Residual sugar is in fact one reason why Cotat declassifies/is declassified. (It varies from year to year, I believe, whether the wines are Sancerre or VdT.) The
INAO stipulates for white and rosé Sancerre that they must have under 4g/l residual sugar. Another reason is alcohol level, which must be less than or equal to 13% abv for all wines in the appellation (of all colors).
However, per a wine store website, Tanzer has explained w/r/t the rosé specifically:
"This wine is actually bottled without a vintage (but with 'Lot 2008' shown on the label). Cotat unilaterally declassified this wine from Sancerre in order not to find himself in the middle of a difference of opinion between two local authorities, one of which has declared that the parcel in question was incorrectly classified as A.C. Sancerre 80 years ago."
