Gong Fu

by Lance Hedrick Hario Switch 02

Lance Hedrick's gongfu-tea-inspired Hario Switch recipe: three sequential closed-valve immersions with fresh water each time, a 75°C "Samo bloom" to preserve volatiles, and a spoon-pour technique that lets the coffee bed do the filtering. Designed to be forgiving across grinders and pours.

    Bloom

    Close the valve. Pour 50g of 75°C water into the empty Switch. Add 15g of coffee on top. Use the back of a spoon to push the grounds down into the water, ensuring full saturation with no clumps.

    Open the valve. Let the bloom water drain completely, then close the valve again.

    Pour

    Pour 100g of 90°C water onto the back of a spoon held just above the bed — the water rolls off without disturbing the grounds. Then gently excavate with the back of the spoon to encourage water into the bed.

    Open the valve for the final drawdown. Stir the cup before serving.

Notes

This recipe uses everything the Switch offers — closed-valve immersion, fresh water on every steep, and the bed itself as the primary filter. Three immersions push extraction higher than a French press while the bed-as-filter delivers cup clarity. Reverse bloom: pour the bloom water into the empty Switch first, then add the grounds on top. Pouring directly over grounds discharges fines into the paper, slowing drawdown and clogging the filter. Samo bloom (75°C): a cold bloom preserves volatile aromatics — same science as the frozen-ball method. Optional — works fine with all-90°C water. Spoon technique: for every main pour, pour onto the back of a spoon held just above the bed. The water rolls off the spoon and builds the column without disturbing the bed. After each pour, gently excavate with the back of the spoon to encourage water into the grounds. Steep timing is flexible — 1:00 to 1:30 per immersion. Immersion is hard to over-extract, so don't sweat exact times. This recipe scales from 15g to 22g doses. Above that, add a fourth pour. Grind is flexible — finer for more body, coarser for more clarity. Always stir the cup before serving — the brew comes out in concentration gradients.
