Embarking on the journey of coffee, from its humble beginnings on a farm to the delightful cup in your hands, is truly a captivating adventure. It’s a journey brimming with intricate details and fascinating processes. By delving into these aspects, you can significantly enrich your coffee selection experience. Take, for example, specialty coffee. It goes through numerous stages that profoundly shape its final flavor. Elements like the soil’s composition, the altitude of the farm, and the transformation process all contribute to the unique profile of each coffee cherry. As a coffee enthusiast, this knowledge can equip you with the ability to decipher label information with greater precision. And who knows? This newfound understanding may just guide you to your ideal coffee companion.

Embarking on the Coffee Journey: It All Starts with Planting

Each country proudly presents its own unique terroir and distinct coffee cultivation methods. The soil’s composition plays a crucial role in determining the quality of the coffee. Similarly, the nearby flora surrounding the plantations contributes significantly to the coffee’s unique profile. Factors such as temperature, rainfall, shade, and altitude are also key players. These elements come together in a harmonious blend, crafting the distinct character of the coffee that you delightfully savor in your cup.

The world of coffee is abuzz with discussions about the countries that cultivate this beloved beverage. It’s a common perception that Ethiopian and Kenyan coffees are renowned for their enchanting floral aromas, while Asian brews are recognized for their hearty body and spicy nuances. Meanwhile, Brazilian coffees are often lauded for their typically smooth and mild characteristics. While these generalizations hold some truth, numerous dedicated farmers are working tirelessly to reveal the intricate and diverse landscape of coffee that goes beyond these broad strokes.

The soil type where coffee is cultivated has a profound influence, albeit its effect can be complex to understand. Regrettably, this crucial detail often gets missed out on packaging labels. You may frequently spot mentions of coffee grown on volcanic soil, but grasping its precise impact can be a bit tricky. However, there’s another tidbit that is consistently shared and, we believe, is much more fascinating – the altitude at which the coffee is grown.

Isn’t it intriguing to discover the significant impact altitude has on coffee cultivation and, in turn, its flavor? Coffee plants nurtured at higher altitudes tend to ripen more slowly. This slower maturation process results in beans that are denser and smaller than their counterparts grown at lower altitudes. As a delightful consequence, the aromatic compounds in these high-altitude coffees are often more concentrated, contributing to their distinct and captivating taste.

The Evolution Continues Uninterrupted

Once the coffee cherries are plucked from their branches, they embark on a fascinating journey of transformation, ultimately becoming the coffee we know and cherish. A key stage in this process is fermentation, often regarded as one of the most influential steps in defining the coffee’s flavor. However, the extent of its direct impact is a subject of ongoing discussion. Some experts suggest that “fermentation primarily facilitates the pulping process by removing the mucilage that surrounds the parchment”. This implies that while fermentation may not directly shape the coffee’s final taste, any errors during this stage could potentially spoil the entire batch. This captivating viewpoint can be explored further in issue 163 of the 1935 Journal d’agriculture traditionnelle et de botanique appliquée.

Isn’t it fascinating? Recent research has uncovered that a humble coffee bean contains around 30 aromatic markers before it undergoes fermentation. But here’s the kicker – this number dramatically soars to a staggering 3,000 after the process! This pivotal stage plays a key role in amplifying the delightful aromas that make your coffee so irresistible.

At this moment, we can distinguish four main techniques of fermentation.

“Natural” or the dry method :

Exploring the “Natural” or Dry Method

This method involves drying whole coffee cherries in the sun or in mechanical dryers. Producers then sort and dry the beans. This method produces more intense aromas, notably of red or exotic fruits. Historically, the dry method originated in Ethiopia, particularly in countries where access to water can be complex and expensive.

Let’s explore the dry process, which is conveniently divided into four simple and straightforward steps:

  • Cherries are dried in the sun
  • The result is a brown “café coque”. The cherries are dry when they make a characteristic dry noise as they rub against each other.
  • Hull coffee” is husked in a machine
  • Obtaining green coffee the “natural” way
“Washed or wet method :

Exploring the Washed or Wet Method

History This method originated in Jamaica, a country where humidity levels are often very high, and where air-drying is therefore complex. In this method, the beans are washed with water for several hours before being dried. It is often said that washed coffees are more acidic. This method is reputed to bring out the coffee’s intrinsic characteristics to the full. The taste is often more delicate.

After the parchment layer is skillfully removed, we’re left with a product fondly referred to as “washed” green coffee.

The aim of this method is to retain the aromatic benefits of wet fermentation. At the same time, it takes an ecological view of water consumption. Indeed, we know that the wet method is simpler to implement than the washed method, and seems to be more respectful of the fruit. The cherries are pulped, but instead of being fermented in vats and then washed, the beans are dried immediately.

The honey process:

Unveiling the Sweet Journey: The Honey Processing Method

Here, the aim is not to avoid the shortcomings of wet or dry methods, but rather to exploit them to improve coffee quality. It’s a clever fusion of the two approaches!

More precisely, before and after pulping the cherry, several variables come into play: the thickness of the mucilage, the type of drying – whether sun or shade – the amount of oxygen, the ripeness and variety of the cherry, and so on.

All these subtleties have distinct names such as black, red, yellow or white honey.

This method often results in floral, sweet and acidic coffees, ideal for mild extractions. On the technical side, the cherries are sorted in a flotation tank, then the fruit is pulped using a machine before being exposed to the sun for drying.

An interesting feature that gives honey its character: once the cherry is pulped, the remaining mucilage – the pulp – around the coffee bean caramelizes and takes on an amber hue.

We’ve only just scratched the surface with four fermentation processes, but there’s an entire universe of innovative methods out there, ripe for discovery. These range from intriguing techniques like anaerobic and carbonic maceration to thermal shock and infusion with fresh fruit, and even extend to lactic acid fermentation and beyond. The ultimate aim? To create coffees that boast unique and unconventional flavors. These flavors are awakened by microorganisms, which may either naturally exist in the fruit or be intentionally introduced. The resulting aromatic notes can be strikingly unique, promising a tasting experience that’s nothing less than extraordinary.
