Revel Berry has a delicious raspberry and blackberry flavor. It's easy drinking and clean tasting, and not too sweet. Guayakí (gwy-uh-kee) Yerba Mate (yer-bah mah-tay) is made from the leaves of the celebrated South American rainforest holly tree (ilex paraguariensis). For centuries, South America's Aché Guayakí tribe have sipped yerba mate daily from a traditional gourd for its powerful rejuvenative effects. These rainforest people find tremendous invigoration, focus and nourishment in yerba mate and revere it as the "drink of the gods". Guayakí's Revel Berry is a flavorful tribute to the Aché Guayakí and their legendary beverage. Rise up with Guayakí and share in this powerful rainforest experience! Guayakí’s mission is to steward and restore 200,000 acres of South American Atlantic Rainforest and create over 1000 living wage jobs by 2020 by leveraging our Market Driven Restoration Model.
