Calcium chloride is usually used in place of Gypsum when sulfates are not desired. Calcium chloride will adjust your mash pH down. 1 gram in 1 gallon changes the salt levels by 72 ppm calcium, 127.5 ppm chloride and adds 180 ppm to the hardness.

Best Calcium Chloride Ever! As pure as mountain snow! If a calcium ion and two chloride ions got together this would be their baby.

Perfect size, very dry
I've purchased water salts from home brew shops that had large clumps. Not from More Beer! Perfectly dry (and stays that way in a Tupperware).

Purchased for use with RO water exclusively
I finally got to work on water chemistry. Since I'm not a chemist, I wanted to keep it simple. RO water, CaCl and some lactic acid sure did the trick regarding mash ph. I do add some gypsum for my IPAs, seems to help quite a bit.

Water Profile Addition
Are you using RO water? You'll probably need this to build up your water profile.

Great ingredient to hit your target water profiles
Use this to push your water around to get it where you want it to be. Love this stuff.

A must have to hit your brewing style
If you brew all grain and use RO water you must replace the calcium necessary for yeast health. I use this exclusively for malty styles an half and half with Gypsum for hoppy styles.

I love my Calcium
When I want my hops to pop, I use this stuff. Boom!
