I see a difference between drying something out and salting it (or sugaring it) even though both remove moisture, and a difference between fermenting something into vinegar and/or alcohol, and using those substances to preserve something directly, even though, yes, you won't have alcohol nor vinegar without fermentation. Similarities as well! This taxonomy wouldn't be a well-formed tree.
