Gran Reserva Rosé joins a range which added £15 million to the Chilean category at retail level in 2010, according to Nielsen figures quoted by Constellation.
The company also says Gran Tierra is the second biggest selling Chilean range in the convenience sector.
Constellation backed the brand with a £1 million marketing investment at launch. Recent promotions have included an on-pack competition offering a free flight to Chile and another offering balloon flights across the Andes.
The company said it plans to continue developing the range and introducing further promotional activity.
