Gypsum in both batches....I had read somewhere that this was a good source of calcium for the yeast in sugar washes. Of course it is also a source of sulfur.

i think gypsum is just a source of calcium and magniesum? no sulpfur?


and i think it only is usful when used in a mash to lower ph? it reacts with some other stuff, or something along those line...other wise it's basic?

So in the 'stillers world it is said to be a good source of calcium for yeast health in sugar washes....this may be a myth that I latched on to in another life .
If google is to be believed gypsum is calcium sulfate dihydrate (chemical formula is CaSO4·2H2O).

you got me on this, i was thinking about dolomite! which is a blend of calcium and magnisium carbonate....and now i'm thinking about epsom salts, which i think is magnesium sulfate....
