The coffee world is far more diverse than one might imagine. From a biological perspective, coffee is mainly divided into three major categories: Arabica, Robusta, and Liberica, with the first two accounting for the vast majority of global production. Arabica is known for its balanced flavor and elegant aroma, and is often used for single-origin and specialty coffee; Robusta, with its strong acidity and rich body, is an important ingredient in espresso blends and instant coffee. Beneath this, varieties such as Typica, Bourbon, Caturra, and Geisha each have their own characteristics, with flavors ranging from nutty chocolate to floral and fruity notes. In addition, green bean processing methods such as natural, washed, honey, and wet-hulled also profoundly affect the final acidity, sweetness, and body of a cup of coffee. This article will systematically sort out the origins, characteristics, and flavor expressions of the world's major coffee varieties, helping coffee enthusiasts build a complete framework of variety knowledge.

In the small town of San Agustín in Colombia's Huila region, there is a national archaeological park designated as a UNESCO World Heritage Site. This place is not only home to Colombia's earliest human settlement, but also produces one of the world's rarest coffees: Pink Bourbon. Pink Bourbon is a natural hybrid of Yellow Bourbon and Red Bourbon, a rare variety resulting from recessive gene expression, difficult to cultivate with extremely low yields. The green bean buying team at Front Street Coffee traveled personally to Finca El Diviso to select this micro-lot washed Pink Bourbon, which presents sweet orange, sugarcane sweetness, and a pleasant juicy mouthfeel. This article will guide you through the genetic secrets of Pink Bourbon, its cultivation challenges, and the story and flavor profile behind this coffee. [more…]

Pacamara is a hybrid variety born in 1958 at the Salvadoran Coffee Research Institute, created by crossing the Bourbon variant Pacas with the Typica variant Maragogipe (Elephant Bean). It inherited the large-bean genes of the Elephant Bean, but because its beans were too large, green bean processing became difficult and yields were low, leaving it dormant for nearly half a century. It was not until 2007 that Pacamara won dual championships at the Cup of Excellence in Guatemala and Honduras, and swept the top three places in El Salvador, defeating many Geisha coffees in one stroke, and has since been hailed as the "Geisha rival." This article will guide you through Pacamara's complex lineage, processing challenges, and how it rose to the specialty coffee stage with its rich and varied flavors. [more…]

Coffee varieties continue to evolve through transplantation, mutation, and hybridization, and many of the cultivated varieties on the market today can be traced back to the two major systems of Typica and Bourbon.
