Fuji R-220 Flat Burr Grinder for Single Origin Brewing

If you’ve ever pulled a shot or poured a pour-over only to find your coffee tastes overly bitter or astringent, inconsistent extraction might be the culprit—and often, it starts with uneven grind size and too many fine particles. For specialty coffee professionals and serious enthusiasts, choosing the right grinder is just as important as selecting the beans themselves.

The Fuji R-220 is a 200g-capacity flat burr grinder widely used in national coffee competitions for its ability to produce uniform grinds with notably fewer fines. It runs on 100V power, has a 100W motor, and processes up to 250g of coffee per minute.

What Is the Fuji R-220 Grinder?

The Fuji R-220 is a compact, single-origin-focused flat burr grinder designed primarily for brewing applications rather than espresso. It measures 165×245×360mm, weighs 5kg, and comes in black and yellow color options. Though sometimes referred to as a 'ghost tooth' grinder due to its burr design, it actually uses a cast iron alloy flat burr set.

Key Technical Specifications

The R-220 is built for precision and consistency. Its key specs include:

• Weight: 5kg
• Bowl capacity: 200g

These specifications make it suitable for high-volume single-origin brewing where grind uniformity and minimal fines are critical.

Why the Cast Iron Alloy Burr Matters

The grinder’s burrs are made from a cast iron alloy, not steel, and are engineered to slice rather than crush the coffee beans. This shearing action helps reduce the production of fine particles—commonly known as fines—that can lead to over-extraction and bitterness. By tearing the beans more cleanly, the R-220 contributes to a more even extraction profile, especially beneficial for pour-over, French press, and other full-immersion brewing methods.

Who Uses the Fuji R-220?

This model is known for being a go-to grinder in national coffee competitions, particularly for single-origin brews. Its consistent grind quality and manageable capacity make it a reliable tool for baristas focusing on showcasing the nuances of single-origin beans without the complications of fine-tuning an espresso grind.

Frequently Asked Questions

Is the Fuji R-220 suitable for espresso grinding?

No, the Fuji R-220 is designed primarily for single-origin brewing methods like pour-over, French press, and drip. It is not optimized for espresso, which requires a finer and more precise grind size that this model isn’t calibrated to produce consistently.

What does “ghost tooth” refer to in this grinder?

The term “ghost tooth” is a colloquial nickname for the R-220’s burr design. It refers to the unique cutting pattern of the flat burrs, which some users associate with a ghost-like or less aggressive grinding action, though the grinder actually uses standard flat burrs made from cast iron alloy.

Why does the R-220 produce fewer fines compared to other grinders?

The R-220’s cast iron alloy flat burrs are designed to slice through coffee beans rather than crush them. This shearing action minimizes the creation of fine particles, resulting in a more uniform grind size with fewer micro-fines that can lead to bitterness or channeling during brewing.

Can I use the Fuji R-220 with 220V power?

No, the Fuji R-220 is built to run on 100V power, which is standard in Japan. It is not compatible with 220V outlets without a step-down transformer, so check your voltage requirements before purchasing.

How much coffee can the R-220 grind at once?

The R-220 has a 200g bean hopper capacity and can process up to 250g of coffee per minute. This makes it suitable for small-batch brewing sessions but not for high-volume commercial use.
