Example Input: According to the side of the can, it's 100% juice with a balance on the carbonation. It tastes great if not for the chalky aftertaste. The low carbonation made it feel less of a soda and more of a juice. I probably wouldn't buy it in the store because of the weird taste.
Example Output: 3

Example Input: I like the taste, but the light roast was too light for me.  I find myself brewing smaller cups of coffee, hoping for a stronger taste.  Next time, I'll go for a medium or dark roast.  I think it was the medium that I had before and I really liked it.
Example Output: 3

Example Input: I finally did the research on this temptation treats and I'm glad to see that my suspicions are correct. I have been buying this treats for my kitty for years and suspected them all along to be the cause of him vomiting. Ironically, I even bought the hairball ones to see if they would make him stop vomiting. Now is official, I stopped giving them to him as often, and then monitored him whenever I gave him any. It soon became clear to me that he only vomits whenever I give him this treats. Sometimes he would vomit within minutes, and other times he would vomit during the night or the next morning, but if I give him this treats, I'm sure to be cleaning up orangee throw up off my carpet soon after.  I think is a matter of allergy or sensitivity to one of the ingredients, and they probably don't do anything to other cats but I'm never buying this again for my kitty.
