The age-old debate over which roast level tastes better—dark, medium, or light—doesn’t have a simple answer. It all comes down to personal preference and what kind of coffee experience you’re looking for. Do you enjoy bold, smoky flavours? A balanced and smooth cup? Or a bright, fruity complexity?
Understanding how roasting affects coffee beans will help you choose the roast level that best suits your taste. Each roast level brings out different flavour characteristics, and the way coffee is processed, brewed, and served can influence how those flavours shine in your cup.
How the Roasting Process Affects Coffee Beans
Coffee beans start as green, dense, and flavourless seeds before roasting transforms them into the aromatic, brown beans we grind and brew. The roasting process changes the coffee’s chemical composition, affecting its flavour, body, acidity, and aroma.
During roasting, heat breaks down sugars, caramelises compounds, and develops the coffee’s flavour profile. Lighter roasts preserve more of the coffee’s natural, origin-specific characteristics, while darker roasts allow the roasting process itself to shape the final flavour.
Roasting also reduces moisture and caffeine content, meaning lighter roasts generally retain slightly more caffeine than darker roasts (though the difference is small).
Now, let’s break down what you can expect from each roast level.
Light Roast: Bright, Fruity, and Complex
Light roast coffee is roasted for the shortest amount of time at lower temperatures. The beans remain light brown with little to no oil on the surface, preserving more of their natural acidity and origin-specific flavours.
Flavour Profile:
- High acidity, which gives coffee a lively and vibrant character
- Pronounced fruit, floral, and citrus notes
- A lighter body with a tea-like texture
- Complex flavour layers that change as the coffee cools
Best For:
If you enjoy bright, nuanced flavours and want to experience the full expression of a coffee’s terroir (where it was grown), a light roast is the best choice. This is especially true for African and Central American coffees, which often have delicate floral and citrus notes.
Medium Roast: Balanced, Sweet, and Smooth
Medium roast coffee is roasted slightly longer, giving the beans a deeper colour and a balanced flavour profile. These roasts retain some of the coffee’s natural characteristics while also introducing caramelisation and sweetness from the roasting process.
Flavour Profile:
- Well-rounded acidity and sweetness
- Hints of caramel, nuts, and mild chocolate
- A smooth, medium body that feels richer than a light roast
- A balance between the coffee’s natural flavours and roast-driven notes
Best For:
If you prefer a balanced cup with rich sweetness but still some bright acidity, a medium roast is ideal. This roast level is a favourite among speciality coffee drinkers because it allows both the bean’s natural origin characteristics and the roasting process to shine.
Dark Roast: Bold, Smoky, and Intense
Dark roast coffee is roasted at high temperatures for the longest time, resulting in deep brown, sometimes almost black beans with an oily surface. These beans take on more of the roasting flavours while losing some of their original fruity or floral complexity.
Flavour Profile:
- Bold, roasty flavours with notes of dark chocolate, caramel, and toasted nuts
- A lower acidity, making for a smoother, less tangy cup
- A heavier body with a slightly smoky or even spicy edge
- A more uniform flavour, with fewer of the distinct origin characteristics found in light roasts
Best For:
If you enjoy bold, rich coffee with a strong, roasted flavour, dark roasts are for you. They’re great for espresso-based drinks because their deep caramelisation helps cut through milk, creating smooth, full-bodied lattes and cappuccinos.
Which Roast Tastes Better?
There’s no single answer—it all depends on what you like.
- If you love bright, fruity, and floral flavours, light roast is your best choice.
- If you prefer a smooth, well-balanced cup, medium roast offers the best of both worlds.
- If you want a bold, strong coffee with roasty, chocolatey notes, dark roast is the way to go.
The best way to find your favourite roast is to experiment! Try different roasts using the same brewing method and see which flavours you enjoy most.
How Brew Method Affects Roast Flavour
Different brew methods highlight different aspects of a roast’s flavour.
- Pour-over (V60, Chemex) brings out the complexity and acidity of light and medium roasts.
- Espresso machines extract the deep caramel and chocolate notes of dark and medium roasts.
- French press enhances the rich, full-bodied qualities of medium and dark roasts.
- AeroPress is great for experimenting, as it can bring out both the bright and bold notes of any roast.
If you want to fully experience the unique characteristics of a roast, grind your coffee fresh and brew it carefully—the right grind size, water temperature, and brew time can make a huge difference in flavour.
Final Thoughts: Choose What You Love
There’s no “best” roast—only the one that tastes best to you. If you prefer something bright and fruity, go for a light roast. If you enjoy smooth caramel and nutty flavours, try a medium roast. And if bold, dark chocolate notes are your thing, a dark roast will hit the spot.
The beauty of coffee is that there’s no wrong answer. Experiment, explore, and most importantly—enjoy every sip.
