Chilean wine producer Viña Tarapacá is to develop a new range of sparkling wines in the wake of its purchase of Chile's Cuvee Mumm winery. "We bought Cuvee Mumm, which is in Casablanca Valley, and Tarapacá is planning to produce first-class champagne there," company president Carlos Cardoen said. "We bought this winery and we are going to modernise it and learn how to make champagne."
