Changyu Pioneer Wine Co, China's oldest wine company and largest winemaker by sales, opened a new chateau in Shaanxi province on Oct 9 to further increase its product lineup and cater to a wider range of consumers.

The chateau integrating grape cultivation, winemaking, sightseeing and recreation is the first of its kind in the northwestern province to be developed to meet international standards, according to the company.
