  1. 1

    Select your brew method from the dropdown.

  2. 2

    Select your roast level from the dropdown.

  3. 3

    The calculator outputs a recommended grind size setting on a scale from 1 (fine) to 7 (coarse).

((brew_method == 'espresso') ? 1 : (brew_method == 'moka') ? 2 : (brew_method == 'pour_over') ? 3 : (brew_method == 'french_press') ? 4 : 5) + ((roast_level == 'light') ? 0 : (roast_level == 'medium') ? 1 : 2)

常见问题

What does the grind size number mean?

It's a relative scale from 1 (very fine, like espresso) to 7 (very coarse, like cold brew). Adjust based on your grinder's settings.

Why does roast level affect grind size?

Darker roasts are more porous and extract faster, so they often need a slightly coarser grind to avoid over-extraction.

Is this calculator accurate for all grinders?

No, it's a starting point. Grinder calibration varies, so taste and adjust from the suggested setting.

公式

此计算器背后的数学公式，供您核对结果。

Base grind by method

Espresso=1, Moka=2, Pour Over=3, French Press=4, Cold Brew=5

Each brew method has a typical grind fineness range.

Roast adjustment

Light=0, Medium=+1, Dark=+2

Darker roasts shift the grind coarser.

实际应用场景

此计算在日常生活中的应用。

Brewing at home

Get a starting grind size when trying a new brew method.

Example: Switching from French press to pour over.

Dialing in a new grinder

Use the suggested setting as a baseline for calibration.

Example: First use of a new burr grinder.

Adjusting for roast

Fine-tune grind when changing roast levels.

Example: Moving from medium to dark roast beans.
