Hario Technica Siphon (5-cup)

Vapour pressure pushes water up into the grounds, then a vacuum pulls the brew back down through a cloth filter. Full immersion at a genuinely high, stable temperature. Also the best-looking thing you can do with coffee.

Roast	Grind	Coffee	Water	Time
light	medium	8 g	120 ml	2:30
medium	medium	8 g	120 ml	2:20
dark	medium-coarse	7.5 g	120 ml	2:00

Per 120 ml cup. Makes 3–5 at a time.

What goes wrong

Storing the cloth filter dry (goes rancid, taints every brew), an off-centre or slack filter (grounds bypass into the lower chamber, muddy), adding coffee before the water has fully risen (uneven wetting, weak), stirring hard during the steep (over-extraction at near-boiling temperature)

Care schedule

1 task for this machine.

Clean and store the cloth filter

Weekly

A siphon cloth holds oil and dries out hard. A dried filter brews slower and tastes of the last four brews at once, and one that has been left dry even once never fully recovers.

What you need

A small pan for boiling. Water only, no soap. A sealed container for the fridge.

What goes wrong

Washing it with soap. Air-drying the cloth between uses, which is exactly what ruins it. Storing it in water at room temperature, which grows mould in days. Persevering with a filter that has gone grey and slow instead of replacing it.

The procedure

Rinse the cloth in hot water immediately after brewing and squeeze the grounds out, without soap. Cloth holds detergent and gives it straight back to the coffee.
