Grandmaster Brewer
While weighing out water salts for my last brew it appeared that the volumes were noticeably smaller than expected. I measured them out and, sure enough, they were considerably smaller than the measured dosage. I buy my salts by the pound and store them in canning jars so it may be a year or two before I use the last of a pound. They do absorb water, even here in the desert, so I can imagine more humid climates are much worse.
I have always heard/read that weighing your salts is more accurate than measuring. I would argue that weights change much more quickly than volumes do as moisture is absorbed, so that accuracy diminishes greatly over time.
I suggest comparing measured amounts to weighed amounts periodically, especially if your salts have been stored for any period of time.
Here are the dry weight grams/teaspoon amounts for your reference:
Calcium Sulfate 4.0
Calcium Chloride 3.4
Magnesium Sulfate 4.5
Sodium Bicarbonate 4.4
