Catuai is a compact hybrid of Mundo Novo and Caturra bred in Campinas, Brazil. Its small stature enables high-density planting and easier harvesting, while its cup retains a clean, bright acidity with sweet citrus notes that perform well across Central and South American farms.
Why It Matters
A common misconception is that Catuai is strictly a 'workhorse' variety intended for low-grade commercial blends due to its high yield [6][9]. However, when grown at high altitudes and processed with care, it frequently achieves specialty scores above 85 points [5][10]. Another misconception involves its physical vigor; while the plant is structurally robust against wind and rain, it is highly susceptible to major diseases like coffee leaf rust and coffee berry disease [2][4]. Additionally, while often associated with Central America, it is a Brazilian-developed variety that only expanded internationally decades after its creation [1][2].
Frequently Asked Questions
What is Catuai coffee?
Catuai is a high-yielding Brazilian hybrid variety created by crossing Mundo Novo and Caturra, available in Red and Yellow cherry variations.
Why is Catuai resilient against bad weather?
Catuai cherries adhere firmly to the branches, preventing premature fruit drop during heavy rainstorms or strong mountain winds.
What flavor notes are typical of Catuai?
Catuai offers a classic chocolate and nutty profile with smooth caramel sweetness, medium body, and balanced citric acidity.

Altitude
Altitude is the elevation at which coffee is grown, measured in meters above sea level. Higher altitude generally produces denser, more complex, and more acidic coffee. Arabica is typically grown at 800 to 2,000 meters, while Robusta at 0 to 800 meters.
Sensory & TastingBalance
Balance in coffee is the harmonious integration of all flavor attributes (acidity, body, sweetness, bitterness, aroma) so that no single attribute dominates. Balance is a key scoring category on the SCA cupping form.
Equipment & ToolsBurr Grinder
In the context of specialty coffee, the burr grinder is the foundational instrument for extraction control. Its ability to produce a specific, repeatable particle size distribution (PSD) allows the barista to manipulate the surface area available for solvent interaction. By shifting the burrs, one controls the rate at which organic acids, sugars, and oils are liberated from the cellulose matrix of the roasted bean. Technically, the mill operates via shear and compression forces. Flat burrs, typically ranging from 64mm to 98mm in diameter, produce a unimodal distribution ideal for high-clarity extractions. Conical burrs typically operate at lower rotational speeds of 400 to 600 RPM, minimizing thermal transfer and static build-up. Most commercial burrs are constructed from case-hardened steel, stainless steel, or ceramic materials like alumina, with high-end models featuring titanium or Red Speed coatings to reduce friction and extend the lifespan of the cutting edges beyond 500 kilograms of throughput.
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 ScienceMicro-lot
A micro-lot represents a distinct, traceable quantity of coffee, typically limited to a volume between 1 and 40 bags of 60 kilograms. Unlike regional blends, micro-lots originate from a single harvest period, a specific botanical variety, or a designated plot of land—often referred to as a 'tablón' in Latin American estates. Production requires rigorous physical separation during the picking, pulping, and drying phases to preserve unique sensory profiles. These lots frequently undergo experimental processing, such as carbonic maceration or controlled fermentation with specific yeast strains like Saccharomyces cerevisiae. To qualify as a micro-lot, a coffee usually commands a cupping score of 87 points or higher on the Specialty Coffee Association (SCA) scale, reflecting exceptional clarity and complexity in flavor. The categorization enables the identification of specific terroir influences, where soil composition, shade canopy density, and localized microclimates (mesoclimates) converge to produce a profile that is unrepeatable in larger, aggregated lots.
Varietals & CultivarsSan Ramon Coffee Variety
San Ramon is a dwarf mutation of Typica discovered in Costa Rica that resists wind damage and produces a clean, sweet cup.
Varietals & CultivarsSl28 Coffee Variety
SL28 is the legendary Kenyan arabica selection from Ruiru, bred by Scott Laboratories for drought resistance and cup quality. It produces the archetypal Kenyan cup: explosive blackcurrant, citrus brightness, and a wine-like complexity that makes it the benchmark for specialty coffee worldwide.
Varietals & CultivarsSl34 Coffee Variety
SL34 is a Kenyan selection from Kabete, often confused with SL28 but descended from a different Bourbon lineage. It thrives at slightly lower altitudes and produces a fuller-bodied cup than SL28, with the same signature Kenyan blackcurrant acidity but a heavier, more syrupy mouthfeel.
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.
Varietals & CultivarsSudan Rume Coffee Variety
Sudan Rume is a wild arabica from the Boma Plateau in South Sudan, prized by competition baristas for its explosive tropical fruit and floral aromatics. Nearly extinct in cultivation, it survives in research plots and elite farm lots.
Sensory & TastingSweetness
In physiological terms, sweetness in Coffea arabica is a multi-modal sensory response triggered by a complex matrix of chemical constituents. While green Arabica beans contain between 6% and 9% sucrose by dry weight—compared to 3% to 7% in Coffea canephora —the roasting process degrades approximately 97% to 99% of these sugars. The resulting sweetness perceived by the taster is a product of caramelization and the Maillard reaction. Specifically, the thermal degradation of sucrose yields glucose and fructose, which further react with amino acids to form furans, such as 4-hydroxy-2,5-dimethyl-3(2H)-furanone, contributing to caramel-like aromatics. The SCA Cupping Protocol utilizes a binary score for sweetness; each of the five cups must exhibit a clean, sweet character to receive a 2-point credit, totaling 10 points for a perfect set. This attribute is fundamentally linked to the metabolic health of the tree and precise harvest timing, where cherries typically reach 18% to 22% soluble solids on the Brix scale before picking.
Varietals & CultivarsTabi Coffee Variety
Tabi is a Colombian cross of Typica, Bourbon, and Hibrido de Timor bred by Cenicafé for disease resistance without sacrificing cup quality. It delivers the clean sweetness of its Bourbon parentage with the resilience coffee farmers need at high altitudes.
Origins & GeographyTerroir
Terroir is the set of environmental factors that give coffee its unique character, including soil composition, altitude, climate, rainfall, microclimate, and topography. Borrowed from winemaking, the concept of terroir explains why coffees from different regions taste distinctly different.
Varietals & CultivarsTypica 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.
Varietals & CultivarsVenecia Coffee Variety
Venecia is a compact Costa Rican variety bred by ICAFE from Sudan Rume and T5295 lines. Its small stature allows dense planting, and its clean, sweet cup profile makes it a quietly reliable performer in Central American specialty coffee.
Varietals & CultivarsVilla Sarchi Coffee Variety
Villa Sarchi is a natural dwarf mutation of Bourbon discovered in Alajuela, Costa Rica. Its compact size suits high-density planting, and its cup retains classic Bourbon character: bright acidity, sweet caramel notes, and a clean finish.
Brewing MethodsWater Temperature
Effective temperature management must account for 'slurry temperature'—the actual temperature of the coffee-water mixture—which typically measures 2°C to 5°C lower than the strike water in the kettle. This thermal loss is a result of the heat capacity of the brewing vessel and the dry coffee grounds. The Arrhenius equation provides a framework for understanding how the rate of extraction increases exponentially with temperature. Specifically, the solubility of caffeine and chlorogenic acids increases linearly with thermal energy, whereas the extraction of lipids and certain aromatic oils requires reaching specific thermal thresholds to overcome surface tension within the coffee grounds' porous structure.
