As the birthplace of Arabica coffee, the forests of southwestern Ethiopia nurture countless coffee varieties, which gives the local coffee a unique flavor that is hard to replicate. Because the varieties are extremely diverse, it is difficult for the government to name them one by one, so they are mostly referred to collectively as "heirloom varieties." On this basis, regional varieties and numbered lines beginning with 74 and 75 have also emerged. The grading of Ethiopian coffee beans is based on the number of defective beans, with five grades from G1 to G5, among which G1 and G2 are the highest quality. This time, Front Street Coffee uses washed Yirgacheffe G2 as the representative everyday coffee of the Ethiopian region, presenting the classic flavor of intertwined citrus, white flowers, honey, and tea-like notes, and also includes pour-over suggestions and bean-resting instructions to help coffee lovers gain a more complete understanding of the charm of Ethiopian coffee.

Friends who frequently buy Ethiopian coffee beans are certainly familiar with the variety label "Heirloom," usually translated into Chinese as "native species" or "heirloom." But in the past two or three years, another term has quietly appeared on the packaging of some Ethiopian beans—"Landrace." What exactly is the relationship between it and Heirloom? Are they different names for the same thing, or two completely different concepts? In this article, Front Street will take a careful look at the origins and evolution of Landrace local varieties, starting from Ethiopia's garden planting system, sorting out the mixed-harvest nature of Heirloom, then moving on to JARC's work in identifying local varieties, and why more and more international green bean merchants have begun to purchase these varieties with distinctive regional characteristics separately. At the end, we also include information on the Kaffa Forest lot currently sold by Front Street for everyone's reference and comparison. [more…]

In the global coffee-growing landscape, origins such as Brazil, Colombia, and Indonesia each have their own renown, while botanically coffee belongs to the Rubiaceae family under the genus Coffea, with over a hundred known species, though commercial cultivation is mainly concentrated in three varieties: Arabica, Robusta, and Liberica. Arabica is known for its elegant flavors and rich aromas, accounting for more than seventy percent of global production, and is often used for single-origin and specialty coffee; Robusta, on the other hand, is heat-tolerant, high-yielding, and highly stress-resistant, and is mostly used for instant coffee and espresso blends. This article systematically reviews the advantages and disadvantages of these two major varieties, the origins and flavor characteristics of common Arabica sub-varieties such as Typica, Bourbon, Catimor, and Maragogype, and introduces the Castillo variety bred from a cross between Arabica and Robusta, while also sharing related product experiences from Front Street Coffee in stores and during cupping.

Coffee, as a plant of the Rubiaceae family, has over a hundred known species, but only three cultivated varieties are actually used for drinking: Arabica, Robusta, and Liberica. Among them, Arabica occupies about seventy percent of global production with its exceptional flavor and aroma, making it the top choice for single-origin and specialty coffee. From Ethiopia's native Typica and Bourbon to the Geisha that has swept the market today, Arabica subspecies are rich and diverse, each with its own characteristics. At the same time, origins such as Brazil, Colombia, Panama, Guatemala, Costa Rica, Jamaica, Ethiopia, Kenya, and Indonesia, by virtue of their unique terroir and processing methods, shape distinctly different coffee flavors. Front Street Coffee offers more than 50 different regional coffee beans in its stores, meeting diverse taste needs. This article will systematically sort out coffee variety classification, the advantages and disadvantages of Arabica, and representative global origins, taking you to gain a deeper understanding of the rich landscape of the coffee world.

Caturra and Catuai are two coffee varieties that appear with extremely high frequency in the coffee world, and they are not hard to find whether on large estates or in small producing regions. Nearly one-third of the products on Front Street Coffee's bean list are made up of these two varieties, which shows just how important they are. Caturra originated from a genetic mutation of Bourbon, and because of its short stature, high yield, and sun tolerance, it became a mainstay variety in Central America; Catuai, meanwhile, was developed by crossing Caturra with Mundo Novo, inheriting the former's advantages while improving disease resistance. This article will sort out in detail the origins, agronomic characteristics, and flavor differences of the two, and combine them with Front Street Coffee's cupping experience to help you understand why these two varieties have won the favor of so many coffee farmers.

Yunnan coffee has been steadily gaining attention in recent years, and many coffee enthusiasts are keen to understand its current state of development. When it comes to Yunnan beans, one cannot avoid the concept of "Yunnan small bean," which typically refers to Arabica varieties grown in Yunnan Province, in contrast to the Robusta medium bean cultivated in Hainan. When small bean coffee was first introduced to Yunnan, the varieties planted were Typica and Bourbon, the two oldest Arabica varieties. They offer pure flavor and a round, sweet taste, but their yields are low, they are unsuitable for dense planting, and they have weak disease resistance, so growers prefer varieties that are easier to keep alive and higher-yielding. This article will trace the evolution of coffee varieties in Yunnan, analyze the flavor characteristics of Typica, and recommend three Front Street Coffee Yunnan products and their suitable use scenarios.

Ethiopia is celebrated as the birthplace of Arabica coffee, and its local coffee varieties are as numerous as the stars. However, due to limitations imposed by history, research conditions, and naming systems, the vast majority of these varieties still cannot be individually identified and named. As a result, a broad and romantic term—heirloom—has become synonymous with these native coffee varieties. Heirloom is not a specific variety, but rather a collective term for the large number of coffees in Ethiopia that have not been clearly classified. This article will guide you through the meaning of heirloom, why it is named this way, how local coffees are named, and the brewing and flavor performance of the Yirgacheffe natural red cherry as an example.
