Light roasts: exploring unsuspected complexity

published on February 11, 2025 — by Marc-Alexandre Emond-Boisjoly — 10 mins of reading —


There's a widespread myth surrounding light-roast coffees: they lack taste and intensity. In reality, these coffees, often described as "pale" or "light", offer a unique taste journey. Their finesse is revealed in a rich, lively and complex aromatic palette, which leaves plenty of room for the subtlety of their terroir of origin. At 94 Celcius, in Montreal, we see light roasting as a veritable playground, where innovation, precision and excellence become the epicenter of sensory exploration.

In this article, we invite you to discover why these coffees, sometimes overlooked for fear of too pronounced acidity or too discreet sweetness, are in fact an ode to contemplation and balance. We'll also talk about the possible transition if you're used to darker roasts. Prepare to revise your certainties and broaden your horizons: coffee, like any rich universe, never ceases to surprise.

Breaking the myth of "lightness

The first misconception surrounding light roasting is that it lacks character. The reason? Many people associate the strength of a coffee with its bitterness. But bitterness is only one component of the taste profile. Light coffees, devoid of the carbonation often found in darker roasts, do not rely on bitterness to build their identity. Instead, they are distinguished by a delicate acidity, sometimes fruity or floral, that has nothing to do with the overly pronounced "citrus" acidity we often imagine.

This acidity brings a liveliness and freshness that give the impression of plunging into the heart of the terroir, as if you were walking through a coffee plantation in the early hours of the morning. It's an immersion in the very origin of the bean, in its history and in the alchemy of the land where it was born. When you open yourself up to this approach, tasting becomes an invitation to contemplation, to the discovery of nuances of aroma that reveal themselves in harmony.

Between subtlety and complexity: the magic of light roasting

Grains reveal their terroir

A coffee bean is a reflection of its terroir and the work of the men and women who have grown it. Altitude, botanical variety, soil quality and processing method (washed, natural, honey, etc.) all influence the final taste. Light roasting preserves these characteristics. Where dark roasting tends to unify flavors under a more toasty color, light roasting preserves the aromatic structure that makes each origin unique.

Think of the bean as a passport to its homeland. Instead of layers of toast, light roasting sends us straight to the heart of the plantations: fruity, floral notes, sweet spices, sometimes a touch of subtle caramel. Coffee becomes a unique field of exploration for those who love to travel through their cup.

Less bitterness, more vivacity

In the popular imagination, bitterness is often associated with "full-bodied" coffee. However, full-bodied does not necessarily mean "tastier". Rather, it means that the bean's natural sugars have been caramelized (or even burnt) to a greater extent during roasting. A darker bean will have more pronounced roasted flavors, but the aromatic spectrum of the terroir may take a back seat.

Light roasts, on the other hand, leave plenty of room for noble acidity: a slight hint of citrus, aromas of red berries, sometimes orange blossom, depending on origin. This acidity, though present, blends harmoniously with the rest of the flavors. It's not the sourness we fear, but rather the liveliness that brings out the cup's finesse. With a light coffee, we enter a sensory universe where everything is a question of balance and precision.

Lighter but not weaker bodies

It's true that a light-roasted coffee will generally have a less dense body in the mouth than a very dark coffee. But less density doesn't mean less pleasure. On the contrary, you'll enjoy a silky, sometimes delicate sensation that enhances the aromatic nuances. With a good extraction ratio, this lightness allows you to distinguish each flavor, as if you were browsing a detailed map of aromas.

Where does the notion of acidity come from, and why isn't it "negative"?

The term "acidity" can be frightening. It sometimes evokes a sensation of aggressiveness on the tongue or palate. However, there are different forms of acidity in gastronomy. We appreciate the juice of a fresh lemon in a recipe, or cider vinegar in a salad. So why not the acidity of a coffee?

In fact, in a light-roasted specialty coffee, acidity is closer to freshness. It reveals the underlying flavours. Without acidity, a coffee can seem bland, without relief. With controlled acidity, we discover a festival of aromas that dance on the tongue: notes of cherry, grapefruit, peach or jasmine flower, depending on the origin. It's this invigorating dimension that makes all the difference, and gives you that sensation of purity when you taste a light coffee.

Quality control through light roasting

To ensure the quality of a new batch of coffee, clear roasting is the preferred method used by specialist micro roasters. Why is this? Because there's no room for cheating. Any defects in a bean (over-fermentation, immature beans, drying problems) are immediately apparent in the mouth. Conversely, when the beans are of good quality, light roasting gives way to their true potential.

The quality control team at 94 Celcius carries out a number of tests to ensure that our products meet the highest quality standards. cuppingThis is usually done with a filter grind, infused for four minutes. It's a strict protocol. In the world of coffee, there's a universal language for describing, assessing and rating the cup. Far from being overly technical, it helps us to understand the personality of each coffee and to guide it towards its ideal roasting profile.

Making the transition to light roasting: one step at a time

Are you a fan of dark coffees and afraid of taking the plunge into the unknown? You don't have to dive straight into an ultra-light coffee. As with any journey, the important thing is to take it one step at a time, so as to tame the new flavors.

Moving on to medium-bodied

A clever way to explore the light coffee route is to start with a medium-bodied coffee. It already offers less bitterness and a little more acidity than its dark counterpart, while retaining a certain familiar roundness. You'll be able to detect those little differences that make up the identity of a less roasted coffee: a slight floral note, a fruity sweetness, more discreet spices.

Diversifying origins

Each terroir has its own history, climate and botanical varieties. A washed Ethiopian coffee will tend to present floral and tropical fruit notes, while a washed Colombian coffee will bring out a sharper, often citrusy acidity, accompanied by delicate caramel notes. By diversifying your origins, you can broaden your palette of tastes and treat yourself to a sensory journey that's both exciting and instructive.

Choosing the right tasting moment

When tasting an unfamiliar coffee, choose a time of day when you're awake and ready for discovery: late morning, early afternoon. Your senses, less saturated, will be more inclined to perceive the subtleties of the cup. Avoid trying a new coffee in the morning rush if you need a caffeine fix to start the day.

Grind coffee just before brewing

Beyond the choice of roast, the freshness of the grind is essential. Coffee aromas are highly volatile. After just a few minutes, they start to evaporate. To be on the safe side, choose a coffee bean and grind it just before extraction. You'll be amazed at the difference in aroma and roundness in your cup.

Conclusion: an invitation to discover

Light roast coffees are not just for the elite. They're for the curious in search of new sensations, for those who want to go beyond bitterness and discover the infinite palette offered by the bean. To open up to these more delicate coffees is to set out on the conquest of a wider, more nuanced universe.
