I'm glad to see you mention Roederer Estates Brut, but I would recommend you purchase it in magnums or larger. It ages differently and becomes even more elegant. My favorite sparkling wine is their L'Ermitage.
(French wine exports are in their sixth successive year of decline. Thousands of winemakers have staged protests in the streets of France to demand government help over falling exports and a slump in domestic sales.)
This is a symptom of a socialist government. When you see the market reject your product, you go whining to the government! WIMPS!
