How To Use This Tool

A dose calculator helps you match coffee weight to cup size, brew method, and preferred strength so you can avoid both weak brews and wasteful over-dosing.

Estimate dose quickly for single cups or larger batches.
Adjust for method because immersion and filter brewing behave differently.
Use custom cup sizes when your mug is nowhere near a standard serving.
  1. 1

    Choose cups, method, and strength

    Those three variables define the recommended starting dose.

  2. 2

    Use a standard or custom cup size

    If your brewer or mug is unusual, enter a custom volume so the recommendation stays accurate.

  3. 3

    Treat the result as a dial-in baseline

    From there, adjust slightly by taste rather than guessing a brand new recipe each time.

Common Questions

Click a question to expand the answer.

Is more coffee always the best fix for weak coffee?

Not always. Weak coffee can also come from grind size, short contact time, or poor extraction. A higher dose is only one lever.

How do cup size and brew strength interact?

Larger cups need more water, and stronger preferences need more coffee relative to that water. Both change the final dose recommendation.

Should I change dose for espresso and filter coffee the same way?

No. Espresso recipes are tighter and more sensitive to basket size, while filter doses scale more directly with beverage volume and target strength.

When should I use a custom cup size instead of presets?

Use a custom value when your mug, brewer, or travel tumbler is noticeably different from common serving sizes so the result reflects your actual volume.
