The jar or packet at either of my local stores is quite big. How long does it stay effective, once opened? Given Star Anise is quite hard, I'm thinking it may last a while. But would I be better vacuum sealing half or 2/3?

You don't really need to vacuum seal it. You can store it dry in a sealed bag or container. It will last years. The flavour might deteriorate over time though.

    I think the flavour deteriorating over time is presumably exactly what the OP is asking about.

  • Fair, for a point of reference: I have a large bag of whole star anise and they are still fragrant after a year of storage Apr 5, 2019 at 20:27

    Freezing the spices is a nice way the flavour fresh for longer periods of time Apr 5, 2019 at 20:28

    Yes it is the fragrance I'm concerned about. I was assuming they cant go 'off'.

They should last a long while if properly stored in an airtight container in a dry place.
