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: Brew style: french press, espresso Smell: Nothing special here, decent 'coffee' smell with some earthiness.  No caramel notes, no sweetness. Taste: Mild, earthy, somewhat smokey, dirty mouth feel, finish is short.  I mostly brew with a french press but i tried it in my espresso maker just to see how it would fair.  The caffeine seemed very pronounced to me, there was no sweetness to speak of.  It did have a very nice crema though. Overall: I wont be buying this again, its nothing special.
Example Output: 3

Example Input: You order (and pay for)D.O.P. Certified San Marzano tomatoes but you will receive "CERTIFIED" which means absolutely nothing. A true SM tomato will have an EU D.O.P emblem on the label plus the Corsorzio San Marzano stamp. This is false advertising.  If you enlarge the picture shown you can see on the upper left side partially one of the stamps. You will not receive this DOP label.  You will  receive another tomato from somewhere in the region under the Cento name. Typical marketing hoodwinking. Amazon refuses to take returns on this item, so beware.
