Example Input: At last- a decaf coffee that doesn't taste decaf! Smooth, rich, flavorful, with no bitter aftertaste. Starbucks worthy (but to my husband who doesn't care for Starbucks, it's way better). We like to drink this in the evening and it's basically dessert with cream and sugar.
Example Output: 5

Example Input: Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.
Example Output: 5

Example Input: This water is delicious. I'm not picky, but I can taste bad water with chemicals or metal taste and this has none of that. And at 50 cents per bottle, delivered to your door, it's a great price. I have a teenage son and he drinks these all the time and it's a-okay with me. Better than drinking a coke.
