You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: Dynasty brand green tea is the best green tea I've ever tasted.  It never tastes stale, unlike brands I've bought in grocery stores.  This is because each tea bag is packed in a sealed envelope with a metallic lining.  The metal apparently keeps out moisture.
Example Output: Positive

Example Input: I like strong coffee, but I don't want it to taste burnt or have an acidic after taste. Caribou Coffee's Mahogany is full bodied with a nice balance of dark notes and acidity.  It's one of my "go to" coffees when my favorites like Coffee People's Wake Up Call are out of stock.
Example Output: Positive

Example Input: Melitta Cafe is a smooth, flavorful coffee that compares well with regular coffee.  This is not the typical weak decaf blend that is true of many American brands.  Melitta has a rich, deep taste and a nice dark color.  Tastes great black or with cream.  As a stand alone coffee (no cream/sugar) it has a smooth, though strong flavor just like regular coffee.  This coffee is especially great as an after dinner drink.  Strong enough to taste like regular coffee but decaffeinated so it will not prevent sleep later.  Great coffee.
Example Output:
Positive
