V60 02 V60 by Doha Coffee

A Japanese-tradition hand-drip technique from Doha Coffee: a concentrated 1 · 3 · 9 build — bloom once, brew a strong center-poured concentrate, then dilute with a large bypass — for a clean, syrupy, sweet cup from medium and dark roasts.

Notes

Same 1 · 3 · 9 ratio at any dose: bloom once, brew to a concentrate, then dilute with a large bypass. Match the dripper to the dose — Hario 01 or Kalita 101 for small doses. Start the timer only once the bloom water is fully in. Keep the early pours gentle and centered, then grow the stream after 1:30 and finish with a stronger center pour — without flooding and collapsing the bed. Fresh, gassy coffee starts extracting later than 1:30; that is fine. Adjust the final bypass to taste — less bypass gives a stronger cup.
