Just for general information.
There are over 120 different varieties of wild yeasts already classified.
Some are more appropriate in other uses , Like Wine, and Beer.
My mom used to make her own wine many years ago. She never used additional yeasts. Only whatever was on the fruit she used. Grapes,, apples,, Rosehips,, and probably other fruits. Her method was to use the fruit, without washing it. Washing the fruit would have rinsed of the necessary yeasts.
If you order a sourdough starter culture, you may like the faster results. BUT,, eventually, the yeasts will evolve/change to those in your climate. As well as what is in the flour you are using.
There are many tricks to cultivating a sourdough starter.
