What does roasting do to taste?

When people first dive into the world of specialty coffee, they often look at the machine, the coffee grinder, or the coffee beans themselves. However, an important aspect that is regularly underestimated is coffee roasting.

The way coffee is roasted has an enormous impact on what you ultimately taste in your cup. Sometimes even more than people initially expect.


Coffee actually starts green

Before coffee gets that recognizable aroma and taste, coffee beans are light green in color. They are very hard, odorless, and totally unlike what ultimately ends up in your cup. Some even say green beans smell like grass.

It is only during roasting that the aromas and flavors we associate with coffee emerge. Sugars caramelize, acids change, and all sorts of flavor compounds develop under the influence of the roaster's heat.

Therefore, the roaster has a huge influence on the end result.

A light roast often brings out very different characteristics of the coffee beans than a dark roast. And that's where a taste difference arises.


Light roast: more freshness and detail

Light roasted coffee retains much of the bean's original character. A coffee bean grows as a berry on a bush, and if you light roast those beans, you can still taste a bit of the berry. This often results in more fresh, sweet, and pronounced flavors.

Some coffees thereby acquire an almost wine-like or tea-like quality. Think of citrus, red fruit, or floral notes. For people discovering specialty coffee, this can be surprising because it tastes totally different from classic dark, almost bitter, espresso.

Light roasting often better reveals where a coffee comes from. An Ethiopian coffee can therefore taste very fruity and lively, while a Brazilian bean tends more towards nuts and chocolate.

However, light roasting usually requires a bit more precision when brewing espresso. The extraction needs to be just right, otherwise, coffee can quickly taste sour or sharp.

Medium roast: balance and accessibility

Medium roast combines two worlds. The flavor nuances in a milder form than with lighter roasts, and the fullness and body found in darker roasts.

If you don't like citrus notes or tea-like coffees, a medium roast is something to try. These are often the coffees where people recognize flavors like milk chocolate, chocolate, caramel, spices, or nuts. Without becoming extremely bitter or extremely fresh.

For a budding home barista, a medium roast often works very well. Medium roast is usually more forgiving and easier to adjust than very light roasts.

Or if you just want to enjoy a cup of coffee that's a little different but not too crazy.

Dark roast: powerful and classic

For dark roasts, the coffee is roasted for a longer period. This causes many fresh acids to recede into the background, and deeper, heavier flavors emerge.

This creates that typical classic espresso that many people know from Italian coffee: powerful, full-bodied, and more bitter. At FREKKO, we don't roast our dark roasts to be bitter like the Italians. We stop a bit earlier to retain the mild, full flavor without bitterness.

Some people absolutely love this robust style. Often, people choose to combine a dark roast with milk-based drinks like cappuccinos or flat whites, because the coffee flavor beautifully comes through the milk.

At the same time, too dark a roast can cause subtle flavor nuances to disappear. Then you mainly taste the roasting process itself instead of the original bean.

    Dark doesn't automatically mean better

    A common misconception is that dark coffee is "stronger" or "higher quality."

    That's not true.

    Dark roasts often taste more intense and bitter, but that says little about the quality of the coffee itself. In fact, within specialty coffee, much attention is paid to roasting that allows the characteristics of the bean to remain visible. These characteristics of different coffees are precisely what makes them so interesting to discover.

    Likewise, fresh flavors do not automatically mean that coffee is bad or sour. A well-prepared light espresso can actually taste pleasantly complex and interesting. So much to discover!


    Why taste preference is so personal

    Ultimately, coffee is a matter of taste. And there's no arguing about taste.

    Some seek a heavy espresso with a full body and dark chocolate notes. Others prefer a fruity, fresh espresso where you discover different layers.

    Neither is wrong.

    What we do notice at FREKKO is that many people slowly start to appreciate other flavors as they experiment more with beans and roasting. Someone who previously only drank dark espresso sometimes suddenly discovers how interesting a medium roast can be. And someone who normally only drinks light roasts also finds a detour to a dark roast cappuccino very enjoyable.

    Roasting and your equipment

    Your equipment also plays a role.

    Light roasted beans are often harder and demand more from your coffee grinder and machine. In terms of sturdiness, but also in terms of adjusting nuances, a coffee grinder with adjustable grind size is a must. A stable temperature and consistent grind also become more important.

    Dark roasts are usually easier to extract and therefore often more accessible for aspiring home baristas. Dark roasts from the supermarket often have an oily layer, and you don't want to see that oily layer in your coffee grinder or espresso machine. That's why you'll never see this oily layer at FREKKO.

    That's why good espresso is never just about the bean, but always about the whole picture. And the coffee grinder is the most important factor here.


    Our tip at FREKKO

    Try drinking different roasts side by side. That is by far the fastest way to discover what you like.

    Because ultimately, coffee is not about complicated terms or trends, but about taste experience. And roasting plays a much bigger role in that than most people initially think.
