The filter coffee recipe series is designed for this: taste your cup, then move up the series for more extraction or down for less. It works the same whether you brew with a V60, a Switch, a Kalita, an Origami or a cloth drip pot. Don’t hesitate to experiment with another recipe based on your taste test results—finding what tastes best for you is worth it!

Don’t get hung up on the details. A Switch, a V60, a Kalita, an Origami, a Deep 27 or a cloth drip pot: the settings are the same. If you don’t have the right grinder, or you don’t know what that grind size even means, it doesn’t matter.
Providing you are changing the dose, the ratio, the bits you can, you will be changing the TASTE, and that is what matters. YOU are finding a RECIPE that tastes better than the last recipe you tried.
Pre-heat. Rinse the paper filter with hot water to wash out the paper taste and heat the brewer, then tip the rinse water out of your cup or carafe. Using cloth? Rinse it, wring it out, and never let it dry out between brews; keep it in water in the fridge.
Get your single dose out of the freezer. If you are not single-dosing and freezing your coffee, read How to Store Coffee Beans – 9 tips. While at it, read Best Coffee Beans – Six Purchasing Tips.
Grind your frozen coffee; do not defrost it.
Put a drip stand over your cup or carafe, put the cup on the scales, sit the brewer on the stand, and tare. You are weighing the coffee you actually get, not the water you pour. On a Switch or a Clever, close the valve first. If you use Cafec papers, the settings above show which one suits this roast.
Bloom. Pour straight from the kettle, without the Melodrip, about three times the dose of water. Stir with a wet WDT stick so every ground is wet and no dry clumps are left, then wait for the bloom time shown above. Just like pre-infusion in espresso, this is where most of the extraction happens, and fresh coffee needs time to degas. You are NOT in a hurry.
I recommend using a Melodrip, pouring in multiple small batches, and keeping the water level just above the coffee bed. Swap out the cup when it reaches the yield you chose. The last of the drawdown is the most bitter part, so you lose nothing.
Switch or Clever: pour through the Melodrip with the valve closed, then open it and aim to reach the yield around the brew time. V60, Kalita, Origami, Deep 27 or cloth: aim to reach the yield around the brew time. Don’t chase it to the second.
Now, the most crucial step. Swirl the coffee, dip a teaspoon in and taste. Is the coffee sour? If so, next time you make this coffee, extract more using the recipe indicated by the button above.
If the coffee isn’t sour, ask yourself whether it is very bitter. Bitterness is harder to judge because all coffee is bitter to some extent. However, you can reduce bitterness by extracting less. Go too far, and it will turn sour. You are looking for the calm spot in between. If you need to reduce bitterness next time you make this coffee, extract less by using the recipe indicated by the button above.
Making a big brew? Past about 500 ml the bed gets deeper, drains slower and extracts more, so expect to step towards Extract less, or grind a little coarser.

Ecuador has become one of the most exciting origins in specialty coffee, and Sidra is the variety that put it there. This is a washed single-variety lot from one producer, so it shows Sidra at its clearest.
Fausto Romo grows coffee at La Carolina in Pichincha. Passenger released this washed lot alongside a honey-processed one from the same 2025 harvest, which makes a good side-by-side comparison of process.
Pichincha is the highland province around Quito in northern Ecuador. Its farms sit on the slopes of the Andes, where cool nights and high altitude slow cherry ripening and build sweetness.
ORIGIN: PICHINCHA, ECUADOR
FARM: LA CAROLINA
PRODUCER: FAUSTO ROMO
VARIETY: SIDRA
PROCESS: WASHED
HARVEST: 2025
Sidra is a rare variety now closely tied to Ecuador. Its origins are debated, but it is prized for florals, tea-like elegance and layered sweetness, and it has become a favourite on the competition stage.
Washed coffees have the fruit removed before drying, so the cup is shaped by the variety and the farm rather than by fermentation. It is the best way to taste what Sidra itself brings.
Passenger Coffee roasts in Lancaster, Pennsylvania, in the US. This lot is sold in sizes from 125 g up to 5 lb.

I have a dream: that this might raise the standard of coffee-making globally, reduce dialling in waste, time, and frustration, and encourage people to explore more varieties and pay more attention to the producers. You might even be prepared to pay more for better coffee if it pleases you, returning more money to growers.
