In the bowl of a food processor, combine the sparkling wine, cranberries, and vinegar and pulse until the cranberries are broken down, but still have bits of texture. Transfer to a mixing bowl and add the remaining ingredients. Adjust the seasoning to your taste. Spoon a bit of the sauce over shucked fresh oysters and enjoy!
