You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example input: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Example output: Positive
Example explanation: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.
Q: I like the aroma and flavor of coffee but many brands, particularly the big "S" brand, do a job on my stomach. I was anxious to try Puroast low acid coffee. I prepared it in a drip coffeemaker. I was highly disappointed with the brewed coffee. I don't use sugar in my coffee but this definitely needed it. The taste and aroma were awful. It has a burnt flavor, even for a French roast and extremely bitter aftertaste. The aroma was not particularly inviting either. I wish I still had my PH meter because I would have loved to test the acidity of this coffee vs. regular coffee. Based on the bitter aftertaste and how it reacted on my stomach, I'd guess it is anything but low acid but I have no scientific means to validate my subjective opinion. Frankly, even if it is low acid, I can't "stomach" the taste.
A:
Negative
