Serious Eats: Talk
I'm one who doesn't believe what "they" say about them... keeping no longer than 6 months?!? As long as they still smell good and give off nice aroma when rubbed in palm... no way I'm tossing them.
Made herb/spice blends/rubs for holiday gifts TWO years ago. Bought BIG containers of stuff at farmer's market... it's still fine.
BUT have to say something for fresh-er dried stuff. My grandmother always said you HAD to put a few bay leaves into things like soup or stew. Wasn't until I actually bought bay leaves for myself that I even knew they even did ANYTHING for flavor??
