No. It's vinegar. That sweet balsamic flavor. Supplication and Consecration definitely develop some vinegar over time.

I've seen that argument used before but I dont buy it. Lots of bottle conditioned beers oxidize like crazy (ever had a 10 year old Bigfoot?) and the lambics do produce acetic acid (Cantillon Kriek, Hanssens Oude Gueuze). I'd be curious to see some experimental data on just how much O2 yeast can eat. How much O2 will HEALTHY AND FRESH yeast consume? 10 ppm? And that's in the presence of lots of unfermentable sugar and amino acides, not to mention zero alcohol, where they can thrive. I suspect that the O2 in the headspace is A LOT more than what the yeast can consume.
