Example Input: Soon as I got this bag of decaf I made a big mug and it filled my house with the wonderful aroma of high quality fresh brewed coffee.  It is very finely ground but I still used the same amount I normally do and it turned out great.  I added some soy milk, sat back, and enjoyed my rare treat of an after-noon coffee break!!!  Definitely will buy some of this for the winter months so I can treat myself to excellent hot coffee any time of the day or night!
Example Output: 5

Example Input: If you like your popped corn small this is for you. Taste is good and it is crisp yet tender. The only real complaint is it has a disproportional amount of hull.
Example Output: 3

Example Input: This cereal is difficult to find in the stores so I appreciate being able to purchase it through Amazon.  My husband really likes it and looks forward to the delivering of it every month.  Seems like an unlikely thing to look forward to, but it's the little things that count.  P. Looney
