Business sparkles at winemaker near Ukraine war zone Deep in the bowels of a former gypsum mine in east Ukraine, winemaker Rafail Nasyrov scrutinises a bottle of sparkling rose. Hundreds of thousands more line a winding labyrinth of underground tunnels and caves. The winery is located in a government-held town just two dozen kilometres (15 miles) from the frontline in Ukraine's low-level war, where the army and Russian-backed rebels continue to lob deadly artillery barrages at each other. But despite more than three years of fighting that has claimed some 10,000 lives, Nasyrov's employer, Artwinery, has never stopped production.
