It's white! It's powdery! It's got calcium ions AND sulfate ions! With enough of this fine gypsum, you could make a cast for a broken limb, or a sculpture of your favorite object. Instead, I just use mine in stuff. But for ALL YOUR GYPSUM NEEDS, this is the thing. Can't say enough about this gypsum.

Use with soft well water
I 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.

All grain water treatment
I add two teaspoons for hoppy beers, one for others. It adds the Sulphate I need to get my hoppy beers to really stand out. Otherwise the hops are kind of on the dull side._x000D_

Makes the hops stand out
I use the Gypsum to add Sulfate to accentuate the hoppiness in IPAs. I use a teaspoon or more.

Enhance hop character
I use 2 teaspoons my reverse osmosis water to boost the flavor of my highly hopped beers like India Pale Ales.

Makes your IPAs taste better
The Sulfate improves the hops taste and bitterness. I add a table spoon for a strong 10 gallon IPA.

A must for darker All Grain beers
Just recently bought this to adjust the water in my Porter. Product arrived quickly and was in tact. The 2 oz. bottle is enough for probably 20 batches or more when you consider that you're adding 1.0-2.0 grams per batch depending on your recipe. It's a no brainer at $2 and some change. Highly recommended. Bottles are also reusable and seal nicely.

It's okay...
I've brewed both with and without this and for me I can't tell a difference. I have softened water but I filter it before brewing so that might be why. Ideally I try not to add unnecessary things to my brew.

I use it all the time for IPAs
When I adjust my water I add 4-6 grams to enhance the hoppiness. Just get a good scale because you don't want to be off by a quarter ounce.

Not totally sold
Maybe I'm just too new at this, which I'll accept, but I've brewed batches of beer both with and without this and I can't tell a difference. Maybe it really depends on the type of water you have...
