Freeze clas

Profile picture for user jo_en

can clas be frozen and then thawed and brought to temp for direct use?could  frozen clas be thawed and refreshed?

thanks for any help out there!

I've never done but I'd guess it will work fine. I've frozen various cultures and they were unchanged when thawed. My yogurt culture would get slower after about 3 months in the freezer so some degradation happens. 

Give it a try and post about it.
