Can brewing salts have a shelf life?

Post by banjokat » Tue Jan 28, 2014 4:22 pm

Hi all,
I've been going through my brewing kit ready for the new season and noticed that my stocks of Gypsum, Calcium Chloride, Burton salts and Irish Moss - all Brupaks labelled - have best before dates on. All are way out of date as I'd not noticed this before. Can these things really have a shelf life or is it just a marketing ploy. Thoughts appreciated!

Calcium Chloride especially can absorb moisture from the air, so you'll end up weighing out watery mush if you aren't careful :(

And of course similarly with DWB that contains the same. Kept sealed any of them will outlive you. ( having said that, I do not know how old you are :D )

They're exceedingly well sealed. Therefore I shall outlive them. For I shall drink them :D

"Best before" is not the same as "use by", although many people confuse the two...
