I want to ask how to convert my spoiled wine to vinegar (follow-up on this question). Is this on-topic here?
Producing vinegar is fermentation of alcoholic beverages; it's just that it's away from alcohol to acetic acid. A number of the principles that homebrewers adhere to would apply, and there are beer styles where an acetic flavor is acceptable.
I personally don't have a problem with it, but some of the other moderators may have a reasonable argument against it.
I'd say your question is off-topic.
You don't brew your spoiled wine to make vinegar. You just store it somewhere so that it turns into vinegar by itself.
If a question is about non-alcoholic beverages it's on-topic if it's about making a tea or coffee. (I'd say more generally, if the beverage is hot at least in one of the steps of making process)
From the Oxford Learners Dictionary for brew:
- [transitive, intransitive] brew something to make beer
This beer is brewed in the Czech Republic.
- [transitive] brew something to make a hot drink of tea or coffee
freshly brewed coffee
- [intransitive] (especially British English) (of tea or coffee) to be mixed with hot water and become ready to drink
Always let tea brew for a few minutes.
