I worked there. Many of the teas have fillers. Extremely poor treatment of employees. Employment is very fear-based, resulting in very fake and forceful sales tactics towards customers. Absolutely do NOT recommend.
I have tried a couple teas from Teavana – the Spice of Life White Tea, Youthberry White Tea, and Raspberry Riot Mate. I was very excited at first, but immediately noticed upon opening the bags that they were comprised of a lot of massive fruit chunks, spice bits, and not a whole lot of actual tea leaves.
Once I’d tasted them, I was even more disappointed with the artificial flavouring that left a chemical aftertaste in my mouth. I can’t speak for their plain teas, but it would seem that their flavoured teas are a lot more like Koolaid or flavoured water than real tea – and for the price paid for the amount of tea, it is definitely not worth it. If you’re a beginner to loose tea, I suggest going to a locally owned store instead and finding some more reasonably priced teas that are actually comprised of tea leaves, and not just a potpourri of add-ins.
