Increase acetic acid content of vinegar by evaporation?

I have a bottle of 6% vinegar. If I leave the cap off, will water evaporation make the acetic acid percent increase? Or will the acetic acid evaporate along with the water?

Acetic acid has a boiling point of 118.1 Â°C so it is slightly less volatile than water.
The acetic acid % would increase
