>>1445563 you gotta "treating" it
if it is a wood mate (name of the cup) you gotta put some yerba till is half full and put boiling water in it till the top, let it set some time 10 or 20 mins, the yerba will absorb the water, if so put some more water and let it rest for one day, if you do this the wood will absorb the flavour of the yerba and it will not taste like wood when you make one that is gonna happend if you listen to ther other anon, after the day clean it with warm (not boiling water) and dry it there you gotta a "mate curado" it is mean to drink unsweetened mate, sorry if bad english thirdworld fag here
