Yerba Mate is drunk throughout South America. It is said to have the strength of coffee and the benefits of tea. Yerba Mate is a caffeine rich South American herb. It is dried over open flames giving it a slightly smoky flavour. It produces a coppery green infusion with a bittersweet, earthy and herby flavour. This is a great alternative to tea. We generously fill each bag with quality un-ground ingredients, making for a satisfying full flavoured brew each and every time. 100% plastic free tea bags and inner clear bag, both 100% compostable and biodegradable. Ingredients: Yerba Mate 50g - 20 x 100% plastic free tea bags Not only where our tea bags made from corn starch (and still are), so no nasty plastics in your cup, we also started packing our tea bags in a film made from fast growing eucalyptus tree cellulose, so no nasty plastic in landfill neither.
