Copper Cow Coffee | 14,543 followers on LinkedIn. Premium Vietnamese coffee on a mission to bring sustainability and a side of self-care to your daily cup. | Copper Cow Coffee was created to be an in-home barista experience that empowers anyone to fit a moment of coffee bliss into their busy lives. As a Vietnamese-Californian, founder Debbie Wei Mullin always loved rich and creamy Vietnamese coffee, but she also knew that despite being the second largest coffee exporter in the world, Vietnam’s coffee farms had been left behind in the global sustainability push. Above all else, creating better, more equitable opportunities in Vietnam is at the heart of Copper Cow Coffee.
