Hello do Campden Tablets ever go out of date?? I found a bag of Campden Tablets that I think are about 2years old can I still use them to treat my brewing water?
I would guess that they are still fine. WWI technology
I’m interested in this question, too. On average I brew about 12-16 times a year, and when I bought my first bottle of campden tabs in 2014, it was a bottle of 110…so. Using a quarter tab in both mash and sparge water, I’ll still have campden tabs in say…2027 to 2032!
Also when I use a liter or more of tap water for my starters I’ll very unscientifically “shave” a bit off of a Campden tab into the water prior to heating. I have no idea if this is helpful, or even detrimental.
Not that I’m aware of. You may be thinking of CaCl2, which does.
Yep, that’s what it was. My bad. Thanks, Denny!
I say that in a compressed tablet… which seems some what glossy… that tablet is preserved… short of bad storage. Sneezles61
Campden lasts forever as far as I know. I’m still using mine from >10 years ago.
I was just thinking my bag has got to be 6-7 years old at this point, and I haven’t noticed anything off.
No idea how old mine are. The label is all faded. I guess they still work.
