Vietnamese wine is wine produced in Vietnam. The area was first cultivated for viticulture during the French colonial rule of the region in the late 19th century. The region's tropical climate was ill suited for the type of Vitis vinifera that the French colonists were used to and the wine industry turned its attention to fruit wine production. The late 20th century saw renewed focus on the development of Vitis vinifera with the assistance of flying winemakers from regions like Australia. In 1995, a joint venture with Australian winemakers started an aggressive planting scheme to reintroduce international grape varieties like Cabernet Sauvignon and Chardonnay to land that was until recently littered with landmines left over from the Vietnam War.
Vietnam is located between the Tropic of Cancer and the Equator and has a climate typical of a tropical region marked by high humidity and a rainy summer season. The topography of Vietnam is very hilly which can provide some relief from the tropical influences and also create various microclimates where viticulture could thrive. The Gulf of Tonkin, Mekong and Red Rivers also have a tempering effect on the climate. Due to the year round warmth, vineyards in the southern region of Vietnam can produce a harvest up to three times during the course of a calendar year. Some plant varieties can produce fruit from new cuttings within a year of their planting.
