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: I am only drinking it, so it won't be wasted, and I have to rotate it with a Coffee People product, so I remember why I like coffee.  It is really wan. The strongest flavor profile is tin.  I love creme caramel and am a huge WP fan, but the flavor strenth and consistancy of this coffee does not impress. Choose another - you won't be sorry you did.
Example Output: 1

Example Input: At around a buck a can, very expensive for 8.3 ounces of carbonated apple juice (with lesser amounts of grape juice, aceola whatever that is, raspberry juice, and finally actual strawberry and kiwi juice, plus some vitamin C added).  With the 100% juice banner all over that can, you might be led to believe it's 100% strawberry/kiwi juice . . . it's not. Taste is not unlike a typical Strawberry soda pop, but not quite as good.  Expected sugar content (natural). 135 calories. I'm not likely to make future purchases of this one.
