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: 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: This licorice is great.  It taste like the old fashion rope licorice. I will continue to buy it.
Example Output: 5

Example Input: Just got a new keurig and immediately went on a search for the best dark rich bold coffee (Caribou Mahogany) and other brands with rich taste (Wolfgang is winning so far) but really wanted to find the best hot cocoas and got these first...now trying to give them away. The are even worse than the packaged kind you get in the stores. Actually, I think I've found better instant ones. I hate to write a bad review but..if you want to find a DELICIOUS cocoa mix in the K-cups...get the Grove (Station) brand here on Amazon.  They are always sold out (which DUH I know why now as they are a far better tasting brand) but if you put your email on a wait list, they'll let you know when they come in and you dont have to wait very long.  I'd stock up though, as you'll find you want a cup or two every night! (and the dark, milk and peppermint combined box is the bomb!!)I just sent a couple boxes out to a friend of mine who was complaining about how bad the k cup hot chocolates were....she'll be thrilled to get my care package!!
