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: I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...
Example Output: 1

Example Input: I had previously imbibed a couple other flavors of Switch beverages, and I liked them a good bit. This one was not bad, but certainly unremarkable. The kiwi flavor was not very prominent, and I had to really try to distinguish that there was any kiwi flavor at all. The berry is more what I tasted. Since I'd like the other flavors so well, I was expecting I'd like this one as well, but I didn't even bother finishing the drink. Other people might like it better, but I found it to be too sweet and not all that worthy of drinking.
Example Output:
