Ten years ago, while surfing at Montana de Oro beach in Los Osos, California, David Karr had his first sip of yerba mate. Served by his Argentine classmate at the California Polytechnic Institute, Alex Pryor, the earthy South American supertea (rich in vitamins, minerals, amino acids and immune-stimulating phytochemicals) filled Karr with a sublime buzz — a focus and energy he claims gave him a new lease on life. “I immediately fell in love with it. The energy lift was unlike anything I’d ever experienced,” says Karr, now 35 and cofounder of Guayaki, the premier American purveyor of yerba mate. “I thought, ‘How come I’ve never heard of this before? I’m from California; we’re the ones who are supposed to know about this kind of stuff.’” A year later, propelled by that Californian curiosity and an entrepreneurial spirit befitting of an international business major, Karr took off for Argentina to find out more about its native yerba mate. He visited the lush rainforest plantations, where mate trees thrived beneath a canopy of hardwood trees, the cool shade helping to keep the mate leaves from turning bitter in the harsh sunlight.
