Brewing filter coffee with KinGrinder K7

Coffee brewing for a software engineer quickly turns into an optimization problem: water temperature, grind size, coffee-to-water ratio, and pour timing all directly shape the final cup.

My daily setup:

  • Dripper: glass cone dripper compatible with V60 01 paper filters
  • Grinder: KinGrinder K7
  • Scales with timer

Grind size is the most critical variable. The KinGrinder K7 offers 15-micron adjustment per click (100 clicks per full turn).

Since many community recipes use Comandante C40 clicks as a baseline, I use a simple formula: KinGrinder K7 clicks = Comandante clicks * 4

My standard 250 ml recipe:

  • Dose: 15 g of coffee (1:16.7 ratio)
  • Grind: 95-100 clicks on K7 for medium-light roast
  • Water: 250 g at ~93C

Pour steps:

  • 0:00 - 45 g water for blooming, wait 40 seconds.
  • 0:40 - pour in gentle circles up to 150 g.
  • 1:15 - pour in spirals up to 250 g.
  • 1:25 - gentle swirl to level the coffee bed and let it draw down.

Total brew time is around 2:15 to 2:45. Gives a clean cup with bright sweetness and no unpleasant bitterness.
