Starbucks intentionally over roasts their beans well past the ideal roasting point. They do this to ensure a consistent flavor across locations, but to me it just tastes like shitty burnt coffee.

At the end of the day, Starbucks is a coffee chain in name only. Their menu is largely milk-based and many of their products happen to have some coffee in them, so I guess it doesn’t matter too much if the coffee component is sub-par.
