Office Coffee

Succeeding with your cup away from home

Home coffee is your territory. Office coffee is a race on an unknown track. Sometimes poor tap water, limited equipment, lack of time. But with the right strategies, you can drink very well even on the 14th floor of an office tower.

Office water

The source of 80% of coffee problems

Good water makes as much difference as the coffee itself. And it's often the most overlooked factor.


The ideal water for coffee contains between 75 and 175 ppm of total minerals. Too little: the water "steals" the coffee's aromas. Too much: it creates astringency and scale.

Simple solution: bottled water

Slightly mineralized water (Evian, Volvic, Laurentides) is ideal. Avoid very hard waters like Perrier or Contrex for coffee.

Advanced solution: Brita filter

A filtered pitcher reduces chlorine and softens the water. This is often enough to significantly improve office coffee.

Watch the temperature

The office kettle is often too hot (100°C). Let it rest for 30 seconds after boiling to reach the ideal 92-94°C.

The rules

5 rules for perfect office coffee

Simple, effective, immediate

Five habits that change everything.


1 — Bring your own beans

Office coffee is almost always old and poorly stored. Bring your own beans in a small airtight container. Even 15g for one cup makes all the difference.

2 — Grind just before

60 seconds of manual grinding. This small action doubles the perceived quality in the cup. The aroma released while grinding is already a pleasure in itself.

3 — Preheat your cup

A cold cup immediately lowers the coffee temperature by 5 to 8°C. Rinse your cup with hot water before brewing. The result stays hot longer.

4 — Never reheat

Microwaved coffee is wasted coffee. If you don't have time to drink your coffee hot, prepare it as a cold concentrate or accept room temperature.

5 — Clean your equipment

Rancid coffee residues spoil the oil and affect every following cup. Rinse with hot water after each use. Clean thoroughly once a week.
