Example Input: First off,  let me state that I am not a fan of decaffeinated coffee of any type.  But I often have guests over who ask for de-caf, so I gave this a try.  While I agree with some other reviewers who have stated that there is a certain "different" taste about this blend, for me, it was not a bitter taste, but instead, a good, strong flavor that mimicked the strong (real) coffee taste I enjoy.  I had a second cup, and the flavor grew on me even more, and I thought: "it really is delicious for a decaf."  The aroma isn't truly satisfying (why does this always happen with decaf?) but I think many decaf drinkers will be used to that lack.  The package had to be snipped open with scissors --this is tightly packed!-- and then I just poured it into a zip loc for storage in the fridge.  I'll stick with regular coffee, but I'm sure my de-caf loving friends will enjoy this.

Example Input: The first time I tried this product  was 2 years ago at the Venetian spa restaurant in Las Vegas  having  a cup of tea with some friends. We all remarked how delicious and tasty it made our tea.  We've been using it ever since. A little goes a long way and I use it anytime I would ordinarily use a sweetener.  Since the artificial sweeteners are so unsafe and unhealthy and I have a sweet tooth, I felt this was a safe alternative. Not only is it safer, but there's no aftertaste and doesn't raise your blood sugar level. This particular stevia has absolutely no bitter taste to it. I've tried others before and since and there's no comparison.
