Example Input: This was the most potent orange drink I have ever had. It might be "100% juice," but this drink has some kick. There are no artificial sweeteners in this drink, but it is so highly concentrated that it was overwhelmingly sweet and even the tang of the carbonation couldn't cute into the sugary flavor. It was WAY too strong for me and I thought it had kind of an odd aftertaste, but if you like carbonation and have a powerful craving for orange-tangerine, this is the drink for you.
Example Output: 2

Example Input: Thought this might be a nice alternative to use with my favorite coffee, but was sadly disappointed. It leaked all over - no matter what we tried and the coffee was weak, machine clogged with most attempts and water wouldn't brew thru. At times the cup even melted a little - leaving a nasty taste in the coffee. Go with the greener alternative and try the ekobrew - much better results and no waste.

Example Input: I tried this milk chocolate with hazelnuts for the first time recently after reading a review that this brand was the best chocolate in the world. I had to try it and it was worth every penny. I am a dark chocolate fan normally (70% is my favorite) but I have to say I would order this again and give it as a gift. It melted like butter in my mouth and was beyond delightful.
