Default expiration dates?

How long will these additives keep before losing effectiveness or going bad?

yeast nutrient
yeast energizer
wine tanin
citric acid
campden tablets
potassium metabisulfite

I don't make a whole lot of wine, so it might be a while before I use these up anytime soon lol.

The tannin and nutrient and energizer will last a long time- I'm not sure it ever goes bad.

The sorbate is the only thing I see there that I would replace after a year or so. It might not go bad, but it may lose effectiveness, resulting in bottle bombs! The rest of the stuff is ok, I believe.
