Getting my grains crushed and equipment ready to brew tomorrow.
If I were to weigh my water chemical additions --about 3 grams each of gypsum and calcium chloride–and simply dump those in the bottom of my dry brew pot today, would air or moisture cause them to lose their effectiveness by tomorrow about 24 hours from now?
I always sweat the details on stuff I don’t know about.
The Calcium Chloride will liquefy and cause rust spot on equipment if left too long on a metal surface. Since you taking its mass prior to its change from a solid to a liquid you should be fine. My chemistry is a little weak, since Martin didn’t seem concerned then I’m sure your good to go.
