Somph:

The Freshest And Best Quality Seeds Are Usually The Bright Green Ones. Older Seeds Will Lose This Fresh Color Over Time And Will Become More Faded. When Buying Saunf, Look For Plump, Unwrinkled Seeds With A Strong Fennel Fragrance. Store Saunf In A Cool, Dark Place Away From The Sunlight In An Airtight Glass Container. A Spice Cabinet Is A Perfect Place Since Most Spices Last Longer And Retain Their Potency For A Greater Period Of Time If Stored This Way. Do Not Keep Fennel Seeds For Longer Than Six Months.
