making of maté tea
What we call “maté” is actually just the liquor resulting from infusing yerba maté leaves in hot water. Fresh maté is not consumed in its raw form. The leaves are harvested and then flash heated in large dryers, or sometimes over wood fires. This is called “blanching,” and is very different than the processing of tea leaves from the Camellia Sinensis plant, which are not blanched but rather left to wither, then air dried at lower temperatures.
Once the fast “blanching” of maté occurs, they are slowly dried for 8-24 hours. This slow drying of maté brings out all kinds of different flavour characteristics.
Next, the really slow part begins: the yerba mate leaves are put in cement or cedar aging chambers, usually for 2-3 months, and up to 12 months! Once this meticulous process is over, the dried leaves are ground or broken up and ready to go.
