Sourdough English
Starter is kitchen slang for a mixed culture. It is not a clinical probiotic claim.
Pasteur explained living cells in a vat. English-speaking tables already had cheese, pickles and beer. The local lens names those foods without turning this into a starter recipe book.
Safety English still matters: botulism fears in home canning are not the same as lactic pickles. This atlas refuses process steps.
Local notes
Kombucha shelf
US grocery kombucha is a labelled drink. Alcohol and acid vary — read the label, do not invent a brewery at home from this page.
Pasteur’s year
1857 is a history mark in English textbooks, not the birth of fermentation.
Official pages own schedules and treatment. This atlas does not.
