Teach me why I should hate it- from a product point of view- not the capitalism argument. I think Starbucks in store coffee is the best that is easily available to me...
I believe the correct term for what's wrong with Starbucks coffee is "scorched." They scorch their beans during the roasting process.
Having said that, not sure you should hate on them. As the McDonalds of espresso (and I mean that in a good way) they provide a known quantity in serving coffee almost anywhere in the world. And being so ubiquitous, they have educated the palates of so many people that scorched coffee has become the de facto standard against which millions of people now measure coffee. Add to all that the fact that they're happy to let you have a business meeting there, or work all day on a laptop, while providing generally excellent wifi, and I have a lot of friendly feelings toward Starbucks.
