Dark Roast Coffee: Bold Flavor, Deep Roots

For those who crave a bold, intense coffee experience, few things rival a dark roast coffee. Known for its deep, smoky flavor and lower acidity, dark roast is the brew of choice for those who like their coffee strong and straightforward. But what makes dark roast different from lighter roasts, and how can you brew it to perfection?

Let’s dive into the rich world of dark roast.

What Is Dark Roast Coffee?

Dark roast coffee is made by roasting green coffee beans at temperatures between 430–450°F (221–232°C), often until the second crack, a point where oils begin to rise to the surface and the beans take on a dark brown, almost black appearance (SCA, 2023). This extended roasting process burns off much of the bean's natural acidity and origin flavors, resulting in a richer, fuller body and smoky or even bittersweet notes.

Common names for dark roasts include:

• French Roast
• Italian Roast
• Espresso Roast
• Continental Roast

Flavor Profile

Dark roasts are known for their:

• Smoky, roasted flavor
• Lower acidity
• Heavier body
• Notes of dark chocolate, nuts, and spice

These characteristics make dark roast coffee ideal for milk-based drinks like lattes and cappuccinos, where its boldness cuts through the creaminess.

Dark Roast vs Light Roast: What's the Difference?

Feature	Dark Roast	Light Roast
Roast Temp	430–450°F	356–395°F
Color	Dark brown to black	Light brown
Flavor Notes	Smoky, nutty, chocolatey	Fruity, floral, acidic
Acidity	Low	High
Caffeine Content	Slightly lower per scoop	Slightly higher per scoop
Oil on Beans	Visible	None

Dark roast may taste "stronger," but it doesn't necessarily have more caffeine than a light roast (Ristenpart, 2022).

How to Brew Dark Roast Coffee

To get the best from your dark roast:

• Grind coarsely for French press or medium-fine for drip
• Use hot but not boiling water (around 200°F / 93°C)
• Brew time: 4 minutes for French press, 2–3 minutes for pour over
• Water-to-coffee ratio: 1:15

Avoid over-extraction, which can lead to bitter notes overwhelming the cup.
