I just opened a bottle of "white red wine" (a Blanc de Noirs) from 2010. I must confess, I really don't know much about wine.
The cork looks weird to me, as if it was "moldy". It's a bit blueish-green around the edges. The wine smells pretty good, and the cork doesn't smell bad as well.
Is there anything to worry about?
