My local brew store sells 'water salts' - a combination of magnesium sulfate and calcium sulphate.
I've nver heard of these two.
Anyone out there who has and would like to share?
Been on the site all evening, it's putting a dent in my homebrew stocks.
I brew double batches AG with both submersion and immersion chilling.
Been brewing for 15 plus yrs - or long enough that my heart-rate remains calm throughout the boil/chill (just happened recently)
Need some new...
