Quick answerThe ideal water temperature for brewing hot coffee is 90-96°C (195-205°F). Without a thermometer, let boiling water rest for about 30 seconds. Darker roasts like a medium-dark Yemeni roast taste best at the lower end (90-93°C) to avoid bitterness.
Why temperature matters
Hotter water extracts flavor faster. Too hot and coffee turns bitter; too cool and it tastes sour and thin.
Guidelines
- Light roasts: 94-96°C
- Medium and medium-dark: 90-94°C
- Dark roasts: 88-91°C
- Cold brew: cold or room temperature, 12-18 hours
At high altitude
Water boils below 100°C at altitude, so you may brew right off the boil.
