Chile's leading wine producer Concha y Toro has posted rising third-quarter sales and earnings thanks to increasing exports and an easy comparison on the year.

The company, which has so far this year seen a weak Chilean peso hammer earnings, saw net income leap 37.3% to CHP5.6bn (US$10.7m) for the three months to 30 September. Revenues were up 8.9% to CHP61.6bn.

Concha y Toro said the result reflected a "strong export performance" and lower costs compared to the corresponding period last year.

The company, which produces brands including Casillero del Diablo and Trio, did not give a quarterly update on its performance on export markets but said shipments rose 13.3% in the nine months to the end of September. When measured in US dollars, export revenues were up 17.1%.

However, Concha y Toro continued to struggle at home with sales in Chile down 5.7%. The company blamed "strong competition in the mass-volume wine segment" as a 14% leap in volumes was offset by falling prices.

Nevertheless, the company insisted its performance had been better than its domestic rivals, leading to an increased share of the Chilean wine market during the quarter.
