Over the top freshness
If you need proof of the freshness of spices from The Spice House compared to any other source, just buy the ground cloves and keep them in a jar with a plastic lid. Little did I know when I made my first purchase 20 years ago, that freshly ground cloves have a very high oil content, and the vapors from that oil can melt certain plastics over time. When their product descriptions point out how committed they are to the best and the freshest, they are serious. And there is a bonus to this high level of freshness - less product is needed to obtain a better quality of flavor compared to other sources.
