I was lucky enough to visit Acetaia San Giacomo Balsamico facility in the Emilia Romagna part of Italy this past year. Ended up buying quite a few different Balsamico's after doing the tasting there. As others have said, you only use the good stuff as a light final dress to a dish. A little goes a long way. But it is pretty incredible stuff. Very interesting to visit the place and see how it is aged.
