What a great idea! I've been drinking a tablespoon of apple cider vinegar in water before meals, because it's been shown to reduce the postprandial glucose/insulin spike. The taste is...well, you can imagine. Balsamic vinegar has a much mellower flavor--I can't wait to get some Pellegrino and try it.
