Why shouldn’t I boil my water for Yerba Mate?

Boiling the water for Yerba Mate is said to cause the leaves to burn thereby making them bitter. It can also be harmful to the person drinking Yerba Mate through the bombilla if it is too hot, causing burns to the mouth and esophagus.

We recommed that the water should be heated to about 150-160 degrees fahrenheit or about 65 to 70 Centigrade (Celcius). Ultimate you, the person drinking the yerba mate decides when the water is too hot or too cold.

If you don't have a water temperature thermometer to test the temperature of the water heating, a cooking thermometer that registers temperatures down to 150 degree will work, use the rule of thumb. If it is too hot for your thumb, it is too hot for your mouth.
