The Shangri-La Winery get's their grapes from a combination of grapes grown by villagers throughout the upper Lancang and Jinsha valleys in Deqin along with some of their own larger plantations in the same areas. The government is heavily involved with encouraging villagers to grows grapes which is also leading to some negative issues with livelihoods and food security as discussed in my GoKunming interview.
mmkunmingteacher, I would be very interested in learning more about your article and your work since this is a major part of my own research. Feel free to contact me via offline message. I will also actually have an academic article coming out on this topic later this year in a journal on culture and agriculture.
