Introducing the latest iteration of the Pietro M-Modal Pro Brewing Burrs. Now in uncoated stainless steel for faster seasoning and exceptional clarity from your very first grind.
Designed in collaboration with Lance Hedrick and crafted by Fiorenzato's 80+ years of Italian grinding expertise, these 58mm flat burrs are purpose built for filter coffee perfection.
What's New: Stainless Steel, Minimal Seasoning
Unlike the previous Dark-T coated version, these updated M-Modal burrs feature a pure stainless steel construction. The result? Dramatically reduced seasoning time. Start enjoying clean, sweet, and aromatic cups without grinding through kilograms of coffee first. Ready to perform straight out of the box.
Why M-Modal Geometry Matters
The M-Modal burr design produces a tight unimodal particle distribution, significantly reducing fines that cause over extraction and muddiness. What you get is exceptional cup clarity, pronounced aromatics, and the true character of your beans. Exactly what pour-over and filter methods are meant to showcase.
