Freeze dried culture packs storage time in freezer

Does anyone have an idea what the usable length of storage is for the packets?
Thanks

Hi
The best before date is written on the packets or bottom of the container(when capsules).
In general - The cultures would be viable for min 2 years after the date of manufacture if stored at room temperature. More than 2-5 years if stored in a fridge and around a decade stored in the freezer.

Thanks for that info. That is exactly what I was looking for
