Guayaki, Sebastopol, CA, has introduced San Mateo Loose Yerba Mate to its line of organic beverages. Sourced from the rainforest in the San Mateo region of Southern Brazil, this air-dried organic yerba mate offers “the lift of coffee, antioxidants of green tea, euphoria of chocolate and nutritional profile of wheatgrass,” according to the company. San Mateo Loose Yerba Mate can be brewed like coffee in a French press, coffee machine or espresso maker, or it can be enjoyed the traditional way—with a gourd and bombilla (metal filtered straw). The company offers San Mateo in an economy-sized 16-ounce bag.
