Lonely Planet
This coffee farm has been in the family of Rolan since the 1860s. It's part of a K'Ho coffee-growing cooperative that ensures that profits are directly supporting the K'Ho minority farmers. The beans are Arabica, including varieties grown in Africa, which are rarely found in Vietnam even though it's the world's second-biggest coffee producer. If you call Josh and Rolan in advance, you can stop by to see the plantation and pick up some Fair Trade, locally roasted beans.
They also stock beautiful traditional weavings done by the K'Ho women in the community. Predominantly blue and intricately embroidered, each takes weeks to complete; prices start from 1,200,000d.
