Balance

Acidity

In coffee tasting, acidity refers to the bright, vibrant, and often fruity quality that gives coffee its liveliness and structure. Unlike the negative connotation of acidity in everyday language, coffee acidity is a desirable characteristic when balanced. It is perceived as a pleasant tartness or brightness on the palate, similar to the acidity in wine or fruit.

Americano Ratio Guide

An Americano dilutes concentrated double espresso with hot water, yielding a beverage with filter-like volume but espresso flavor complexity. This guide explores dilution formulas, water temperatures, and sequence differences between Americano and Long Black.

Body

Body, also called mouthfeel, refers to the physical weight, texture, and viscosity of coffee as it is perceived in the mouth. It is a tactile sensation rather than a taste, ranging from thin and tea-like to thick and syrupy. Body is influenced by brewing method, coffee oils, suspended solids, roast level, and the variety and origin of the coffee.

Castillo Coffee Variety

Castillo is Colombia's most widely planted variety, bred by Cenicafé as a disease-resistant descendant of Catimor. Successive selections improved cup quality significantly, and well-grown Castillo from high-altitude farms in Caldas and Nariño delivers sweet, balanced cups that far exceed its reputation.

Catuai Coffee Variety

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.

Clean Cup

A clean cup is coffee free from defects, off-flavors, or taints. Cleanliness is a scored attribute on the SCA cupping form. A clean cup has no negative flavors such as fermentation, mustiness, staleness, or earthy notes.

Cupping

Cupping is the standardized professional method for evaluating coffee quality and flavor. Developed by the specialty coffee industry, cupping involves smelling and tasting coffee prepared through a controlled immersion method, then scoring specific attributes including fragrance, aroma, flavor, aftertaste, acidity, body, balance, uniformity, clean cup, sweetness, and overall impression.

Comparison

Espresso Vs Drip Coffee

Espresso and drip coffee represent extreme ends of the coffee concentration spectrum. Espresso forces water through tightly compacted fine coffee grounds at 9 bars of pressure, creating a dense emulsified beverage topped with golden crema. Drip coffee uses gentle gravity flow through medium grounds, yielding a clean, lower-concentration beverage designed for sipping.

Ethiopian Landrace Coffee

Ethiopian landrace varieties are the wild and semi-wild arabicas of Guji, Yirgacheffe, and Sidama, each region hosting genetically distinct heirloom populations. This unmatched genetic diversity produces the floral, citrus, and berry-dominant cups that define Ethiopian specialty coffee.

Sudan 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.

Sweetness

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.

Tabi 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.
