1zpresso J-Max Grinder Build Quality and Design
The 1Zpresso J-Max, in its darker space gray color, immediately caught my eye with its sleek and premium feel. Grinding with the J-Max, the rubbery texture on the handle provides a comfortable grip, while the Chinese zodiac symbol adds a unique touch. The sandblasted, gunmetal finish reaffirms the quality every time I use it.
1zpresso grinders are all extremely compact. With a body size of 7 inches x 2.2 inches (18cm x 5.6cm) and a handle length of 5.5 inches (14 cm), the 1Zpresso J-Max fits comfortably in my hands, allowing for controlled and efficient grinding. Weighing in at 780g, it feels solid and substantial without being overly heavy.
The capacity to hold 35-40g of roasted beans is more than enough for my daily brewing needs, and it’s a convenience I’ve come to appreciate, especially when I’m making coffee for friends and family.
Grinding with the J-Max is a satisfying experience. The balance, the wooden knob, and the longer crank make grinding effortless. The magnetic dose cup is a clever addition, enabling a quicker workflow. However, I learned to handle it carefully after knocking it off a few times while grinding lighter roasts.
J Max Grind Adjustment and Grind Settings
The grind adjustment mechanism on the 1Zpresso J-Max is remarkably precise, allowing me to tailor the grind size to my exact preference. Each click on the J Max is equivalent to 8.8 microns of adjustment. With 10 clicks per number and 90 clicks per rotation, it offers close to stepless control in a stepped grinder.
The J-Max’s fine-tuning capabilities make it perfect for espresso, giving full control when dialing in new coffee beans. This fine tuning enabled me me experiment with different coffees with a variety of complex flavor profiles, clarity, and sweetness.
For filter coffee, the extensive adjustability can be a bit overwhelming at times, especially when many rotations are needed. While this ability to fine tune is great for espresso, it makes grinding for filter coffee a chore.
Yet, the ability of this manual grinder to go from very fine for Turkish coffee to coarser settings makes it versatile, even though it’s more focused on espresso. The redesigned 48mm conical burrs, coated in titanium, contribute to this precision, allowing me to enjoy my coffee exactly the way I like it, every single time.
J Max Grind Performance
The 1Zpresso J-Max shines in its grinding performance, especially when focusing on espresso. The 48mm conical burrs, coated in titanium, have been redesigned to make quick work of grinding, even at finer settings. The nearly stepless adjustment system, offering 8.8 microns per click, ensures a consistent and controlled particle size.
When grinding for Turkish coffee, the J-Max’s fine tuning capability is a game-changer, achieving an incredibly fine grind with ease. Moving on to the espresso grind, the ability to produce more fines contributes to complex flavor profiles, good clarity, and wonderful sweetness.
Moka pot and Aeropress are also doable with the J Max. However, any coarser and it starts to become extremely labor intensive. That’s not to say filter or French press is impossible with the J-Max; it is possible, it’s just not an enjoyable experience. I made 2 or 3 pour overs with it before I gave up as the tiny adjustments were too much.
If you brew a lot of filter coffee, then a grinder like the 1Zpresso JX Pro is a much better fit.
The burrs on the J Max provide a fast grind; I managed to grind 18 grams of coffee in under 30 seconds at an espresso setting, much faster than other hands grinders I own.
Pro Tip: Calibration is an essential aspect of maintaining the JMax’s performance, requiring attention approximately once a week. The process is simple and involves adjusting the grinder to bottom out at zero. This ensures that the J Max remains in alignment and continues to produce consistent grinds.
J Max Cleaning And Maintenance
Cleaning the 1Zpresso JMax grinder is a straightforward and hassle-free process, thanks in part to its design that allows for easy disassembly. By taking apart the grinder, I found it easy to access all the necessary components, from the burrs to the catch cup.
To clean the J Max, I use the accompanying brush and compressed air. I also wipe it down, to remove any old coffee oils and residual grinds.
The JMax’s design emphasizes user-friendly maintenance, making it suitable for both novices and experts. By cleaning it regularly I have found that it performs as well now as when I first got the grinder more than a year ago.
