Example Input: This is good coffee, but nothing to write home about. I like the grind, which is finer than most ground coffee, although I prefer grinding the beans myself. It has a bold, but not bitter, taste. Even though I'll stick to Eight O'Clock as my coffee of choice, this one certainly isn't objectionable and is better than most cups you'll get at the diner. And it's certainly better than Folgers, MH, and other grocery store brands.
Example Output: 3

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: Possibly THE best salt and vinegar chips (healthy or not) ever! The salt is just right and compliment the vinegar's tartness perfectly. All the chips are good.. salt and pepper can be a little overwhelming.
