is this for mate or terere?

Mate = Hot Teresa = Cold I do drink the Yerba with HOT water during the morning/winter & during the summer will drink with COLD water. It works on both cases.

Is there Kurupi mate without added flavor?

No it has flavor added, this is the original flavor though

What is the expiration date of this product?

I don't know.I grew up with yerba mate in the original country of yerba mate production(PARAGUAY)...It never crossed my mind of expiration of yerba mat..I figure somebody has to keep the yerba for 2 or 3 years(which most people dont) before goes bad...

i would like to buy 2 of each flavor. example: 2 mint y boldo and 2 Lime y mint. it would be possible?

Hello! Thank you for your interest in our product. There is another listing for only 2 kurupi Boldo Yerba Mate, and another listing for 2 lime. I would suggest to buy them separate click in the 2 different listings. I hope this information could help you Regards Claudia Pregliasco LATIN SWEET HOME
