Hi

,
Ayup, I do sourdough. I make about 10# of bread weekly. The original starter was given to my uncle abt 40 years ago from a friend in Germany. Weāre in SoCal.
Eventually, no matter where your starter originates, it will be colonized by your local yeasts. Unless you keep it under lab conditionsā¦
I abuse the heck out of mine, and it just keeps trucking. Once itās stable, and you get a feel of it, itās very easy to keep going.
Mine stays in the fridge.
Are you on Twitter? If so, I can point you to several people that have extensive threads on wild yeasts.
Patience is needed because not much happens fast with sourdoughā¦
