Making vinegar from red wine

Question:  How do you make vinegar from bottled red wine?
ebarenb

Answer:  Leave it uncorked at room temperature for a while.  Air oxidation of
the alcohol (ethanol) in the wine will form acetic acid aka vinegar.
Be careful with your taste test, though.  There isn't a whole lot of 
quality control involved here!
