Know before you buy
These burrs are designed as a direct replacement for the Option-O Lagom P64 and the Niche Zero. They are compatible with any grinder that accepts standard 64mm flat burrs.
The Mizen 64om burrs feature a unique flat geometry designed to increase particle uniformity compared to the conical burrs typically found in the Niche Zero. This shift generally results in higher flavor clarity and a more modern, nuanced espresso profile.
Yes, moving from conical to flat burrs often requires a finer grind setting and may change your puck preparation routine. You should expect to dial in your coffee again once the burrs are installed.
Like most precision-machined stainless steel burrs, the Mizen 64om will perform at its peak after a seasoning period. You may notice the flavor profile stabilize and improve after grinding a few pounds of coffee.
The Mizen 64om geometry is engineered to highlight the acidity and complex flavor notes found in light-to-medium roasts. While they can handle darker roasts, they truly excel at bringing out the clarity in modern, specialty-grade beans.
