Adding Gypsum to Beer
« on: March 01, 2013, 02:33:54 PM »
Not the mash or boil, but what about in the glass?  I thought I remember Mort (or someone) saying they added a pinch of Gypsum to the glass to accentuate the hops.  I brewed an AIPA with and without additives.  The one without has a subdued hop character.  Can I add some Gypsum to the glass and how much?

I can't claim to have tried it. I did try calcium chloride to interesting effect. I think it was Martin that was talking about that. maybe Kai? one of the water gurus

Of course you should be weighing it out to the nanogram and dropping a stir bar in your glass....just kidding! 

I've just added a few dashes of sulfate to try the effect and it does work.  It does take a while for the gypsum to dissolve though. 

If you decide to add a dose to a keg, then you probably should figure out what the dose should be and add that to the keg and give it a shake.  It should be dissolved in several hours.

Thanks Martin!  I dropped in a dash and it definitely sharpened up.  I think I'll try a side-by-side tomorrow and report back.  Very interesting.

I've added it to the keg before after dissolving a smaller amount in a 4oz sample.  Worked great.
