In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

Example input: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than  most.
Example output: 5
Example explanation: The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.
Q: Yum!  I could live off of this stuff.  The peach flavor is refreshing and delicious. It's no longer sold where I live, and I really miss it.  (Can't even get it from Amazon.)  It's just too good to be discontinued.
A:
