Reducing balsamic vinegar typically takes about 15 to 30 minutes, depending on the desired thickness and intensity of flavor. To reduce it, simmer the vinegar in a saucepan over medium heat, allowing it to evaporate and concentrate. Stir occasionally to prevent burning and achieve a consistent reduction. Keep an eye on it, as the process can vary based on the amount of vinegar and the heat level used.
You cannot usually substitute balsamic vinegar for cider vinegar. The flavor profiles are quite different. However the chemical properties are similar, so the actual answer depends on the particular situation.

Well I'm 13 teen years old and I'm pretty sure that "aged balsamic vinegar"is like not sour but you know that like tart taste i guess and with age like whine it gets better.So the second one sounds good.The first one I'm almost positive that the one is healthier cause it's light.well that's the best i can do like i said I'm only 13 teen.wishing you best cooking!=)------That's not really very helpful but I am new here so I will leave it in case I am supposed to.Aged balsamic vinegar has been aged.Reduced balsamic vinegar has been reduced in volume by boiling. It is thicker because there is less water content. One how-to on the subject says it should take under 5 minutes to accomplish.Basically you put 4 times as much vinegar as you need into a pan, heat it over heat low enough not to caramelize or burn it, and wait for it to "get smaller". It is often used as a garnish on sweet potato dishes.Traditionally, balsamic vinegar was aged for a minimum of 12 years. This type, however, is now rare and expensive. The second grade is aged for less than 12 years, and can in some cases not be aged at all. The third grading level, which is what you probably have, is not made at all in the same manner. It is, in effect, imitation balsamic. It is made by adding color and thickener to Wine Vinegar.According to Wikipedia, the 2 higher levels are labeled in one of these ways:"Aceto Balsamico Tradizionale" (top grade made traditionally)"condimento balsamico""salsa balsamica""salsa di mosto cotto"So if you are looking to try Aged balsamic, you should really go for one that at least tries to be authentic. There is really no reason why aging would make the imitation type better.
wash them in vinegar to make them shine for a long time
