The word sourdough doesn't mean much these days, a bit like the word natural. Obviously I'm talking commercially here, if you make sourdough at home you don't care, as long as it works plus easier to look it up on the internet.
What else do you call it?
How do people know you make it without yeast, conditioners, etc.
It's bloody hard, I don't think Naturally Leavened or similar will ring too many bells, most have just learnt the word sourdough.
