Ex 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.

Ex Input:
Switch Orange Tangerine is ok but not what one might expect.  First of all, there is more apple and grape juice in here than orange or tangerine (this will not be a surprise if you are familiar with the other flavors as that is also true with them).  Switch basically is carbonated juice.  The taste isn't a bad and it is supposed to be healthier than soda (which can be debated).  It is a reasonable drink for snacks but if you are going to need several if you are actually thirsty.
