Pietro Grinders - Flat Burr Coffee Hand Grinder

The Pietro Grinder is a high-performance manual grinder engineered for precision, consistency, and ergonomic excellence. Designed and manufactured in Italy, this grinder stands out with its vertical flat burr design, delivering uniform particle size for both espresso and filter brewing.

At the heart of the Pietro is a 58mm flat burr set, available in either the  Multipurpose or Pro Brewing configurations. These burrs are made from high-grade M340 steel and are vertically mounted, a design that promotes even feed and reduces retention, a unique feature rarely seen in manual coffee grinders. This vertical burr geometry enhances grind consistency and clarity in the cup, especially for complex single origin coffee brewing.

The grinder’s retractable handle offers smooth operation and folds neatly for compact storage. Its anti-slip rubberised base ensures stability during grinding, whether you're dosing for a delicate pour-over or a high-pressure espresso shot.

All components in contact with coffee are made from certified food-safe materials, including an internal anodised aluminium chamber and POM components for reduced static and minimal retention. Every material has been selected not only for performance, but for longevity and ease of cleaning. As well as this when the pietro is closed the entire unit is air tight to prevent oxidation and possible water damage to the internals.

Designed with long-term durability in mind, the Pietro features tool-free disassembly, and precision machined internal parts that ensure years of reliable performance every time you grind your coffee.

Made entirely in Italy, Pietro Grinders reflect a commitment to craftsmanship and functional design. If you demand quality, precision, and aesthetics in your brewing workflow, this is the grinder for you.

Why Grind Coffee Fresh?

When whole beans of coffee are ground their surface are dramatically increases, and with more surface comes exposure to air that quickly starts to turn your coffee stale.

Avoid this by grinding your coffee as soon as you're ready to brew.

    Flat Burrs

    Flat burrs use two flat, parallel discs with sharp, ridged edges to grind coffee beans. One disc remains stationary while the other rotates, and beans are crushed between them. This design produces a highly uniform grind size, which is ideal for espresso and other brewing methods that require precision. Flat burrs are known for emphasising clarity and brightness in the cup, often bringing out more defined flavours.

  • Cone Burrs

    Conical burrs consist of a cone shaped inner burr that fits inside a hollow, ring shaped outer burr. Beans are fed through the top and ground vertically, resulting in a more natural and efficient workflow that tends to generate less heat. This type of burr is favoured for manual coffee grinder and home use due to its lower power requirements and quieter operation.

What Grind Size To Use?

Different brew methods require a different grind size, pour over for example relies on gravity to pull the hot water through the bed of coffee grounds and filter into the bottom.

Espresso on the other hand have large amounts of pressure pushing the water through the puck of coffee and a finer grind size is required to build resistance.
