With years of experience running a café, Wayne has mastered the art of coffee brewing and is passionate about sharing his knowledge through videos.

【Burrs crafted to help world champions win, optimized for pour-over brewing】
Wayne first points out that both the Femobook A4 and A4Z grinders are equipped with 48mm burrs. The key difference is that the A4Z uses the patented 1Zpresso ZP6 burr set, which was used by a World Brewers Cup Champion (WBrC) to win the title[1].
In addition, Wayne mentions that the A4Z adopts a design with independent grinding and drive cores. This structure results in more stable grinding and higher precision.
He believes this design improves the stability and flavor definition of pour-over coffee and expresses that he likes this electric grinder very much.

【Wayne Shih’s Review: Outstanding Grind Performance, The Top Choice for Pour-Over Brewing in His Studio】
Wayne thinks that the A4Z brings out clarity and bright acidity in pour-over coffee. The coffee bed after brewing is clean and even. Overall grind performance is excellent and very close to the flavor style he personally prefers.
Although some users may have different opinions about the product's exterior design, Wayne mentions he personally likes the A4Z’s overall structure and design.
In particular, the high grinding precision is the main reason why he consistently recommends this grinder. He even points out that the A4Z is his top choice for an electric grinder in his studio.
Wayne also notes that the A4Z continues the core features of the ZP6 and is especially suitable for users who want to improve their pour-over flavor.
For those who want to brew both pour-over and espresso, he recommends choosing the Femobook A68 or A5, which are better suited for a wider range of brewing needs.
Finally, Wayne kindly suggests that if users live in northern Taiwan and are interested in the A4Z electric grinder, users can visit Femobook’s direct retail store in New Taipei City to test it out before making a purchase decision[1].
