Of course!! It's not about the quality of the yerba or the mate, but how you make the mate, that's the important part. You pour yerba in 3/4 of the mate, shake it with your hand on the top of the mate, pour a bit of cold water to not burn the yerba, and pour hot water (80° - 85° degrees, NOT more or you'll burn the yerba). Now you can put the straw and drink. You can discard about the firts 3 mates cause they'll be a bit could ( cause of the cold water) and bitter, then you can start enjoying!! Haha it's all science😂
