Robusta's share of global coffee production has climbed from 25% in the early 1990s to 40%, with market demand continuing to rise, yet breeding and improvement efforts have long lagged behind. WCR predicts that if consumption growth overlaps with the climate crisis, the global coffee supply could face severe shortages in 2024. To address this, WCR is about to launch a Robusta breeding program using a large amount of genetic material provided by CIRAD, and will work with major producing countries to build a global breeding network. Meanwhile, planting trials in Uganda have already been implemented, distributing nearly 50,000 disease-resistant Robusta (KR) trees to farmers. Front Street Coffee continues to monitor the industry trends and variety innovations in Robusta. [more…]

In the naming of coffee varieties, combinations of letters and numbers are not uncommon, but F1 is not a single variety—it is a collective term for a class of hybrid progeny. It originated from a breeding program promoted jointly by the French Agricultural Research Centre for International Development and the Coffee Institute of Costa Rica, among other institutions, after the major leaf rust outbreak of the 1970s, aimed at cultivating a new generation of coffee that is high-yielding, disease-resistant, and excellent in flavor. Although F1 varieties possess many advantages, they are also difficult to promote on a large scale due to the difficulty of propagation and high costs. This article will guide you through the background of F1's creation, its selection process, its main characteristics, and important commercialized representatives such as H1 and Ruiru 11, while combining recommendations from Front Street Coffee to present this innovative achievement in the field of coffee breeding.

Sudan Rume is an ancient coffee variety with extremely low yield yet outstanding flavor, which shot to fame after being selected by the 2015 WBC champion. It originated in the border region between the Boma Plateau and the Rume Valley in Africa, was only formally documented in the 1940s, and has long been used as a hybrid father plant since then. Front Street Coffee once tasted a washed Sudan Rume batch from Costa Rica, and its bright acidity and juicy mouthfeel reminiscent of lemon and plum were deeply impressive. This article will outline this rare variety's historical origins, plant characteristics, flavor performance, and important position in modern breeding. [more…]

SL28 is one of Africa's most legendary coffee varieties. After being selected in Kenya in the 1930s, it gradually spread to Arabica-growing regions such as Uganda, and in recent years it has traveled even farther to Latin America. It is suited to cultivation at medium to high altitudes; it is drought-tolerant yet susceptible to disease, and its flavor is exceptionally elegant, often with floral notes. Front Street Coffee's Little Tomato coffee beans are precisely a combination of SL28 and SL34, displaying layers of pear, smoked plum, yellow sugar, and more. This article will trace the history of SL28's selection and breeding at the Scott Agricultural Laboratories, sort out its genetic relationship with the Bourbon genome, and introduce specific information about Kenya's Asali processing plant, helping coffee enthusiasts fully understand this variety's origins and development as well as its potential in the cup.

Kenyan coffee has long been famous for the SL series of varieties, but although SL varieties are outstanding in quality, they are extremely vulnerable to pests and diseases. To address this dilemma, the Kenyan coffee industry began promoting new varieties that combine disease resistance with climate adaptability, and Ruiru 11 is one of the representatives. This variety, officially released in 1985, has what kind of breeding story behind it? Why is it welcomed by farmers, yet also triggers quality controversy? This article will give you a comprehensive understanding of the background of Ruiru 11's creation, its varietal characteristics, cultivation advantages, and the challenges it currently faces. If you are interested in Kenyan coffee, Front Street Coffee also has related beans available for tasting. [more…]

When you shop for coffee beans, have you ever noticed that certain origins always seem to grow just a few fixed varieties? Brazil, for instance, is dominated by Bourbon, while Jamaica Blue Mountain is inseparable from Typica. Behind this lies both the logic of variety dissemination and natural adaptation, as well as a chapter of coffee history rewritten by leaf rust. That devastating disease at the end of the 19th century forced many producing countries to turn to research on disease-resistant new varieties, leading to the establishment of national coffee research institutes. This article will walk you through the origins and development of common laboratory varieties such as Catuai, SL28, SL34, Ruiru 11, and H1, and how they became the mainstays of today's producing regions. It will also mention related beans selected by Front Street Coffee, offering you a practical buying reference. [more…]

The natural decaffeinated coffee breeding program at Brazil's Campinas Agronomic Institute (IAC), which has spanned more than two decades, has now entered the stage of definitive verification. Researchers are cultivating and screening hybrid coffee plants derived from different varieties, with the goal of developing coffee varieties that are naturally low in caffeine or even caffeine-free without the need for industrial decaffeination. If this breakthrough ultimately comes to fruition, it will profoundly change the commercialization landscape of decaffeinated coffee in major markets such as the United States and Europe. According to forecasts by market research institutions, the global decaffeinated coffee market will reach US$28.86 billion by 2030, with young health-conscious consumers as the main driving force. Front Street Coffee will also continue to follow the subsequent progress of this transformative research. [more…]
