I have some old stuff that has been stored appropriately but some is close to 20 years old.

If the powder is kept cool and dry, in a sealed container, it can last 50-60 years without issue. Smelling the powder is a good indicator of its condition, a solvent or ether like smell is good, a bitter acrid smell is bad. Rusty coloured powder on the kernels is a dead give away to powder going bad as well.
