Morning Thunder is an excellent name for this drink, but I have a feeling it might put some people off, as the tea is very good without being too whacky and crazy tasting. I was expecting a real potent punch, but upon reading that it had yerba mate in it, which I  drank in one of my favorite Chai mixes, I was sure it would be palate pleasing and I was right! This tea is very simple, as the ingredients list is short; roasted mate and black tea- no fillers, no funny stuff and no funky herbs and spices.  Upon further search on the internet of it I found out that Yerba Mate is an herb that is traditionally prepared as an energizing tea and consumed by natives of South American countries as it contains high concentrations of antioxidant flavonoids possessing potent free radical quenching activity.  It also includes several B vitamins, Vitamin C, Vitamin E, Beta-Carotene and Calcium. Mixed with black tea, the Mate tastes like dark chocolate, just a hint mixed with the tea, it's a subtle yet an eye opening experience upon the first sip.
