Example Input: This is a really dark roast coffee which I usually like.  It has a bite to it but the bold/complex flavors and aroma weren't quite there by my taste.  I tried it in a coffee press, drip and a steam coffee machine that we have at the office but couldn't find that sweet spot that would make it work for me.  I'm a little bias because I picked up <a href="http://www.amazon.com/gp/product/B001EO5PB0">Jeremiah's Pick Coffee Colombia Supremo Decaf Whole Bean Coffee, 10-Ounce Bags (Pack of 3)</a> at about the same time to compare and absolutely love Jeremiah's.
Example Output: 3

Example Input: So being Gluten Free is hard, especially in a dorm. But I have gotten really good at making Gluten free pancakes on an electric frying pan. They are super yummy! I also make these really yummy cheesy garlic biscuits. This stuff is heaven sent! Makes food that is reminiscent of "normal food"
