Mate is an infusion made with yerba mate leaves (Ilex paraguariensis), a plant native to the basins of the Paraná rivers, Paraguay and the upper course of the Uruguay River. These previously dried, cut and ground plants form yerba mate, which has a bitter taste due to the tannins in its leaves. For this reason, there are those who like to sweeten the mate a little with sugar, stevia or a non-caloric sweetener. The foam that is generated when "priming" is due to the glycosides that yerba mate contains. This product allows for keeping water hot at the perfect temperature for drinking Mate.
