Some time ago, we managed to purchase a couple of bottles of wine that were completely unpalatable. These particular bottles were purchased from a local supermarket so our bad experience should not reflect on the quality of cantinas in our area. Before throwing it out, we asked our friends to give us their thoughts. Pursed lips and screwed up faces told us everything we needed to know. We were poised to pour both bottles down the sink when one of our friends suggested we use it to make balsamic vinegar. Under his guidance, we topped up the bottles with white vinegar and sealed them with cheesecloth and rubber bands. They are now breathing and ageing in our cellar...to be tasted in 12 to 18 months!
