Maurivin B Yeast Storage

[Grancru]

I purchased a 500 gram package of Maurivin B wine yeast and will only be using about 100 grams. Is there any safe way to store the remaining yeast for use next year or will it be destroyed by oxygen? It wasn't cheap and I hate to waste it.

If it cannot be stored, can it be reproduced?

Vacuum seal and freeze it.

I've kept dried yeast frozen for a couple years.
