Task: Sentiment Analysis
Input (English): I have tried this coffee hot and iced,with milk and black and I tested the pH.  Frankly it won't qualify as a great cup of coffee.  The flavor is burnt (like Starbucks dark roast) but is flat and it lacks middle notes and vanillins (unlike Starbucks.)  Perhaps flavors other than French Roast would be better at providing complexity as that frequently comes from Colombian roast in a blend. The aroma is underwhelming.  The pH of the Puroast coffee tested at 6.5, slightly acidic (neutral is 7 on a scale of 0-14.0) but less so than normal coffee.  Normal coffee ranges from around 5.0 - 5.1, more neutral than beer or any fruit juice and similar to carbonated water. If you can drink those, then your stomach isn't reacting to the acidity but something else. So normal coffee, whether it irritates you or not, isn't all that acidic.  Acidity generally refers to a flavor note in coffee rather than pH and coffee without acid flavor notes tastes flat.  Irritation may instead come from the essential oils in the beans or the caffeine.  (Having too much stomach acid has exactly the same symptoms as too little stomach acid and most people over 35 are slightly deficient in hydrochloric acid and 50% of people over 50 are seriously hypochlorhydric, but we are taught to regard the symptoms as being from acidity. Your Tums work by other mechanisms, beyond the scope of this review.)  So while Puroast is attempting to solve an acid/base problem that doesn't significantly exist, the fact that the flavor is low probably means that the essential oils in the beans are lowered as well, making the coffee less irritating.  Frankly I'd rather add about 20% chicory to good coffee, which slightly sweetens the taste and is less irritating.  <a href="http://www.amazon.com/gp/product/B0001M11HI">Frontier Natural - Chicory - Roasted, 1 lbs</a>Is it worth giving up flavor to drink coffee?  Your call, but I wouldn't bother with the Puroast French Roast.
Output (English): Negative
