White wine was smokin'!

[wineguruchgo]

I'm serious! I've been selling and drinking wine and I have never seen this happen before. I opened the bottle for a customer at 1pm. Wine was fine. Then I uncorked it for another customer at 3pm and it looked as if there was smoke in the bottle and I watched it come from the bottle while the customer was trying it.

Any ideas as to what this could have been. Very, very strange.
