Example Input: I drank this coffee over 30 years ago when I lived in The Netherlands. So glad that I can get it through Amazon. Strong, full bodied but easy on the tummy!!!
Example Output: 5

Example Input: My Scotties were full of hot spots and when I used this within a week all the hot spots were gone. The smell is kinda strong, but not bad. It's tolerablel.
Example Output: 5

Example Input: As a French Roast fan, I bought this brand of K-cup with high expectations, considering the name attached to it. I was disappointed. It has a hearty aroma and full-bodied flavor but leaves a bitter aftertaste.  If you're a lover of the more robust roasts, I would recommend trying the <a href="http://www.amazon.com/gp/product/B002L41Y8A">Coffee People Kona Blend Island Style, Extra Bold K-Cups for Keurig Brewers (Pack of 50)</a> instead. It is a smooth blend with none of the bitterness that delivers that kick you're likely looking for.
Example Output:
