These two land in different places. A vinegar is frequently on a cottage food list and an acidified infused oil rarely is, for exactly the reason that separates them everywhere else.

Why vinegar often qualifies

Cottage food laws cover products whose safety does not depend on a process somebody has to supervise. A finished vinegar at strength is hostile to nearly everything and the acid is doing the work on its own. That makes it a plausible candidate, and it is worth asking about by name rather than assuming from another preserved product.

Why an acidified oil usually does not

An infused oil carrying a low-acid botanical is safe because of a control that was applied correctly, which is precisely the thing cottage food law is designed to avoid having to oversee. Expect it to be treated the way an acidified food is treated, with a process behind it and somewhere licensed to make it.

Describe the product completely

What the base is, what goes in it, whether anything in it is low acid, how it is acidified if it is, whether the product is shelf stable or refrigerated, and where it will be sold. Leaving out the botanical is how a maker gets a confident answer to a question they did not ask.

Record who told you what

Name, date, what you described and what they said. Guidance gets restated and staff change, and being able to point at a specific conversation is a different position from remembering that somebody said it was fine.

Nothing here is a determination

This property is written from federal regulation, voluntary grade standards and published extension guidance. It is a starting point for that conversation rather than a substitute for it.

The shrub sits in between

A drinking vinegar with fruit and sugar in it is neither a plain vinegar nor an infused oil, and states treat it inconsistently. Describe it as what it is rather than reaching for the nearest familiar category, because the category you pick in the conversation is the one you will be answered about.
