Understanding Brew Ratios

A brew ratio is simply the weight of coffee going in compared to the weight of liquid coming out. Write it as 1 : N, where N is the yield divided by the dose.

An 18g dose pulling 36g of espresso is a 1 : 2 ratio. That's the classic starting point for a balanced shot.

The espresso range

| Ratio | Name | Tastes like | |---|---|---| | 1 : 1 – 1 : 1.5 | Ristretto | Syrupy, intense, lower extraction | | 1 : 2 | Normale | Balanced and sweet | | 1 : 3+ | Lungo | Lighter body, higher extraction |

Pour over lives in a different world entirely — typically 1 : 15 to 1 : 17 — but the idea is the same: more water relative to coffee means a lighter, more extracted cup.

Using ratio to fix a shot

Ratio is the first dial to reach for:

• Too harsh or hollow? Pull a little shorter — toward 1 : 1.8.
• Thin or weak? Stop the shot earlier for more concentration, or grind finer.
• Sour and underdeveloped? Often grind, not ratio — but a slightly longer ratio can help fill it out.

The trick is to hold dose constant and change only the yield. That keeps the ratio honest and the comparison clean — exactly the kind of single-variable change a journal is built to track.
