So, what is real balsamic vinegar?
Fake balsamic vinegar
The court ruled in 2019 that balsamic vinegar is a generic term commonly used to designate a sweet-and-sour vinegar taste. This vinegar can be labelled “Balsamic Vinegar of Modeno” (Aceto Balsamico di Modena) even if it isn’t made in Italy.
Balsamic vinegars produced domestically in the United States are made from wine vinegar blended with grape juice or grape “must”. They may contain ingredients such as grape juice, wine vinegar, rice vinegar, caramel coloring, brown sugar, guar gum, and corn flour. In the United States, products are also allowed to be labeled as “Balsamic Vinegar” based on the U.S. labeling laws.
