Secado, a second phase of firing and can be done through two methods including “carijo” and “barbacua”.

Carijo

In this process, leaves are exposed directly to heat of fire and are referred as unsmoked yerba mate. In case of air dried yerba mate, yerba mate is flash heated with hot air and slowly dried with warm air at 175 degree F.

Barbacua

2. Dehydration

In this method, dehydrated leaves are cut utilizing machelets and wooden mills.

3. Aging

Beneficio or aging is of prime importance in the processing of yerba mate. This long term process may last from 6-24 months and play a significant role in developing flavor and quality of yerba mate. Shorter the time it takes, more bitter the taste will be.

4. Milling

Milling is the last step of yerba mate processing that involves the separation of aged leaves from sticks or twigs. After separating the leaves, they are grinded in blenders and the strength of yerba mate depends on the proportion of leaves. Yerba mate gives a stronger taste if there are large quantities of leaves.
