A large part of the reason for this trend is that because of climatic conditions in the Champagne region (about an hour drive northeast of Paris), only about half of the years in any decade will the weather permit for adequate ripening of grapes to make even ?just decent? wine. And while everyone nowadays says they like dry wine, most prefer a bit of sweetness in what they are drinking, especially in the United States. Another reason is that consumers expect that a particular producer?s product will be about the same from year to year, which usually requires blending of wine from a number of different harvests to maintain the anticipated consistency.
