I am trying to make a balsamic style vinegar. Is there any Italians from Modena Region (or others knowledgeable) that make balsamic vinegar that can comment?
I have a batch of vinegar that got a pungent smell. I dumped it and started some new batches. They have the expected vinegar aroma not the pungent aroma. I have no idea why the one batch smelled pungent and noone has been able to explain it. I am guessing that I left it too long and the vinegar turned into something else or I didn't get enough air into it and some anaerobic bacteria beat out the mother. The articles I have seen on vinegar making are pretty sketchy. Does anyone have details on vinegar making and how balsamic vinegar is given that unique taste?
