Machine Overview

Grinder 1 is the 1Zpresso J-Max S, priced at $159, designed for an intermediate skill level. In contrast, Grinder 2 is the Kingrinder K2, available at a more affordable price of $79, and aimed at beginner users. Both are manual grinders, making them suitable for users who enjoy the hand-crank experience. The difference in pricing and target skill level may appeal to different segments of coffee enthusiasts.

Brewing Comparison

In terms of grinding information, both grinders utilize a conical burr design with a burr diameter of 48 mm. The J-Max S features a stepped adjustment, allowing precise grind size changes with an adjustment scale of 8.8 microns, and has a single-dose hopper for easy dosing. On the other hand, the K2 also employs a stepped adjustment, but with a coarser adjustment scale of 18 microns and a single-dose hopper for similarly efficient dosing. The J-Max S boasts lower retention of less than 1 gram, compared to the K2’s retention of less than 0.2 grams, indicating slight advantages in grind freshness.

Features Comparison

Regarding key features, the J-Max S allows for swappable burrs, offering more customization options for users. The grind range for the J-Max S is limited to espresso, while the K2 has a broader grind range capable of handling both pour-over and espresso. Neither grinder has adjustable RPM settings, which limits their adaptability in terms of grinding speed. These distinctions in features highlight the specific advantages and limitations of each grinder in catering to different user preferences.
