About This Free Online Cold Brew Calculator

Our free cold brew calculator works out the coffee weight for a cold brew batch. Enter the water volume and the water-to-coffee ratio, and the tool returns the ground coffee weight in grams, the expected yield after steeping and straining, and whether the result is a concentrate (typically 1:4 to 1:6) that you dilute before serving or a ready-to-drink brew (1:7 and up). Everything runs in your browser — instant, private, no signup.

  4. Dilute the concentrate to taste before serving.

Frequently Asked Questions About Cold Brew Calculator

What ratio should I use for cold brew?

For a concentrate you will dilute later, use 1:4 to 1:6. For ready-to-drink cold brew served straight, use 1:7 to 1:10. The calculator flags which style your ratio produces.

How much cold brew will I get?

After the grounds absorb water and you strain them out, expect a yield of roughly the water minus about twice the coffee weight. The calculator estimates this for you from the inputs.

How long should I steep cold brew?

Most recipes steep 12 to 24 hours in the fridge or at room temperature. Steeping longer extracts more and tastes stronger, so adjust the ratio or the steep time to hit your preferred strength.

Can I make hot coffee from cold brew concentrate?

Yes. Dilute the concentrate with hot water or milk, usually one part concentrate to one or two parts water, then adjust to taste. The calculator tells you when your ratio makes a concentrate.

Is this cold brew calculator free?

Yes, completely free with no signup. All maths runs in your browser — nothing is uploaded or tracked.
