    Pour

    Heat 400g of water in lower chamber to 99°C. Seal upper chamber. Wait for water to rise. Temperature in upper chamber stabilizes around 94°C.

    Swirl

    Lower heat to two-thirds. Add 24g of extra-fine coffee. Stir vigorously for 15 seconds, then give one rotation.

    Wait

    Rest for 20 seconds. At 0:35, remove from heat immediately. Give a gentle circular stir to induce drawdown.

  4. 1:30 04
    Wait

    Vacuum pulls brewed coffee through the filter into the lower chamber. Inspect the coffee bed — it should be flat and uniform.

    Done

    Drawdown complete. The result is an intense, full-bodied cup with very high extraction yield.

Notes

Source: Jonathan Gagne, Coffee ad Astra (coffeeadastra.com). Grind as fine as Turkish coffee — the grounds should feel like flour and form clumps. This method achieves very high extraction (23-24%) in under a minute of steep time. Requires precise temperature control and vigorous stirring.
