Ah that is why it is rebrewed. I do a mixed brew in a pair of quart jars. I fill about 2/3 w mate and water. Then I brew oolong tea and mix that strained tea w the mate that still has the mate leaves in it. I drink it w sugar. It's popular for the health and mood benefits it isn't consumed for flavor.
I've been drinking mate since before I could walk and I would disagree. It's an acquired taste but I wouldn't go so far as to say it's 'not consumed for flavor'.
I do something similar to what you do with mint tea instead of oolong for the summertime. A kind of terere cocido I guess lol.
