After much success with my starter, I'd like to store some for future
use and as a reserve in case something goes wrong with my main
starter. I'd also like to pass some on to friends and family via post.

In your experience, which would be the best way to do this - dry and
freeze? If so, how long would a sleeping starter last in the freezer
and still be viable? Should it be mixed with an anti-freeze, say
glycerine, before hand?

Many thanks for all replies.
