Coffee plays a pivotal role in so many people’s morning routines. When thoughtfully sourced and carefully roasted, coffee can be both comforting and invigorating, offering a sensory experience that goes well beyond caffeine alone and even serves as a beneficial wellness essential.
Understanding how roast profiles shape flavour, aroma, and body allows coffee lovers and roasters alike to make more intentional choices about what they choose to drink. In this guide, we break down the fundamentals of roast profiles and explore how the roasting process transforms humble coffee berries into a cup that perfectly suits your taste and lifestyle.
Why Roast Profiles Matter
A roast profile is a set of parameters that define how a batch of coffee beans has been roasted. Coffee flavour comes from its roasting method, determined by time, strength, and included ingredients. Coffee is a versatile medium, so by adjusting these parameters, coffee roasters can play around and create endless combinations of flavour experiences.
This is why most cafés partner with a dedicated coffee roaster like Sunshine Coast Coffee Roastery. By working regularly with a dedicated roaster, café owners can depend on reliable local delivery options and consistent flavour profiles, which their customers will have come to expect every time they order.
Some cafés also roast their own coffee, and you can even do it too, right at home! The roasting process is not entirely complicated, and with a little preparation and insight, you could even make your own unique roast profiles in your own kitchen.
The Stages of Coffee Roasting
A great way to enhance your mornings and save money on coffee is by roasting it yourself! Since everyone has their own coffee preferences, there is no uniform coffee roasting process, but there is, more or less, a set of necessary steps required to roast coffee beans to brew drinkable coffee.
Here are the basic steps to roasting coffee either professionally or at home. Although they have different names, the whole process is considered “roasting”.
Fun fact: Coffee beans are, in fact, roasted and ground berries!
Drying Phase
First, green coffee berries are loaded, or charged, into either a spinning roaster or an oven and heated until they begin to dry out and change colour. This process causes the water pressure in the berries to rise and thus crack, thus roasting the “beans”. Heat intensity, spinning velocity, and time will dictate the colour of the beans and thus the flavour of the roast.
Caramelization Phase
As the beans continue to dry and crack, the sugars begin to break down and caramelise. This process determines much of the coffee’s base sweetness and expression, or body. In general, the faster a coffee proceeds through the caramelisation phase, the more it will tend to express a lighter body and higher sweetness; the slower a coffee proceeds through caramelisation, the more it tends to express a higher body and lower sweetness.
Pro tip: Add different ingredients in this stage to enhance the flavour notes of your roast, such as vanilla bean, cacao, lavender, etc.
Development Phase
Development is the final phase of the roasting process, lasting from first crack to the end of the cycle. The end temperature of the roast will depend on the desired roast degree. To put it in simple terms, this is the phase of a roast during which the lightness or darkness of a roast is finally determined, and the end product is ready for grinding and brewing once cooled.
Factors that Influence Roast Profile Flavour
Whether you’re roasting your coffee at home or through a professional roastery, you ultimately are aiming for a specific kind of flavour. What we taste in a cup of coffee is a complex blend of four aspects of flavour: sweetness, acidity, bitterness, and aroma.
A roast profile is determined by these factors, which can influence the taste of the final product as well as what brewing methods and pairings work best. Here are the main flavour influencers that roasters take into consideration when preparing their roast profiles.
Sweetness
As an organic compound, green coffee contains a number of natural sugars that change throughout the roasting process. As these sugars react to heat, the natural sweetness gives way to more bitter flavours, just like in the production of light and dark caramels. Often, extremely light roasts boast an acidity that can overpower the natural sweetness, whereas very dark roasts do the same but instead with bitterness.
Acidity
Remember, coffee is a fruit! Just as sugars are naturally present in all coffee, so too is acid. Acidity is typically loudest in light-roasted coffee and more muted in darker roasts. Many modern coffee roasters aim to highlight a coffee’s acidity most, as this typically goes hand-in-hand with the distinctiveness of particular types of coffee beans. If you want to avoid high acidity in your roast profile, then opt for a darker roast instead.
Bitterness
Bitterness is an unavoidable factor in any coffee profile. The less sweetness there is in a roast, the more bitter it will naturally taste. Bitterness is usually associated with medium and dark roasts and with particular brewing methods, such as espresso, French presses, and drip coffee. For less bitter roasts, aim for lighter roast profiles.
Aroma
Aroma plays a large role in the taste of a coffee profile, too. The compounds we smell are a complex formula, a fusion of all its essential elements that is difficult to isolate and replicate. That is why it is so difficult to produce synthetically made coffee scents and why the smell of coffee in the morning is such an irresistible everyday comfort.
Craft The Perfect Cup of Coffee with Thoughtful Roasting
Understanding roast profiles is what transforms coffee from a simple beverage into a uniquely crafted experience. With these four factors working together, coffee roasters can create all kinds of combinations and roast profiles, and buyers can make more informed decisions when purchasing coffee at the store or at cafés.
Mastering these variables will allow you to achieve consistency in every cup and tailor flavours that suit your own preferences. Whether you enjoy a coffee that is light and acidic, dark and bitter, or sweet and aromatic, coffee roasting allows caffeine connoisseurs the power to take control of what they pour each morning.
With a little knowledge and curiosity, roast profiles can become less of a mystery and more of a creative skill, empowering you to enjoy coffee that’s truly made your way.
