Example Input: This is good coffee, but nothing to write home about.  I like the grind, which is finer than most ground coffee, although I prefer grinding the beans myself.  It has a bold, but not bitter, taste.  Even though I'll stick to Eight O'Clock as my coffee of choice, this one certainly isn't objectionable and is better than most cups you'll get at the diner.  And it's certainly better than Folgers, MH, and other grocery store brands.
Example Output: 3

Example Input: My son made this.  He didn't have the patience to be precise about the water temperature and when, half an hour before it was done, it appeared not to have risen at all--I feared for the worse.  Determined to be polite, I agreed to have a sandwich using the bread.  It was amazing.  Apparently it rises during the baking or something.  Great tangy flavor (perfect for a meat sandwich imho) and not heavy at all.  Fortunately we had lots of deli meats, since the whole loaf disappeared within the hour.  We've had all but the sourdough peasant bread so far; I'm sure that will be delicious as well.
