I posted on this 1 hour ago and it didn't show.....
We toured northern Italy last year and visited a small balsamic producer for a tour and taste.

We tasted their oldest, 150 years supposedly, and it was very thick with intense flavor. We purchased a 100ml bottle of 20 year old Cherry Balsamic for CAN $40.00.... The type of wood in the barrel imparts flavor as in the aging of wine. The balsamic is topped up as it evaporates using the previous years barrel and as the volume decreases is placed in ever smaller barrels until the oldest we tasted was in a 20 litre barrel. So the contents are not 100%, similar to a solara system for Port.
