Weigh 25g of coffee and grind on a medium-coarse setting to a coarseness of coarse sea salt. Set up the Kalita Wave, filter, and vessel on the scale. Heat 400g of water in the kettle to 208° Fahrenheit (just off boil).

Gently pour hot water into the center of the empty filter. Continue pouring in a spiral outwards to wet the entire filter. Be careful not to pour too hard as the filter can collapse. Empty the water from the vessel, place back onto the scale, and tare to zero.

Add the coffee to the Kalita Wave with the vessel on the scale, ensuring that you add 25g of ground coffee, and tare to zero.

Start the timer and add 50g of water to the bed of coffee quickly, in about 5 seconds, ensuring to saturate all the grounds. Let the coffee bloom for 25 seconds. As the gasses escape, the bed will breathe and expand!

When the timer reads :30, start pouring in the center and spiral out in concentric circles. It's okay to pour onto the filter walls if grounds are clinging to the paper. Continue pouring in concentric circles spiraling back in towards the center until the scale reads 150g. This should take about 30 seconds. Let the slurry drain for about 15 seconds.

If ...
- your brew finished after the time goal or tastes bitter, grind coarser
- your brew finished before your time goal or tastes sour, grind finer
- your brew finished in your time goal but is too concentrated/intense/strong, pour more water
- your brew finished in your time goal but is too weak/watery, pour less water
- your brew bed is not flat (peaks and valleys), make sure your water stream is consistent as you pour in concentric circles
