Mineral water on tap

General Homebrew Discussion

I’ve recently expanded my keezer capacity and want to have a keg of mineral water on tap.  I can’t seem to find good info on a mineral content to use.  Any of you have a profile you like?

From what I’ve seen, R.O. water that’s remineralized for flavor generally uses Calcium Chloride and Sodium Bicarbonate. I’d use them in balance and at low levels to start. You can always dissolve more in a small amount of water and add if needed.

This probably has more info than you’ll ever want or need: https://blog.khymos.org/2012/01/04/mineral-waters-a-la-carte/

I keep carbonated RO on tap as often as possible and have been thinking about this as well, what I’m hoping to find is a good mineral profile that I can make with the limited salts I keep around (Gypsum, CaCl, Salt, Calcium Carbonate).

So far I only tried a gypsum heavy batch that I liked but the girlfriend did not.

Thanks for the info.
