Example Input: Green Mountain "Nantucket Blend" K-Cups make a very good cup of coffee in my <a href="http://www.amazon.com/gp/product/B000AQPMHA">Keurig B-40 B40 Elite Gourmet Single-Cup Home-Brewing System</a>. This is a very smooth tasting brew that my wife prefers over the <a href="http://www.amazon.com/gp/product/B0029XDZIK">Coffee People, Donut Shop K-Cups for Keurig Brewers (Pack of 50) [Amazon Frustration-Free Packaging</a>] I generally drink in the morning.  These are good on both "Small" and "Large" cup settings as well.  Highly Recommended!  CFH
Example Output: 5

Example Input: I love this coffee. I do wish it came already ground as I don't have a grinder and use a blender instead. But it's worth it. Many flavored coffees I've tried only seem to have a flavored odor that doesn't reach the coffee, but this one manages both.
Example Output: 5

Example Input: This coffee is good and has nice subtle flavor. I am disappointed though because I looked at the bottom and it says decaf. I dunno bout you but I drink coffee for the caffeine. In the picture on bottom of box has text but it is so small I did not even consider looking on it. So just disappointed that is decaf and does not say on page when ordering.
