Example Input: This hot chocolate is pretty blah. Not very chocolatey and certainly not very strong. It's not the fault of the Keurig -- the Cafe Escapes Dark Chocolate is way better.
Example Output: 2

Example Input: I would not order these K-cups again.  Maybe I'm spoiled with Godiva hot chocolate, but I think Swiss Miss hot chocolate has more chocolately flavor than these K-cups and I wouldn't waste my money on these.  It comes out a pinkish color that is not appetizing at all.
Example Output: 3

Example Input: The first time I tried these, I thought, "WOW!" but I quickly found they were just too darn spicy and tart... Hard to enjoy the potato-chippiness of them when your mouth is under seige.
Example Output:
3
