Over the years I have done a lot of research on this subject. I think this article from http://shelflifeadvice.com/content/how-long-will-they-really-last-part-I gives a good summary about the expected shelf life of spices and herbs.
What about dried herbs and spices? According to the experts at the Spice House in Evanston, Illinois, the shelf life of these dried products varies quite a bit depending upon the type of spice and the form it’s in. For example, peppercorns may last 4 years, but poppy seeds will barely last a year. As you might expect, whole spices will hold up longer than ground spices. As dried spices and herbs age, they oxidize and lose flavor. However, that doesn’t mean they’re dangerous or spoiled; it just means that you need to use a greater quantity to get the taste benefit you got from a smaller amount of fresher product.
I think a good rule of thumb in checking for freshness is if the smell is there then the flavor will be there.
To prolong the shelf life of your spices store them out of sunlight and away from heat.
Transfer your spices to glass containers. They will help preserve the freshness of you spices longer than plastic containers.
Over the next few weeks or so I will be experimenting with different themes, or skins for the Spice Rack blog. What that means for those who don’t know. The blog may look different as I experiment, until I settle on a look or style.
I’m partial to blue. I think this theme looks pretty good, if I can figure out how to change all the Green text to another color.
I’m also interested in your feed back so please feel free to express your opinion.
Or should I say Re-Launched. A few years ago This was a profitable web site, selling only spice racks. We made a decision to shut it down. We were selling the same spice racks on our main site.
Spice-Racks.com is owned by Condells.com. The purpose of this blog is to provide information in regard to using spices, and or how to store them. Of course we would like to sell you a spice rack. We will also provide you with other sources that provide spice storage solutions that we don’t. So Check out the “Where to Buy” page.
We invite your feed back on any information we publish, or products you may buy as a result of a recommendation from Spice-Racks.com.
