A: Growing up, I recall the spice cabinet (which also doubled as the frosting and sprinkle storage area) in my own home as, well, overwhelming. For example, a bottle of curry powder that's been around a questionable amount of time probably won't make you sick … Many folks abide by a "six-month rule" when it comes to discarding most spices. I certainly can't afford to replace all of mine twice a year.
I have never been clear on the shelf life, so I keep 'em around.
Have any clue as to when is a good time to chuck them? The shelf life of spices vary, and you never really need to worry about them going "bad" like other foods do.
Good luck with the spice cabinet clean-out project.
I hope that after this you'll no longer warrant the "spice hoarder" tag.
It won't do any good taking up real estate in that congested spice cabinet of yours.
