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: Nothing but good feedback from everyone. A very good classic tasting licorice product. We buy it on subscription and save shipping and a little money.
Example Output: 5

Example Input: These chocolates are a welcome find.  They taste the same as regular chocolate but they don't spike my blood sugar.  I treat myself to a couple at a time when I have a sweet tooth.  It's great to be able to satisfy my craving without the extra sugar.  And fortunately the Maltitol doesn't seem to bother my digestive system.  They're a little pricey but I found a great bulk deal at another online source.
Example Output:
