La Matera refers to the container in which Mate is consumed. Actually, "La Matera" doesn't mean this, but we created this name referring to it. In Argentina, we call Mate both the infusion made from its leaves (caffeinated herbal beverage) and the container in which it is consumed, with the most common one being the gourd, although there are many different models made from various materials. It is consumed using a bombilla (metal straw with a filter), removing all the tea leaves to leave only the delicious and refreshing taste of this infusion.
It represents unity and sharing, helps socialize, facilitates the creation of bonds, extends or promotes conversations, shortens distances, helps create intimacy, relaxes, and informalizes. It serves as an excuse to meet up: "It's typical to say, 'Do you want to come have some mate?'"
