Hi all. I've had my stuff stored for almost a year now, and havent'
had the opportunity to make wine in that time (shocking, I know). As
I unpacked my wine making goodies, the pink cleansing solution looks
pretty washed out, which got me to wondering...

what would the shelf life of the various chemicals be, like potassium
sorbate, yeast nutrient, sodium metabisulphite, pectic enzyme,
bentonite and acid testing kit?

Thanks!

Julie
