FYI the 'water crystals' for humidors are Propylene Glycol. This is
NOT something you want to ingest. Its one of the main ingredients in
automotive antifreeze.

The water crystals in the humidor are possibly a different compound,
but definately for a different reason. In the humidor it is to help
regulate humidity I assume. In brewing its for improving your mineral
profile of the water.
Water crystals are Gypsum (CaSO4) and Magnesium Sulfate (MgSO4).
Togehter they both help make soft water hard water. Gypsum is also
supposed to help settle out prooteins to help prevent haze.

Almost right but...
Ethelyne(spelling?) Glycol is the automotive antifreeze. Propylene
Glycol is normally non-toxic and is used in formulating liquid
medicines and also as an anti-freeze in RV water lines.

I seem to remember it being in "Spiced Cider Mix" I had years ago.
