Keeping track of your water chemistry pays off with outstanding tasting beer! 
If you have soft water and are brewing a hop forward beer, you’ll want some Gypsum on hand. Gypsum (calcium sulfate) is used to add permanent hardness to your brewing water in the form of calcium ions, which will increase the hop perception in your beer. 
1 gram of Calcium Sulfate in 1 gallon of water changes the salt levels by 61.5 ppm calcium, 147.5 ppm sulfate and adds 153.5 ppm to the hardness.

Bought this with the LaMotte water test kit to boost sulfate for brewing IPA. A pound ought to be a lifetime supply for a homebrewer.

Needs re-sealable bags
I have had to clip the bag shut, and then put inside another zip-lock bag. It would be nice if these came in re-sealable bags.

Essential for Hop-Forward Beers
Want your IPA's and Pale Ales to shine? Give this stuff a try and it will really bring out the hops. Of course you should get your water tested before using it.

Gypsum Seems good
