Vinegar makes the perfect compliment to Olive Oil in salad dressings, marinades and sauces. We've carefully hand selected the best of the best in every category of vinegar. To take the confusion out of balsamic vinegar, we've come up with our own rating system! The new "Sciabica Level" system gives you a way to choose your balsamic vinegar for every use. The levels take into consideration age and more importantly percentage of grape must used in production. For instance an L1 is a young balsamic with about 25% grape must, an L4 is aged many years with 100% grape must. One is not "better" than the other, but will rather be a choice based on the intended use.
