I am considering making two starters, one inside and one outside my flat. Unfortunately I live in northern Germany, where temperatures can still sometimes drop below freezing at this time of the year. Should I try anyway to make an “outside starter” anyway or wait until the weather gets warmer?
RRD: Good question. You can always make the outdoor starter and bring it in when it is below freezing. The truth is we don’t know what happens to starters when it freezes repeatedly. Some species will die, but others won’t. It also makes me wonder what people did a thousand years ago in cold environments with their starters.
