Gypsum

(That's water to the rest of us!) Beer is about 95% water, so if you want to discuss water treatment, filtering etc this is the place to do it!

Gypsum

Post by iandiggs » Sun Jan 29, 2012 12:27 pm

Hello All Just wanted to ask you, how much gypsum should you put in your water/brew? The tub of it i got from wilkos said '28.3g per gallon' - that's loads, isn't it? I put 50-60g in about 3 gallons, boiled it and left it and the water's completely cloudy with a massive layer of white sediment at the bottom-surely that's not right!? I don't wanna spoil my brew.....

For what reason are you adding Gypsum?
Are you brewing from kits or All Grain, if its kits you don't need any at all, if its All Grain then it is determined by a combination of what the composition of your tap water is, and the type of beer you are trying to brew.

Beer o'clock recommended it for enhancing hoppiness:

"I found that water treatment changes the way hops come through into the brew. A simple addition of Gypsum to my water makes a phenominal difference.

Failing that, either use more of them or use different hops".

Taken slightly out of context but I stand by the statement. The original discussion was about getting the maximum flavour from hops. What I suggested was that it might be worth trying a gypsum addition because it worked for me. With my water. Without it my brews didn't have the character I was looking for.

As Steve says it is water and style dependent.

That's for making sherry, not beer.

As the others have said, the amount of gypsum you need in your brewing liquor depends on what sort of beer you're brewing and what your water is like. I have very soft water, and for a pale ale, I end up using somewhere in the region of 10-15g for a 22L batch.
