I was curious and looked on the tazo website.

For Tazo Awake English breakfast tea the label says “based on tea brewed with freshly boiled water for 5 minutes (no milk, no sugar), an 8 fl oz cup typically contains insignificant amounts of calories, fats, carbohydrates, sugars, protein and sodium”.

Seems weird for yours to have such a significant difference even if its a slightly different type, could you post an image?
