DetailsGypsum adds permanent hardness (calcium ions) to soft brewing water. Brewers that use distilled, or RO, water like to add some gypsum back into the water to give it some hardness. Gypsum can also be used to lower the pH of water. Use 1 teaspoon per 5 gallons.

4.9 / 5.024 ReviewsWater ChemistryIf you're an AG brewer do yourself a favor and pick this up along with a copy of your city's water report. Will improve mouthfeel of finished beer.November 11, 2012For All Grain you may need thisDepending on your water, you may need Sulfate, and you get that from Gypsum (CaSO4). Sufate provideds a sharper, fuller edge to highly hopped beers. So if you make IPAs (All Grain only), you may want to add 4 grams.December 1, 2012Use with soft well waterI use the gypsum with every batch of beer that I brew. I have a 225 foot deep well that has excellent water for brewing and I use the water from outside spigot for the first three gallons and switch over to water from the kitchen tap from that point on. The water from kitchen is softened and I use the gypsum to balance enough hardness. Seems to work just fine.October 30, 2017Purchased
over 2 years agoCa ionsI read that yeast like some Ca ions for optimum health. Seems to your work me.December 17, 2012Adds Sulfate for all grain brewersIf you make extract beer, you don't have to worry about your water, other than Chlorine. If you are an all grain brewer you may need this._x000D_Sulfate adds crispness to your hop bitterness. But too much will make your beer taste minerally._x000D_I started with my local water report, then down loaded the Brun Water spreadsheet, and entered the beer style to come up with the needed amount of Sulfate. I suggest you start low, and add a tiny bit to your individual beer and see if you like the taste._x000D_January 15, 2013SulfateI'm an All Grain brewer and I use this to add Sulfate and a little Calcium to my brewing water for IPA and other highly hopped beers. I use about a teaspoon. The extra Calcium helps too.January 23, 2013Water chemistryGood source of calcium and sulfate ions at a pretty low price.February 13, 2013for all grain brewers that use soft waterI use Gypsum when brewing All Grain IPAs and Pale Ales. I typically use 4 grams, measured with a precise scale. Depending on the style of the beer you are brewing, and the mineral _x000D_content of your water, you may need to add calcium and Sulfate, and Gypsum has both.March 11, 2013Good Stuff..Used this to help with mash water ph, and worked great. Would recommened.March 18, 2013Wish it was resealableGreat addition to my all-grain brewing, and nearly impossible to beat for this price! The only thing that could improve this is if it came in a resealable package.April 1, 2013
