Machine Overview

Grinder 1, the 1Zpresso J-Max S, comes at a retail price of $159 and is tailored for intermediate users, which indicates a certain level of proficiency is required for optimal use. In contrast, Grinder 2, the Kingrinder K4, is priced lower at $119, making it more accessible for beginners, appealing to those just starting their coffee journey. Both grinders are manual, emphasizing a hands-on approach to espresso preparation. The difference in skill level signifies the J-Max S might offer advanced features catering to more experienced users.

Brewing Comparison

Both grinders employ a conical burr grinding method with a burr diameter of 48 mm. The J-Max S has a stepped adjustment with a finely tuned scale of 8.8 microns, allowing for precise control over the grind size. Meanwhile, the K4 also uses a stepped adjustment but has a coarser scale of 16 microns, which may limit the precision for some espresso enthusiasts. Both grinders utilize a single dose hopper and employ a manual dosing method, with the K4 having slightly higher retention at < .2 g versus the J-Max S at < 1 g, potentially affecting the consistency of your espresso shots.

Features Comparison

In terms of key features, the J-Max S stands out with its swappable burrs option, making it versatile for users wanting to change grind characteristics. Both grinders have specified grind ranges suited for espresso; however, only the J-Max S offers an adjustable RPM feature, although neither grinder has a motor, implying manual grinding speeds. The K4's design includes a threaded catch cup for easy cleanup, while the J-Max S features a magnetic catch cup, providing efficiency in capturing ground coffee. Overall, the J-Max S positions itself as the more advanced grinder, while the K4 serves as a user-friendly option for novices in espresso preparation.
