Labeled Cuvee Terroir I instantly thought cuvee Terrible. Hugh Johnson notes in the 2005 Pocket Enclyclopedia of Wine that "Beware of a whiff of rot in many of the Gamay-based [sic] wines." Chinon is supposedly Cab. Franc but the rot is there in this one so much so that I would have to say this Chinon should no(t) be drunk.
I let it sit, the funk settled sown but the wine that was left was a tad sour and bitter, I let it sit over night, tried it with a hamburger, there is still wine in the glass. I really hope this is a flaw but I don't know what it would be, it was not corked that is all I know for sure.
On the Dale scale a solid D (at best).
