Mae Chedi is traditionally known for its tea plantations, but coffee has been introduced as a replacement for opium. Watchara "M" leads a 19-member coffee cooperative in the Mae Chedi region, where farmers borrow tea fermentation methods and apply them to coffee. These coffee fruits are fermented in closed HDPE bags for 5 days before being pulped, fermented again to remove the mucilage, and then dried on raised beds. This gives the coffee body, sweetness and complexity.
