Dark roast reaches 455–475°F, well into second crack. Sugars carbonize — the sweetness tips from caramel toward charred and bitter. Acids break down almost entirely. Body is maximum. Bitterness is prominent. Origin character disappears; what you taste is primarily the roast itself.
This is not a criticism of dark roast. It's a description of what dark roast does and why drinkers who want it want it: they want weight, intensity, and an unchanging profile regardless of origin. The roast is the flavor.
Acidity: near zero. The acid compounds that cause reflux and brightness are destroyed at dark roast temperatures.
Body: full to very full. Maximum oil extraction, maximum textural weight.
Sweetness: low. Carbonized sugars read as bitterness, not sweetness. Dark roast that reads as sweet is actually medium-dark.
Bitterness: high. This is part of the value proposition for dark roast drinkers. The bitterness is the character.
Drinkers who want intensity above all else. Anyone who drinks coffee with milk and wants the roast to punch through. French press drinkers who want weight and body. Anyone who experiences acid reflux from medium roast — dark roast is the medical recommendation for acid-sensitive drinkers.
Not an early morning coffee if you want to actually taste it. An aggressive dark roast at 6am before the palate is awake is bitterness without nuance. Save it for midday.
