French champagne maker: We can't let Russia water down our brand

French champagne producer Michel Drappier loves Russian customers. He sells them thousands of bottles every year, the national airline serves his brand in business class, and it was on the menu when Vladimir Putin visited France. But Drappier worries a new Russian law on labeling imported champagne will undermine the principle he holds sacrosanct, that only champagne produced in France's Champagne region is worthy of the name.
