I don't drink coffee, but I am an absolute sucker for a good tea, hot or iced. Starbucks' Iced Chai Tea Latte is one of my favorites, but at $4.88 each, I am perfectly happy to make my own at home. As long as you use a pre-made chai tea concentrate, it takes only minutes to throw one of these together.
I also think that it look super cute in a mason jar, and the jar makes it easy to travel with.
