I've noticed that most (non-specialty) places that sell coffee tend to have very dark roasts. This includes Starbucks, any Fast Food restaurant, most nicer restaurants, and hotel coffee.
I can't tolerate anything darker than Starbucks' "Blonde Roast". All their others I'd consider to be dark roast. When I buy coffee in the store and make it myself, it's never anywhere near as dark as what you get in shops. I usually get fresh beans from The Fresh Market or Caribou brand.
Is there any reason shops tend to make their coffee so dark? Or is my taste just skewed from most people's?
