The Complete Mosaic Coffee Co. Guide: Best Beans, Brewing, and Store Details
By Sarah Jenkins
Extracting the full dynamic range of single-origin beans requires attention to water chemistry and turbulence. High-density, high-altitude beans compact easily, making flow rate control mandatory. Artisan brewing methods like the cone pour-over reward patience and exact ratios.
Use this calibrated pouring sequence for light-to-medium single-origin offerings:
Start with a clean 1:16 brew ratio. Measure 20 grams of whole bean coffee ground to a medium-fine consistency, resembling kosher sea salt. Heat filtered water containing 70, 120 ppm total dissolved solids to 204°F (95.5°C). Rinse your paper filter with hot water to wash away residual wood pulp taste and preheat the brewing vessel.
Begin extraction with a 60-gram bloom poured over 10 seconds. Swirl gently to saturate the bed, then wait 40 seconds while trapped carbon dioxide escapes. Pour the second pulse up to 200 grams in slow, concentric circles. Conclude with a final stream reaching 320 grams total weight by the 1:45 mark. Allow the bed to draw down completely. The slurry should finish flat, yielding a crystal-clear cup around 3:00 to 3:15.
