Example Input: Gevalia is the best coffee there is - always mellow, never bitter. I'd never drink any other brand.
Example Output: 5

Example Input: This has a great rich taste. Remember this is ground whole leaf, so the tea is stronger than you may expect. Not overly sweet and dissolves readily. I use it during workouts mixed with ice water in a Polar bottle.
Example Output: 5

Example Input: Tried these the other day because of the low price and regreted it from the moment the jar was opened. These sausages tasted like card board soaked in beef flavored vinegar. Im used to eating Glazier's pickled sausages that snap when you bite them. Guess I will stick to what I like.
Example Output:
