History of Coffee Cultivation
Coffee was introduced to Ceylon by the Dutch in the 1700s and expanded under British colonial rule in the 1800s. By the 1860s, Ceylon was one of the world's largest coffee producers. However, coffee leaf rust (Hemileia vastatrix), first identified in 1869, destroyed an estimated 500 million coffee trees over two decades, ending Ceylon's coffee industry. Plantation owners switched to tea, which made Ceylon (now Sri Lanka) famous for tea rather than coffee. In recent years, small-scale specialty coffee production has resumed.

Coffea Arabica: The Specialty Coffee Species Explained
Arabica coffee (Coffea arabica) is a species of coffee plant native to the highland forests of Ethiopia and South Sudan. It is the most widely cultivated coffee species worldwide, accounting for approximately 60 to 70 percent of global coffee production. Arabica is prized for its complex flavor, refined acidity, and aromatic diversity, producing notes ranging from floral and citrus to chocolate and caramel depending on origin, variety, and processing.
Origins & GeographyCoffea Robusta: The Hard-Body Coffee Species Explained
Robusta coffee (Coffea canephora) is the second most cultivated coffee species after Arabica, accounting for approximately 30 to 40 percent of global coffee production. Native to sub-Saharan Africa, Robusta is hardier, more disease resistant, and grows at lower elevations than Arabica. It contains roughly twice the caffeine of Arabica and produces a heavier body, lower acidity, and more bitter cup profile.
Coffee ScienceCoffee Leaf Rust
Hemileia vastatrix belongs to the order Pucciniales and is an obligate biotrophic fungus, meaning it requires living host tissue to survive. The infection cycle begins when urediniospores are deposited on the abaxial (underside) surface of the coffee leaf, typically via wind or rain splash. Germination occurs only in the presence of free water—such as dew or rainfall—within a temperature range of 15°C to 28°C. Upon germination, the fungus enters the leaf through the stomata and establishes a mycelium that colonizes the internal tissue. The visual manifestation of the disease begins as small, chlorotic spots that expand into characteristic orange, powdery pustules. These pustules contain thousands of spores capable of further infection. The physiological impact includes a rapid reduction in photosynthetic capacity and the eventual abscission of the leaf. Severe cases lead to 'dieback,' where the plant's branches wither due to carbohydrate depletion, often resulting in the death of the tree or a total loss of the following year's crop.
Coffee CultureCortado
<h2>Technical Specification and Variations</h2><p>In the context of the Specialty Coffee Association (SCA) brewing standards, the cortado sits between the macchiato and the flat white in terms of milk volume and dilution. While the macchiato uses a 1:0.5 ratio of espresso to foam, the cortado’s 1:1 ratio provides enough thermal mass to stabilize the beverage temperature without over-diluting the Total Dissolved Solids (TDS). In regions such as Cuba, a variation known as the 'cortadito' involves the addition of pre-sweetened espresso (espuma) or condensed milk, though the traditional Spanish preparation remains unsweetened. The beverage chemistry relies on the interaction between milk lipids and the espresso’s crema; the fats in the milk bind to the bitter alkaloids in the coffee, effectively 'cutting' the perceived bitterness while enhancing the tactile weight (mouthfeel) of the drink.</p><table><thead><tr><th>Feature</th><th>Cortado</th><th>Macchiato</th><th>Flat White</th></tr></thead><tbody><tr><td>Ratio (Coffee:Milk)</td><td>1:1</td><td>1:0.5 (Foam)</td><td>1:2 or 1:3</td></tr><tr><td>Total Volume</td><td>120ml - 135ml</td><td>60ml - 90ml</td><td>160ml - 200ml</td></tr><tr><td>Vessel</td><td>Glass (Gibraltar)</td><td>Ceramic Demi-tasse</td><td>Ceramic Cup</td></tr><tr><td>Milk Texture</td><td>Micro-foam (0.5cm)</td><td>Dry Foam</td><td>Micro-foam (1cm)</td></tr><tr><td>Temperature</td><td>55°C - 60°C</td><td>60°C - 65°C</td><td>65°C - 70°C</td></tr></tbody></table>
Coffee ScienceExtraction
Extraction is the process of dissolving soluble compounds from ground coffee into water, producing the beverage we know as coffee. During extraction, water pulls acids, sugars, lipids, carbohydrates, and melanoidins from the coffee grounds in a sequence that shapes flavor, body, and aroma.
Coffee ScienceQuakers
<h2>Summary of Quaker Identification and Prevention</h2><ul><li><strong>Biochemical Profile:</strong> Characterized by a lack of sucrose, preventing caramelization during the roasting process.</li><li><strong>Visual Markers:</strong> Identified after roasting by a pale, yellowish-tan color compared to the dark brown of healthy seeds.</li><li><strong>SCA Standard:</strong> Zero tolerance for quakers in 100g of Grade 1 Specialty Coffee.</li><li><strong>Prevention:</strong> Managed through selective picking of deep-red cherries and rigorous flotation during wet processing to remove low-density seeds.</li></ul>
RoastingRoast Profile
A comprehensive roast profile serves as a chronological data set representing the thermal energy transfer from the roasting environment to the endosperm of the coffee seed. Utilizing digital logging software such as Cropster or Artisan, roasters track the Bean Temperature (BT) and Environmental Temperature (ET) at sampling rates of 1 Hz or higher. Key milestones include the Charge Temperature—typically ranging from 180°C to 220°C—and the Turning Point, where thermal equilibrium is established between the beans and the drum. The profile meticulously maps the endothermic drying phase and the transition to the Maillard stage, where amino acids and reducing sugars synthesize melanoidins. Precise modulation of the development time ratio (DTR), often targeted between 15% and 25% of the total roast duration, dictates the degradation of chlorogenic acids and the caramelization of sucrose, fundamentally altering the solubility and sensory attributes of the final product.
RoastingSecond Crack
Second crack is a softer, faster, and less audible cracking sound that occurs during coffee roasting at approximately 224 to 232 degrees Celsius (435 to 450 degrees Fahrenheit). It occurs after first crack and signals the transition from medium to dark roast. During second crack, the cell structure of the bean begins to fracture as oils migrate to the surface, producing a darker, oilier, and more bitter cup.
Coffee CultureSpecialty Coffee
The classification process necessitates precise environment control. During the grading phase, the coffee is roasted within 24 hours of cupping and allowed to rest for at least eight hours. The roast level must fall within the light to medium range, specifically between 55 and 65 on the Agtron scale. Cupping involves a standard ratio of 8.25 grams of coffee per 150 milliliters of water, with water temperatures maintained between 92.2°C and 94.4°C (198°F to 202°F). This protocol ensures that the inherent characteristics of the bean—such as the phosphoric acidity typical of Kenyan origins or the stone fruit notes of Colombian Caturra—are evaluated without the interference of roast-induced flavors.

Typica Coffee Variety
Typica is the foundational arabica variety from which nearly all cultivated coffee descends. Originating in Ethiopia and Yemen, then carried to Java and the Americas, its tall trees and elongated cherries produce a clean, sweet, delicately floral cup that defined specialty coffee's earliest standards.
Catimor Coffee Variety
Catimor is a high-yielding arabica-robusta hybrid bred for disease resistance and altitude adaptability. While often dismissed for quality, well-managed Catimor lots from high-elevation farms can produce bold, full-bodied cups with surprising complexity.
Bourbon Coffee Variety
Bourbon is one of the two foundational arabica varieties, named after Réunion Island (formerly Île Bourbon). It produces higher yields and a sweeter, more complex cup than Typica, with distinctive notes of chocolate, caramel, and red fruit that set the standard for specialty coffee quality.
