Would you consider this a sign of oxidation or am I just genetically flawed? I honestly don’t think I’ve ever smelled this in a champagne before and we drink a fair amount of it.
It certainly could be a sign of oxidation. It could also be a Sign of Brett - Not common, but I have experienced it on one or two occasions with sparkling wine.
Could be. Did it appear oxidized in color? If not (and my first guess would have been), it is probably heat damage. What’s the story on the bottle’s provenance?
