. Both grinders perform similarly with the main difference between them being the way you adjust the grind size and the sheer number of grind sizes available. They both produce an even grind consistency with few boulders or fines. This is particularly noticeable at the coarse level, which is the real test. Both these grinder outperform other entry level grinders and are up there with models such as the Comandante C40 and Helor 101.
As a side note some users have found the consistency is not as good when the grinder is new, creating a fine dust. This is because stainless steel burrs are very sharp at the beginning and need to be broken in. The consistency becomes more uniform after a few months of using.
Ease of Cleaning
As we mentioned above, 1Zpresso has designed all of their grinders to be able to be taken apart without the need for extra tools. This is extremely helpful when it comes to cleaning your grinder. 1Zpresso recommends you do a thorough clean once a month. To do this you take it apart and brush out any debris with a dry brush to clean (do not use water). You may use a damp cloth to help remove built up coffee oils but leave the parts to dry completely before reassembling.
1Zpresso JX vs 1Zpresso JX-Pro?
So which one is best for you? We recommend the 1Zpresso JX for those looking for a manual grinder for pour over or other manual brewing methods. It is cheaper, lighter and faster to use and should grind sufficiently for most manual brewing methods. If you are wanting a manual coffee grinder for espresso the 1Zpresso JX is the way to go, as it allows the fine micro-adjustments required to dial in a shot.
The Final Verdict
To wrap it up, if you are in the market for a manual hand grinder, either of these grinders from 1Zpresso will serve you well. 1Zpresso really has set a new standard for manual grinders. Their products excel in every category and they are extremely affordable (about 2-3 times cheaper than rivals). They grind consistently and quickly, are beautifully designed and built to last. What are you waiting for!
