I tried this ready-to-drink (RTD) tea yesterday. I paid $1.99 for it at one of the local markets. I was prepared not to like it, but was surprised. It was fresh tasting and pleasant. I had a subtle experience that the beverage was salty, but that's unlikely because it has no added sodium. Probably my body chemistry. I'm conflicted in my opinions on bottled and canned teas, but I think this unsweetened option would be a much healthier alternative to soda when you crave something other than water.
Andrew Weil and Ito En have combined efforts to produce a line of healthy canned beverages. I've previously tried the Sencha Shot (I was so-so about it) and Partea Lady recently reviewed the Oolong Shot. (Company info here.)
