I use and highly recommend using the Brunwater spreadsheet available here, https://sites.google.com/site/brunwater/
My mineral additions are based on my mash volume and my sparge volume so they will be different based on your system. My water is 100% RO.
These mash water additions are based on a 3.9 gallon volume of mash water.
7.8 grams of Gypsum
2 grams of Baking Soda
1.6 grams of Calcium Chloride
These sparge water additions are based on a 5.83 gallon volume of sparge water.
11.7 grams of gypsum
2.3 grams of calcium chloride
0.8 ml of lactic acid
These additions are also based on my grist for this brew so unless your grist is the same as mine these additions might not be ideal.
Here is the water profile I used.
Calcium - 153
Magnesium - 0
Sodium - 44
Sulfate - 296
Chloride - 55
Bicarbonate - 112
Estimated Mash pH - 5.4 Measured mash pH - 5.5. Added enough lactic acid to bring it down to 5.2.
All this being said your personal preference may be different than mine. You might prefer less sulfates or more chloride. The above additions make for a great beer for my tastes. Also kudos to the Brunwater spreadsheet. I am always within 1 point of the estimated pH on the spreadsheet so if you don't have a pH meter this is a very handy tool to have.
