Hi,
Thanks for the reply !
Sorry about soapy, I realised afterwards that it probably wasn't the most helpful of descriptions.
I don't think that the wines in question were oxidised.
The problem has been the opposite of ' dead with little life or tang ' more a case of the wines having an aggressiveness and intensity of flavour that doesn't suit Sancerre and the finish always has a more than subtle hint of detergent or what I call ' soapyness '.
What was odd was that these aggressively flavoured wines apart from the Les Grand Groux were from the same producer and vintage as some perfectly good Sancerre.
I even took the four bottles of Fournier Sancerre off the same shelf on the same day and two were fantastic !
The smell in the bottle ( of the bad ones ) was close to how Sancerre should be..green and nutty with no real hint of how intense the wine was going to taste but in the glass you could just detect a slight difference.
But it was only an exaggerated Sancerre smell, nothing off putting
We should have taken them back after tasting them , but sadly, we drank them.
Each time it was only one bottle between 4 so by the time we'd all agreed that the wine was ' soapy ' the wine was gone.
