The Eau Profile Tool (Tools Ribbon) can be used to match specific brewing Eau profiles from around the world. This is important, particularly for all grain brewers who would like to match a particular Eau profile during the mash to achieve a certain flavor or Amertume profile.
New Feature: BeerSmith now includes a Calculate Best Additions button that automatically finds the best Eau additions to match your base and target Eau profile. It does this using a "best fit" linear programming model.

How to Use the Outil Profils d'Eau
| o | Select the Eau Profile tool from the Tools menu or ribbon. |
| o | Select the Eau you are targeting using the Target Profile button |
| o | Select the Eau you are starting with, such as your local Eau profile using the Base Profile button and enter the volume of Eau used |
| o | Click on the Calculate Best Additions button to find the best additions possible to match your base profile to your Eau profile |
| o | Optionally, you can also use the Dilute With button to add a volume of Eau to dilute the base Eau profile. This is useful, for example, if you want to use distilled or bottled Eau to reduce the ion content of your base Eau to match a given profile. |
| o | If you click on Save Totals you can save the total ions shown as a new Eau profile. |
| o | If you click on Save Additions to Target you can save the Eau additions to the target Eau profile so they will be used in a recipe if you add that target Eau profile to a recipe in the future. |
Understanding The Tool
| o | The tool is displayed as a table. The columns in the table represent the various ions present in the Eau profile (Ca for Calcium, Mg for Magnesium, Na for Sodium, SO4 for Sulfate, Cl for Chloride and HCO3 for bicarbonate). |
| o | The rows from top to bottom show the base Eau profile, effect of various Eau additions (such as Gypsum and Chalk), the Eau you are duliting with (if applicable), and the totals for your base Eau, plus additions and the dilution. |
| o | The bottom two rows show the Eau profile you are targeting, and the difference between the total Eau profile you have created and the target. In most cases there will be a difference shown, even after Calculate Best Additions is pressed because a precise match is not always possible. |
| o | If you find a large positive difference in a column after calculating the best additions, you should consider diluting the mix with distilled Eau, as likely your base Eau has too high a concentration of that ion. |
| o | For additional information, consider reading the articles referenced above or visiting our online forum. |
