Turning the yerba
Act of moving the mountain of yerba to the opposite side, revealing the dry slope of yerba. Turning the yerba is used while drinking mate traditionally, when it starts to become tastless on one side and is usually performed with bombilla. The final result of turning is new mountain of yerba with dry slope that can be refilled with water to get more fresh taste from yerba mate.
