I'm relying a lot more on BrunWater for my lighter-than-amber beers, and finding that just about every beer calls for some combination of CaCl2, gypsum, and epsom. Here's my current SOP:I read somewhere that gypsum dissolves better in cooler water, so I've been heating my strike water in a kettle, while dissolving the salts separately in a small beaker of ~1 cup cool water. Then I put strike water and salt solution into cooler box mash tun, and wait until it drops to strike temp, then slowly stir in the grain.
The problem I'm running into is that the CaCl2 does not dissolve very much. (I think it's the CaCl2, because I've never see this problem with some brews that just called for gypsum & epsom.) It stays all flaky in the beaker; I've tried dissolving it in 2-3 cups water; no dice. When I add that "solution" to the mash tun, the flaky white calcium just drops to the bottom. I'm assuming that it is doing no good, since it's not in solution...
So is this a problem? if not, I'm fine. But if so, how do you dissolve all your CaCl2?
