Question in regard to water chemistry. When, and how, do people add various “additions?” I have gotten the impression in some of the things I have read that some additions do not “dissolve” into the water easily or on their own. True/not true?
For example - Let’s say I have 4 gallons of mash water and I want to add 1 tsp of CaSO4 and .5tsp of CaCl2. If I just put the additions into the water as it heats up to 165, and then stir it and dump my grain in, am I good? Or should I have made the addition differently?
The reason I ask is sometimes I see that “additions should be added directly to the mash” or similar phrasing - I interpret that as meaning it should be done AFTER the grain is added. Seems like it would be hard to disperse it evenly if this is the case.
So, does it matter how these (or other) additions are put into the mash?
