Blue Moon is the time of year when we have an extra full moon in a month. This year the blue moon was on the 30th of September. The was the day we opened our unique Blue Moon barrel. In this barrel we add the last remaining balsamic vinegars from our bottling sessions. It takes 12-18 months to get enough balsamic vinegar that has no real set amount of any one of our other great tasting balsamic vinegars. This barrel aged concoction comes to us on once in a Blue Moon, with a full body and complex flavors that are sure you get you wishing for more blue moons.
