Cao Bang black grapes

As one of the first units to introduce the black grape variety for trial cultivation starting in April 2019, the black grape cultivation model of CAB Green Technology Investment and Development Joint Stock Company (Da Quan hamlet, Hung Dao commune, Cao Bang city) has yielded positive results after more than two years of implementation. The company invested in a system of covered greenhouses, an automatic fertilization system, drip irrigation, and cultivation processes according to VietGAP standards to ensure product quality.

To ensure sustainable development and high and stable economic efficiency, the vineyards have implemented day-trip tourism, both to introduce and promote the product and to allow visitors to tour the vineyards.
