Example Input: I usually enjoy a cup of coffee a few days a week, more as an indulgence than as a necessity.  It's a sipping beverage for me, and flavor matters a lot.  That said, I add milk and sugar, so I'm not excessively picky (or I think so, at least).  So I'm always glad to find new "gourmet" blends to add to my list of favorites.  This blend seemed promising, with a very nice aroma and a perfect, even grind.  I usually grind my own beans, but found that this grind worked nicely in my espresso machine as-is.  It even produced a rich, smooth crema.  Unfortunately, my first sip - without sugar or milk - was very bitter.  I ended up adding about a half-teaspoon more sugar than I usually use just to compensate.  Even then, the coffee flavor, itself, was thin and weak.  With just a little milk added, it tasted more like, well, flavored milk.  This coffee reminded me of the inoffensive bland coffee my parents used to get for our drip coffee maker a couple of decades ago.  Fine for that application, but not really what I'm looking for in rich, smooth flavor with low bitterness.

Example Input: These chips taste awesome. And unlike most other flavored chips, they actually make sure that plenty of the flavory salty goodness gets on each individual chip. Just don't pass gas near any pretty ladies after consumption. They'll totally know it was you.
Example Output: 5

Example Input: WASA Crisp'n Light inside packaging cannot be recycled.  The crackerbread is excellent, but its inside packaging is a cellophane or type of plastic that cannot be recycled anywhere in the six states I have contacted.  Todate WASA has not revealed what the inside packaging is made of, nor where I can recycle it.
