Example Input: Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>
Example Output: 4

Example Input: Brew style: french press, espresso Smell: Nothing special here, decent 'coffee' smell with some earthiness.  No caramel notes, no sweetness. Taste: Mild, earthy, somewhat smokey, dirty mouth feel, finish is short.  I mostly brew with a french press but i tried it in my espresso maker just to see how it would fair.  The caffeine seemed very pronounced to me, there was no sweetness to speak of.  It did have a very nice crema though. Overall: I wont be buying this again, its nothing special.
