# Coffee Ratios

##### Coffee and Espresso Ratios

Coffee and Espresso ratios calculator, for both Espresso and larger drinks.

### About:

**Coffee Ratios** is an app that aims to help you to easily calculate ratios either for espresso or larger drinks, that’s why the app has two modes **Coffee** mode and **Espresso** mode.

#### Sections:

##### Coffee In:

Drag the slider or click the buttons to change the value of the amount of coffee you’re putting in. Editing this value changes **Coffee Out/water needed**, using the current value of the **ratio**.

##### Coffee Out/Water Needed:

Using the slider or the buttons changes the value. By doing this, it will udpate the value of the **ratio**.

This section changes the name from **Coffee out** while on Espresso mode, to **Water needed** on Coffee mode.

##### Ratio:

Use the buttons to change the value. Changing the ratio changes the value of **Coffee Out**.

#### Notes:

- Changing
**Coffee In**at the current ratio generates a change in**Coffee Out**. - Changing
**Coffee Out/Water needed**generates a change in the ratio (if**Coffee In**stays the same). - Changing
**Ratio**will generate a change in the**Coffee Out/Water needed**(if**Coffee In**stays the same). - Locking up ratio (by closing the
**Lock**button) it will allow you to edit the**Coffe In**amount by changing the value of**Coffee Out**. - On Coffee mode, you can tap on the ratio text to switch between grams per liter (g/l) to ratio (1:N).”

### How to use:

#### Espresso.

Set the **coffee in** value to the amount of coffee your basket uses.

After doing so, you’ll have to a couple of options:

- You can set the expected size of your expresso by changing the coffee out value, this will update and tell you the ratio value.
- If you know the ratio you want, you can set that in the ratio section, either by using the plus/minus buttons, or the pre-defined ratio ones. By doing so, you’ll see the coffee out value changing. When brewing your coffee, if you stop your espresso machine when you hit that
**coffee out**value, will mean that you have reached the desired ratio.

#### Coffee.

If you know a recipe you can enter the values, let’s say 11grams for a 200ml cup of coffee.

Enter 11 as your **coffee in** value

Enter 200 as your **water needed** value

This will update the **ratio** value to be 55/L (or 1:18.2 if using ratio instead of grams per litter)

Now, le’ts say that you want that recipe but for a 300g cup. Here’s what you do:

Click on the lock button next to the **ratio** value.

Change the water needed to be 300.

By doing so, the app will update the required **coffee-in** value (16.5 in this example). Meaning that, for a 300g(or ml) cup, you’ll need 16.5 grams of coffee.
