In addition to the other suggestions, consider alternating the source of the mate. Argentinian and Brazilian ones are quite distinct in flavor. Lowering water temperature may lighten it a bit as well.

May refer to the demeaning origins of the name. Wikipedia:

   In Brazil, traditionally prepared mate is known as chimarrão, although the word mate and the expression "mate amargo" (bitter mate) are also used in Argentina and Uruguay. The Spanish cimarrón means "rough", "brute", or "barbarian", but is most widely understood to mean "feral", and is used in almost all of Latin America for domesticated animals that have become wild. The word was then used by the people who colonized the region of the Río de la Plata to describe the natives' rough and sour drink, drunk with no other ingredient to sweeten the taste.

This is very good. Sometimes it was some kind of guessing game to choose a kernel release to use in our environment.
