Are you talking about their black coffee? Or their other sorts of drinks that are often less than 50% actual coffee? Because if anything, the usual complaint about literal coffee at Starbucks from people who like coffee is it tastes too much like coffee, in the sense of being over-roasted and uninteresting. Even their blonde roast is still at best a medium roast at any other modern roaster.
The thing that surprised me about burnt coffee beans is that people assume that the heavier the taste the more caffeine is there and that’s not true of over-roasting. It’s less available caffeine, not more. So it tastes terrible for no practical reason.
