Espresso Brew Ratio Calculator
This free espresso brew ratio calculator helps you estimate espresso yield from dose, brew ratio, and shot style so you can dial in more consistent home espresso.

Calculate Dose, Yield, and Brew Ratio
Enter your coffee dose and choose a brew ratio. The calculator estimates your espresso yield and gives a practical shot guidance note.
Recommended shot target
36.0g espresso yield
Dose: 18.0g coffee
Brew ratio: 1:2.0
Shot style: Standard espresso
A 1:2 ratio is a common starting point for home espresso. Adjust grind, yield, and time by taste.
How to Use the Espresso Brew Ratio Calculator
Use the Espresso Brew Ratio Calculator by entering your coffee dose in grams and selecting a target brew ratio. The calculator multiplies your dose by the ratio to estimate your espresso yield.
For example, an 18g dose at a 1:2 brew ratio gives a target yield of about 36g of espresso. This is a common starting point for home espresso, but taste should guide your final adjustment.
If your espresso tastes sour, try the Grind Size Calculator to check whether your grind should be finer. If you are brewing drip, pour-over, French press, AeroPress, or cold brew, use the Coffee Ratio Calculator instead.
Espresso Brew Ratio Chart
Espresso ratios compare dry coffee dose to liquid espresso yield by weight. These are practical starting ranges, not fixed rules.
| Shot Style | Common Ratio | Example with 18g Dose |
| Ristretto | 1:1.5 | About 27g yield |
| Standard Espresso | 1:2 | About 36g yield |
| Longer Espresso | 1:2.5 | About 45g yield |
| Lungo-style | 1:3 | About 54g yield |

A brew ratio helps you set the target. Your grinder, machine, puck prep, and shot time determine whether the espresso actually tastes balanced.
What is an espresso brew ratio calculator?
An espresso brew ratio calculator is a coffee tool that estimates espresso yield based on your dry coffee dose and target brew ratio. For example, an 18g dose at a 1:2 ratio gives about 36g of espresso yield.
What is a good espresso brew ratio for beginners?
A 1:2 espresso brew ratio is a good starting point for beginners. That means 18g of ground coffee would produce about 36g of espresso in the cup.
What does 1:2 mean in espresso?
A 1:2 espresso ratio means the espresso yield is twice the weight of the dry coffee dose. For example, 18g of coffee in and 36g of espresso out is a 1:2 ratio.
Should I change espresso ratio or grind size first?
Change grind size first when your shot time or flow is clearly off. Change brew ratio when the shot is close but needs a taste adjustment, such as slightly more sweetness, body, or clarity.
Why does my espresso taste sour?
Sour espresso usually means under-extraction. Try grinding finer, increasing the yield slightly, improving puck prep, or allowing the shot to run a little longer.
Why does my espresso taste bitter?
Bitter espresso usually means over-extraction. Try grinding slightly coarser, reducing the yield, shortening the shot, or checking that your water temperature is not too high.
