Electric Single-Dose Performance for Exacting Brews
Quiet yet powerful, with near-zero retention and precision grind control—built for clean, flavourful pour-overs.
The Femobook A4Z is a precision-engineered electric grinder designed to elevate manual brewing with consistent, clean results. Crafted from CNC-machined aluminum alloy and powered by a quiet low-RPM motor, the A4Z preserves the subtle aromatic compounds essential to high-quality pour-over coffee.
Its 48 mm conical burr set—adapted from the acclaimed ZP6 design—offers excellent grind uniformity across a wide range of pour-over settings. The stepless adjustment dial allows for precise tuning, while the magnetic assembly system enables tool-free disassembly and effortless cleaning. With near-zero retention and a detachable battery capable of up to 110 brews per charge, the A4Z balances performance and practicality without compromise.
Designed for daily use and demanding brew (competition & research) standards, the A4Z offers consistent, single-dose grinding with minimal retention and no need for recalibration. While not intended for espresso, it excels in pour-over, AeroPress, and drip methods where grind precision and flavour clarity are paramount.

Effortless Grinding Without Compromise
Femobook is a young and ambitious company from Taiwan, founded in 2022, that’s redefining what it means to grind coffee at home. Specialising in electric coffee grinders, Femobook focuses on creating tools that cater specifically to specialty coffee lovers—those who care deeply about flavour, consistency, and ease of use.
Born from the Specialty Coffee Movement
With the global rise of specialty coffee, both the quality of beans and the complexity of processing methods have evolved rapidly. Femobook was founded in response to this shift, recognising that coffee equipment must advance in step with the beans themselves. Their grinders are designed to help users fully experience the unique flavours that specialty coffee offers—making high-quality brewing more accessible to more people.
Solving the Problems Most Grinders Ignore
Femobook sets itself apart by addressing the everyday frustrations of both hand grinders and conventional electric grinders. Many coffee enthusiasts face issues like:
- Inconsistent grind sizes
- Tiring and slow manual grinding
- Difficult cleaning and maintenance
- Inflexible grind settings that don’t meet espresso standards
Femobook's products are built specifically to overcome these challenges, with an emphasis on convenience, precision, and user experience.
Smart, Thoughtful Design – Down to the Details
Every detail in a Femobook grinder reflects thoughtful engineering. Key features include:
- Magnetic quick-release systems for effortless disassembly and cleaning
- Stable motor design and balanced weight distribution for consistent grinding
- Intuitive controls and fine-tuning capability, especially for espresso lovers
Their grinders are made not just to perform well, but to make the daily coffee ritual smoother, faster, and more enjoyable.
What’s in a Name?
As a Taiwanese brand, Femobook has infused its name with creativity and cultural flair. The name “Femobook” (Fe-mo-boo-k) is a playful phonetic pun in Mandarin, and it can be interpreted in several meaningful—and coffee-related—ways:
飛磨不可 – Flying grind
"We believe that each cup of coffee is a journey beyond the ordinary."
啡磨不可 – Grinding perfectly
"Every cup of coffee represents a wonderful moment."
非磨不可 – You must grind it
"An essential coffee grinder that you can’t live without!"
Each interpretation reflects Femobook’s philosophy: coffee is more than just a drink—it’s a daily ritual, a moment of joy, and a way to connect.
