I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...

The tea was a lot milder in flavor than I was expecting, but still pleasant. The aroma was light. I probably would not buy this again, but that's only because I would like a more intense flavor.
