hi everyone..on a respite from a grant proposal and reading the forum to relax I thought, once again, of one of the most pestering questions I have had: are the exorbitant prices attached to the various balsamic vinegar bottles really really worth your money? The acidity (which was the most important detail based on articles I had read a long time ago when I first discovered this heavenly concoction) is the same across the board: cheap, expensive all have it at 6%. There are differences in the sweetness of the vinegar but I have bought expensive bottles (I consider $25.00 for vinegar a lot-or am I wrong?) that were less sweet than cheaper versions. Almost all claim to be from Modena, almost all are imported, so where lies the truth? I have seen in various delis here in town and upscale supermarkets tiny bottles for $100.00. Let me pick your brains please.
