How can I keep saffron fresh for longer?
There are special glass jars made to protect herbs from damaging uva/b rays, proven to maintain freshness.  Granted, these little jars are designed for a "different" kind of herb, I, on the other hand, use them for my ultra expensive, direct from the middle east saffron.  Keep an open mind and enjoy your saffron!!!
