As a former barista at the coffee holy land, St. Arbucks, I believe that I should be forthright in my observations regarding coffee preferences among the peoples of the world who imbibe.
Some people like acidic coffee. Therefore, they may enjoy a cup of Dunkin' Donuts coffee. Not all people who like acidic coffee like Dunkin' Donuts, though. It's complicated.
Some people like a coffee with a strong body and a dark roast with low acidity. That would be somebody like me. My preference is not right, I just cannot stomach a highly acidic coffee like Dunkin'.
Some people say that St. Arbucks burns their beans. Fair enough. But, I would take an over-roasted coffee any day of the week over an acidic coffee. It's a taste preference. Not right and wrong.
If you disagree with me over my analysis, you may voice your opinion. I can take it. But I think we coffee drinkers need to come together and agree that I will not declare your preference for Dunkin' as wrong and I'd ask that you refrain from harping on the burned St. Arbucks beans. Whether burned or not, a lot of us enjoy a cup there because the body tends to be strong, the roast tend to be bold and dark, and the acidity remains low. That's a cup I can enjoy. You don't have to enjoy it.
My favorite is this one (also linked above).
