Pei Yuan-ling, who does research on the social and economic history of Taiwan and is currently an associate professor at Hung Kuang Institute of Technology, notes that Kukeng coffee has already become a regional product sold widely in central and southern Taiwan. For example, you can find it on sale at the Tzu Chi Buddhist Hospital in Talin, Chiayi.
從事台灣社會經濟史研究、目前任職弘光技術學院共同科副教授的裴元領即指出，古坑「巴登咖啡」目前已成為地區性品牌，行銷點擴及中南部，嘉義大林的慈濟醫院內都買得到巴登咖啡。
