Ex Input:
It may be all natural but it didn't have a natural taste to me.  The can size is small and the calories were more than I thought there should be.  I like the mild carbonation ok but I wouldn't switch from orange juice.

Ex Output:

Ex Input:
Was looking forward to this drink but was put off by its sweet soda-like taste.  Maybe it's an acquired taste? I'm not sure  but the high calories don't make me want to try.  Looking forward to a diet version.

Ex Output:

Ex Input:
I was so excited to try a new BOLD coffee.....needless to say, I am disappointed. I would rate this coffee as a MEDIUM. If it would have been listed as a MEDIUM, I would have given it a higher rating because this is truly a MEDIUM strength coffee in taste and flavor. I will still drink it from time to time- flavor is smooth, not bitter. Overall, I wish that I would have ordered some more Jet Fuel or Black Tiger.
