Machine Overview

The Kingrinder K4 and the 1Zpresso J-Max S are both manual espresso grinders priced at $119 and $159, respectively. The Kingrinder K4 is designed for beginners, making it an accessible option for those new to espresso making. In contrast, the 1Zpresso J-Max S targets intermediate users, offering enhanced features for a more experienced user base.

Brewing Comparison

In terms of grinding information, both grinders utilize a conical burr grinding method with a burr diameter of 48 mm. The K4 features a stepped adjustment with a grind range specifically for espresso and an adjustment scale of 16 microns, whereas the J-Max S also has a stepped adjustment but with a finer adjustment scale of 8.8 microns for more precision. Both grinders have a single dose hopper type and rely on manual dosing, but the J-Max S retains slightly more ground coffee with a retention of less than 1 gram compared to the K4's retention of less than 0.2 grams.

Features Comparison

Key features show some differences between the two grinders. The K4 has a grind range geared towards espresso and does not support swappable burrs, while the J-Max S offers swappable burrs, which can enhance versatility for different grinding needs. Additionally, neither grinder features adjustable RPMs, but both are capable of producing a consistent espresso grind, with the K4 grinding 18 grams in 60 seconds and the J-Max S achieving it in 40 seconds.
