Measure 15g of freshly roast beans and grind them to a medium size, the same as you'd use for pour-over coffee. We use a 1:16 coffee to water ratio (so, 240ml of water). However, if this produces a coffee that's too weak for your tastes, try using 20g of coffee and 240ml of water (a 1:12 ratio).
Place a paper filter in the cone and rinse it using hot water. Let the water drain into your cup so that it warms up, then pour away the water.
Ensure the switch is flicked up so the ball is blocking the bottom of the cone filter. Next, pour your freshly ground coffee into your paper filter.
Pour 240ml of 200F (93C) water over the coffee grounds. Gently stir the water so it mixes in with the grounds, leaving them completely saturated.
Set a timer for four minutes. The Hario Switch manual recommends a two-minute immersion time. However, its recipe uses a higher dosage, which allows for a shorter brewing time. Because we're using a 1:16 coffee to water ratio, we opt for a four-minute immersion time to extract the necessary flavor and complexity.
After four minutes, gently swirl the brewer to form a flat coffee bed. Then, flip the switch, and the coffee will slowly draw down into your cup. It takes around 45 seconds for this process to complete.
Now it's time to enjoy your coffee, but take care when taking away the dripper beforehand. The glass part will be hot, and there isn't a handle, so hold the silicone rubber base instead.
