Finally got to try this hyped up 
juice and I'm pleased.  If you like this flavor and are into drinking loose leaf tea, may I recommend "MateVana" from 
Teavana.  Teavana is a loose leaf tea importer with brick and mortar stores in fancier malls across America.  I'm not affiliated with them, I just love their tea and Matevana is pretty much spot of with Bobbas!  It's really good.
The flavor profiles are very similiar and MateVana is a great herbal tea that's really a coffee drinker's style of herbal tea.  
Here is a quote from their website:
"Taste this coffee-like, caffeine-infused mate and red rooibos blend. Sweetened with cocoa, chocolate chips, almond bits and enhanced with hazelnut, this mochachino wonder lends a Teavana favorite smooth, dark rich sips of that are soft and robust."
I highly recommend it!  Here is the link:
