# Water Chemistry

## Getting Started

{% hint style="info" %}
Start by setting up a water profile for your local city water.

{% endhint %}

Then choose the source water you setup and a target water for the beer style you're making.  If you saved your recipe, added fermentables and salts or acids in Other Ingredients then you will see a predicted mash pH in the upper left hand corner.
