Really, all I need is a place to store mash and sparge water salt amounts after I calculate with Bru'nwater.
I haven't built a recipe with it yet, but plan to soon. Maybe I can play with it at work today for a bit.
If you have your water profiles with salt additions required to meet your target, when you add that water to your recipe BeerSmith asks if you want to add the minerals to your ingredients. When selecting yes, it will add the minerals required to meet your target based on the amount of water you added to the recipe.
When the salts are added to the recipe, they default to being used in the mash. You can then double click and change that to boil, primary, etc.
For example, I am going to probably do is this:
1. Recipe calls for 5 gallons strike water and 4 gallons sparge water
2. Create a water profile including the needed salts and have one name appended with "strike" and the other with "sparge"
3. I can then add 5 gallons of strike water >> select yes to add minerals
4. Then add the 4 gallons of sparge water >> yes to add minerals
5. Edit the sparge mineral additions and change the "Mash" to "Boil"
Doing the above is sort of a pain, but at least everything is in the ingredients list. However, with two separate waters in your ingredients, even if they are the same water just different amounts, then on the mash tab, the water in the Estimated Mash pH says "Mixed Profiles."
I don't know how having two different water profiles in your ingredient list will affect the pH calculation.
