I love the original yerba mate tea and wanted to try this chocolate flavor as a little treat.  The first sip you are hit with this strange smell, then the taste, very artificial, like their is stevia or some type of artificial sweetener in it.  I smelled it again and just took a few sniffs to really try and understand what it smells like, throw up, it smells like vomit.  I dumped my whole mug into the sink and i'm throwing away the entire  box.  Disgusting.
