Why do Starbucks beans taste burnt?
They dont to everyone, but its true they roast their beans by design much darker then many prefer. This is partially because they make so much more espresso roast as compared to anyone else. Since they need so many beans, they find that roasting beans from many different growing areas to a very dark roast enables them to offer a similar taste regardless of bean origin and initial flavor characteristics. But even when they were smaller, their coffee always had a slightly burnt taste (to me and many others, at any rate), so its also a company preference. Kopi will of course use a dark espresso roast, but not one in which the sugars have caramelized into carbon as completely.
