I have a question concerning brewing salts. I’m coming up on the one year mark since incorporating them into my brew days (it would be hard to overstate how much learning my way around Bru’n Water has benefited my beers) and realized that I’ve been using the same batch of salts that I originally purchased a year ago. I mostly use Calcium Chloride, Gypsum, Pickling Lime and Lactic Acid – can anyone recommend an expiration date for these items? I haven’t had any issues, but wanted to head off any potential problems due to keeping them around for too long. FWIW, I keep them sealed in Ziploc bags.
