French roast is stronger in taste. It's bold, dark, and smoky. Colombian coffee is stronger in actual caffeine content and flavor complexity. They're not really competing on the same terms, which is why this question trips people up. "French" refers to a roast level. "Colombian" refers to an origin. You can have a French-roasted Colombian coffee, and it's actually pretty common. Once you understand that distinction, the whole comparison starts to make a lot more sense.
Wait, French vs. Colombian Isn't an Apples-to-Apples Comparison
This is the thing most coffee articles skip over, and it matters. When someone says "French coffee," they almost always mean French roast, a very dark roast style that produces a bold, smoky, low-acidity cup. It's a roasting method, not a place of origin.
Colombian coffee, on the other hand, refers to where the beans were grown, the farms and cooperatives in Colombia's high-altitude growing regions. Colombian beans can be roasted light, medium, or dark. They can even be roasted to a French roast level.
So the real question is: how does a dark (French) roast compare to a medium or light roast of Colombian beans? That's what we'll break down here.
French Roast vs. Colombian Coffee
| Category | French Roast | Colombian Coffee (Medium Roast) |
|---|---|---|
| What it refers to | A roast level (very dark) | A country of origin |
| Caffeine content | Slightly lower. Dark roasting breaks down caffeine. | Slightly higher. Less roasting preserves more caffeine. |
| Flavor profile | Bold, smoky, bitter, low acidity | Sweet, bright, caramel, citrus, clean finish |
| Acidity | Very low. Roasting burns off acidic compounds. | Medium. Lively but not sharp. |
| Body | Heavy, oily | Medium to full, smooth |
| Bitterness | High | Low to moderate |
| Origin character | Mostly masked by roast | Clearly expressed. You taste the terroir. |
| Best brew methods | Espresso, French press, drip | Pour-over, espresso, drip, cold brew |
| Who it's for | People who want a bold, no-frills dark cup | People who want complexity, sweetness, and clarity |
The Caffeine Question: Which One Actually Has More?
This surprises a lot of people. Dark roasts, including French roast, actually have slightly less caffeine than lighter roasts, not more. The roasting process breaks down caffeine over time. The longer and hotter the roast, the more caffeine is lost.
Now, the difference isn't dramatic. We're talking maybe 5 to 10% less caffeine in a dark roast versus a medium roast, measured by weight. But if you're measuring by volume (scoops), dark roast beans are physically larger and less dense, so you end up using fewer beans per scoop, which can widen that caffeine gap a bit more.
Colombian coffee, typically roasted medium, retains more of its original caffeine content. So if caffeine is your primary goal, a well-roasted Colombian medium roast is actually the better choice, and it tastes better too.
Flavor Strength vs. Caffeine Strength: Two Different Things
This is where most of the confusion comes from. When people say a coffee is "strong," they usually mean one of two things:
- Strong in flavor: bold, intense, bitter, heavy. French roast wins here. The dark roasting process creates compounds that taste powerful and assertive.
- Strong in caffeine: more stimulant effect per cup. Medium-roasted Colombian coffee wins here, because less roasting means more caffeine preserved.
French roast tastes stronger. Colombian coffee (at medium roast) is chemically stronger in terms of caffeine. Neither is objectively better. It depends entirely on what you're looking for in a cup.
What Happens When You French-Roast Colombian Beans?
It's a real thing, and it's actually one of the most common combinations you'll find in grocery store blends. Colombian beans are widely available, consistent, and relatively affordable at scale, so they're a popular base for dark roast blends.
The result? You get the body and boldness of a French roast, but the underlying bean quality of Colombian Arabica means it's smoother and less harsh than a French-roasted Robusta blend. The origin character, the brightness, the sweetness, the caramel notes, mostly disappears under the dark roast. What you're left with is a bold, smooth dark cup without the rough edges.
At Evan's Oro Negro, we don't French-roast our Colombian beans. We roast them to medium, because that's where the actual flavor of the coffee lives. Dark roasting Colombian beans is a bit like buying a premium cut of steak and cooking it well done. Technically fine, but you're leaving a lot on the table.

Which One Should You Choose?
It really comes down to what you want from your morning cup:
- Choose French roast if you want a bold, smoky, low-acid cup that tastes intense and assertive. Great for people who drink their coffee black and want something that hits hard on flavor.
- Choose Colombian (medium roast) if you want a cup with complexity, natural sweetness, and brightness. Something that actually tastes like the place it came from. Better caffeine retention, more nuanced flavor, and more versatile across brew methods.
- Choose both if you want options. Keep a medium-roast Colombian for pour-overs and mornings when you want to actually taste your coffee, and a dark roast for espresso or those days when you just need something bold and simple.
We're obviously a little biased toward Colombian medium roast. It's what we built Evan's Oro Negro around. But the bias is earned. When you source quality beans from the right regions and roast them carefully, you don't need to hide anything behind a dark roast. The coffee speaks for itself.
Frequently Asked Questions
Is French roast coffee actually from France?
No. French roast has nothing to do with France as a coffee origin. France doesn't produce coffee commercially. "French roast" is simply a roasting style that became associated with the bold, dark coffee that was historically popular in French café culture. The beans used for French roast can come from anywhere: Colombia, Brazil, Ethiopia, Vietnam. It's purely a description of how dark the beans were roasted.
Does French roast have more caffeine than Colombian coffee?
No, actually the opposite is true. Dark roasting breaks down caffeine over time, so French roast typically has slightly less caffeine than a medium-roasted Colombian coffee. The difference isn't huge, but if you're chasing caffeine, a medium roast is the better bet. The bold flavor of French roast can make it feel more stimulating, but that's a perception thing, not a caffeine thing.
Why does French roast taste so much stronger if it has less caffeine?
Because "strong" in flavor and "strong" in caffeine are two completely different things. Dark roasting creates bitter, smoky compounds, specifically things like guaiacol and other pyrazines, that taste bold and intense. That flavor intensity has nothing to do with caffeine levels. It's just what happens to coffee beans when you roast them at high temperatures for a long time.
Can Colombian coffee be roasted dark like a French roast?
Yes, absolutely, and it's done all the time, especially in commercial blends. Colombian beans are a popular base for dark roasts because they're consistent and widely available. The result is a smoother dark roast than you'd get from lower-quality beans. That said, dark roasting Colombian beans masks most of what makes them special: the brightness, the sweetness, the origin character. At Evan's Oro Negro, we roast our Colombian beans to medium specifically to preserve those qualities.
Which is better for espresso, French roast or Colombian medium roast?
Both work, but they produce very different shots. French roast espresso is bold, dark, and bitter with low acidity, classic Italian-style espresso. Colombian medium roast espresso is brighter, sweeter, and more complex, with caramel and citrus notes in the shot. Neither is objectively better. If you want a traditional dark espresso, go French roast. If you want a specialty-style shot with more nuance and sweetness, Colombian medium roast is the move. We pull our Colombian beans as espresso regularly, and the shots are exceptional.
