Can you fill a liquor bottle with vinegar after taking it?

It is generally not recommended to fill a liquor bottle with vinegar after taking it, as it may not be safe. Liquor bottles are typically made of glass, which can react with vinegar over time and potentially release harmful chemicals. Additionally, vinegar can etch or damage the glass, making it unsafe for use.

It is also important to consider the intended use of the vinegar-filled liquor bottle. If it is intended for human consumption, it is important to ensure that the vinegar is food-grade and safe for consumption. Non-food-grade vinegar may contain impurities or contaminants that could pose health risks.

For these reasons, it is generally advisable to use a separate container for vinegar, rather than reusing a liquor bottle. This will help to ensure safety and prevent any potential damage to the bottle.
