Calcium carbonate (aka chalk)

[HerrSchnapps]

Brewing the case-swap stout again, but we need chalk for the water chemistry... anyone know where one can source food-grade chalk?

Wigram! :) That's were I got mine from last time.

Otherwise Brewer's Coop stocks it...

I think Linwood has it aswell..... P.S. Calcium Carbonate

I'd say most HB stores will have it, mine came in one of the little infamous black and white brewcraft baggies.

On a side note - Calcium chloride is a little harder to find but Mike at Brewer's Coop got some in recently.
