Champagne vinegar is exclusively produced in the Champagne region of France. Just like Champagne itself, the vinegar has millions of aficionados in France and other countries. Considered the "king of vinegars" in France, its production process is unique and includes a carefully monitored aging in small oak barrels. Incomparably smooth and subtle, this light and mild vinegar is a good choice if you want to dress delicately flavored salads or vegetables (especially asparagus). Mix with a little nut or truffle oil to create a simple, yet elegant vinaigrette.
