Best Brew Water Temperature for Coffee

For most pour-over brewing, the practical working range is 90–96°C / 194–205°F. The goal is not memorizing one perfect number, but knowing when to go higher or lower.

Core Principle

Higher temperature: extracts faster, usually pulling more sweetness and bitterness
Lower temperature: extracts more slowly, often leaving more acidity and lightness

Suggested Range by Roast Level

Light roast: 92–96°C
Medium-light roast: 91–94°C
Medium roast: 90–93°C
Dark roast: 88–91°C

When to Raise Temperature

The cup tastes too sour
The body feels too thin
Aroma seems closed
The coffee is very fresh, dense, or lightly roasted

When to Lower Temperature

Bitterness is too strong
Roast notes dominate too much
The finish feels dry or harsh
You're using dark roast or espresso-style blends

Common Beginner Misunderstandings

Boiling water is not always best: it can be too aggressive for darker roasts
Lower is not automatically smoother: it can also make coffee thin and sour

Easy Starting Points

If you are unsure where to begin:

Light roast: 93°C
Medium roast: 91°C
Dark roast: 89°C

Then adjust by only 1–2°C at a time so you can actually taste the difference.
