The Technology: 15-Stage Sequential Sieve Array
- Physical Scanning: The sample passes through our proprietary, sequential 15-stage sieve array to rigorously categorize particle size distribution.
- Isolation of Variables (Control Sample): We supply certified organic Arabica control beans from Peru. Standardized roasting protocols eliminate thermophysical density and moisture fluctuations. Any granulometric variance reflects strictly on the mechanical tolerances of the grinder.
- Boulder Detection (>2000 μm): Identifies coarse particles exceeding 2000 microns. These are direct drivers of hydraulic channeling, localized under-extraction, and astringent sourness.
- Fines Detection (<180 μm): Identifies micro-dust particles below 180 microns. These obstruct hydrodynamic flow and produce excessive, aggressive bitterness.
- Algorithm & IP: Harvested raw sieve data is processed through our closed-source analytical software. High-resolution intermediate metrics are disclosed exclusively within the client metrology report.
The Deliverable: Computerized Metrology Report (PDF)
- Modal Peak: Mathematical identification of the primary grinding distribution peak.
- The Sweet Spot: Verification of optimal particle concentration, targeting >75% within the designated extraction window.
- Burr Condition: Pinpointing mechanical tolerances indicative of cutting-edge wear, runout, or loss of geometric alignment.
- Multi-State Profiling: Evaluate up to 5 grind settings within a single testing kit, with dedicated profiling curves for absolute comparability.
