Out of red wine vinegar

The workhorse acid for anything savory and cooked. Sharper and less fruity than balsamic, which makes it the better choice when you want the dish brighter rather than sweeter.

Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.

What to reach for

Instead · 1

sherry vinegar or apple cider vinegar

one for one

What it gets you
The same acid strength in the same place — a dressing, a braise, a splash at the end.
What it costs you
Sherry is nuttier and better; cider is fruitier and softer. Neither is a problem.

Instead · 2

white wine vinegar

one for one

What it gets you
The identical thing without the color, which matters only in that a vinaigrette stays pale.
What it costs you
Almost nothing.

Instead · 3

lemon juice

half as much again

What it gets you
Acid, fresher and brighter, which suits a raw salad better than vinegar does.
What it costs you
Keeping. A lemon dressing goes dull overnight and a vinegar one does not.

Where the swap will be tasted · 7

These need it and are short enough that nothing hides: 4 required ingredients or fewer, which makes red wine vinegar a quarter of what is in the pan. Make the swap a decision rather than a repair.

Check what else is in the pan

The company red wine vinegar keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
