From maureenclancy.com, a blog about matters of taste

SAN FRANCISCO - BALSAMIC HONEY VINEGAR is, first off, not really balsamic vinegar, the best of which comes from Italy. Rather, this tasty product is made right here in the ‘US of A‘ by a  fifth-generation family of beekeepers. It’s made from pure honey in the style of balsamic vinegar which involves fermentation and aging in oak among other steps.
I tasted it plain and loved the hint of sweetness and the sassy tang. It’s very smooth, without the “catch” in the throat of other vinegars. It’s available on-line for about $12 (8.5 ounces) at HoneyRidgeFarms.com and at Amazon.com.
