64OM Burrs: Truly Omnipurpose Grinding
The 64OM burrs were developed with a clear goal in mind: to create a versatile 64mm burr set that performs exceptionally well across a range of brewing methods, from espresso to pour-over styles like V60, Kalita, and Chemex. By refining the popular cast burr teeth design and applying innovative finishing techniques, we've crafted a burr set that delivers enhanced clarity, clean sweetness, and balanced body—allowing the unique characteristics of each coffee’s terroir and processing to shine through in every cup.

Why Mizen? A Symbol of Precision and Purpose
Mizen (pronounced "mai-zn") is the name of our product line dedicated to our in-house developed burrs, reflecting our philosophy and commitment to burr innovation. Inspired by the "Mizzenmast", a crucial sail on a ship that contributes to its balance and direction, Mizen represents the essential role burrs play in a grinder’s performance. As the saying goes, "grinder, grinder, grinder," and at the very core of every grinder are the burrs. We believe that exceptional coffee starts with exceptional burrs, which is why they’re at the heart of everything we design

FAQ's for Option-O Mizen 64mm
What Does the Cup Profile Taste Like?
For Espresso:
When used for espresso, the 64OM burrs bring out excellent flavour separation and heightened clarity in the cup. Expect a clean, sweet espresso with a medium to high body and satisfying mouthfeel, ideal for those who appreciate nuance and balance in their shots.
For Brewed Coffee:
When dialled in for coarser grind settings—such as for pour-over or immersion brews—the 64OM burrs produce a grind quality that supports a complex, juicy cup with pleasing texture and minimal astringency. While the particle size distribution is slightly broader than that of unimodal-style burrs, it remains notably tighter than conventional flat burrs—striking a balance that brings out both clarity and depth in your brew.
Who Are These Burrs Best Suited For?
If you're in search of a truly all-purpose burr set for your LAGOM P64, enjoy modern, medium-light roasts, and equally value clarity, sweetness, and tactile mouthfeel, we’re confident the 64OM burrs will exceed your expectations—just as they have ours.
Which Brewing Methods Are They Suitable For?
The 64OM burrs are designed to perform across all major brewing methods, including:
- Espresso
- Pour-over (e.g. V60, Kalita, Chemex)
- Immersion brewing (e.g. French press, AeroPress)
- Moka pot
Their grind performance is optimised for versatility, offering excellent results regardless of your preferred method.
What Roast Levels Work Best?
The 64OM burrs are compatible with all roast levels, though they particularly shine with medium and lighter roasts. Their design brings out the vibrant, intricate flavour notes often found in modern roasting styles, without sacrificing sweetness or balance.
