How yerba mate is manufactured?
Stages involved in producing mate.
1. HARVEST - By hand or using machines, the leaves and stems are separated from the tree.
2. COOKING - To stop the fermentation process after harvest, the leaves are very quickly exposed to the extreme heat of a naked flame (20-30 seconds).
3. DRYING - In the 24 hours following cooking, the leaves are dried to reduce the water content to 5-6%. This process is completed using a “Barbacuá”. The standard Barbacuá is a grill on which the yerba mate is spread in layers 30-40 cm thick, where it is exposed to currents of hot air at around 176-212°F.
4. GRINDING/SORTING - The leaves and stems are then cut into pieces for sorting. Depending on the origin, more or less stems will be removed to achieve the desired flavour, a flavour which becomes more refined and gentle with time.
