[EX Q]: Zen brews up to an golden amber liquor. The aroma is sweet spearmint. The blending of this tea is excellent--spearmint could be overpowering but they use just the right amount of it. Slightly sweet spearmint is the primary flavor, then you taste a hint of lemon. The green tea provides an herbal base for these two flavors that makes the intial impression of zesty spearmint and lemon modulate into a substantial potion. Very nice and satisfying with a clean spearmint aftertaste.  Remember that this tea does have caffeine--however, it does not say how much on the box. A good estimate might be 30 mg--compared to 90mg for the average cup of coffee. Make sure you time how long you brew this tea because if you brew too long it becomes bitter. Four minutes is ample.
[EX A]: Positive

[EX Q]: I have had waffles from other mixes that are too sweet.  I have also made them from scratch. I like my waffles with NO Sugar in them, because I don't like too much sugar.  This mix is very good.  Waffles are just the right consitancy for me and the mix is easy to prepare.
