Example Input: I recieved a Keurig K-Cup Brewer for Christmas with sample cups of coffee and tea but no cocoa so I tried this brand and I like them but I haven't tried other brands yet to compare with. I would buy these again until I find one I like better.
Example Output: 4

Example Input: I bought this at a local gas station near my house and was excited to try it because I see it everywhere. It was nasty. I will never drink this crap again, I don't care how "good" it is for you. The taste is disgusting and I'd rather just drink regular water. Blah!
Example Output: 1

Example Input: As coffee in general, this Wolfgang variety was alright. However, I was expecting a "Creme Caramel" taste, or something similar, and I don't feel this delivered. I tried multiple cups at different cup sizes and this coffee just didn't do it for me. It is marketed as a flavored coffee, yet I could not taste anything beyond the flavor of coffee.
Example Output:
