How old are those bottles of spices in your cupboard?

Did you know that they get old and lose there flavor? A few years ago we started to once a year write the year of purchase on the top of each jar.

After they are two years we throw them away. Wouldn’t it benefit us all if the spice companies would put an expiration date on their bottles? Why don’t they? It seems like a really good product differentiation idea that could command a premium price.

Thanks to Nurit for this idea.
