(CNN) - French presidential frontrunner Francois Hollande chose to spend the final day of his first round campaign in the Ardenne, an area famous for that most Gallic of luxuries -- champagne. Some of the vintners he met there may well be disappointed to learn the Socialist candidate chose not to crack open that ceremonial bottle of bubbly after sailing to victory on April 22. CNN was informed he toasted with red wine instead. With 28.6% of the initial vote, Hollande will be pitted against incumbent conservative President Nicolas Sarkozy's 27.2% in a run off on May 6.
