Coffee to water ratio chart

Starting ratios you can repeat, with the espresso row measured differently on purpose.

Each bar is the water that meets one gram of coffee. Espresso is drawn on beverage ratio, which is why it is so much shorter than the filter methods.

Why espresso is measured differently

Brew ratio here means brew-water mass divided by dry-coffee mass. Espresso beverage ratio instead uses beverage mass divided by dry dose. the Specialty Coffee Association on brew and beverage ratios keeps the two apart, and mixing them is the most common arithmetic error in coffee.

These are starting points

Every figure in this table is a CupTune-authored starting point, not a standard. Take the row, brew it once, record it in the journal and change one variable. The ratio guide explains what the number can and cannot control.

Reading the ratio chart

What ratio should I use for pour over?

CupTune's authored starting point is 1:16, so 20 g of coffee to 320 g of water. It is a place to begin a comparison rather than a correct value.

How much coffee per litre of water?

About 60 g per litre at roughly 1:16.7, which is the usual batch-drip starting point. The table scales every method to whatever dose you enter.

Why is the espresso row so different?

Because it is measured differently. Espresso quotes beverage mass out divided by dose in, while every other row quotes brew water against dose.

Are these ratios a standard?

No. Every figure in the table is a CupTune-authored starting point. They are chosen to be repeatable and adjustable, not to be authoritative.
