Calibrate with a coin or ruler for real-world micron accuracy. FOUR GRIND PROFILES Dial in for any brew method with built-in target ranges: - Espresso: 170-300ξm - Filter/Pour-Over: 400-800ξm - French Press: 750-1000ξm - Cold Brew: 800-1200ξm TASTE-TO-GRIND RECOMMENDATIONS Log how your coffee tastes — sour, bitter, balanced, weak — and GrindLab connects your flavor feedback to your grind data.

Log your beans (roaster, origin, roast level, freshness), brew parameters (dose, yield, temperature, time), and tasting notes with star ratings. Search and filter your history to spot trends and refine your process over time. COMPARE & IMPROVE Save analyses and compare them side by side. Overlay distribution charts, view delta metrics, and set a baseline to track how grinder adjustments affect consistency.
