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…]

Although Kenya and Ethiopia are both in Africa and not far apart, their coffee flavor profiles are completely different—the former is known for its sweet-and-sour notes reminiscent of dark plums, cherry tomatoes, and caramel. This uniqueness stems both from the volcanic soil at altitudes of 1,600 to 2,100 meters from the capital Nairobi to the Kenyan highlands, and from the contribution of classic varieties such as SL28 and SL34. This article will trace the evolution of Kenyan coffee varieties: from the Bourbon variety introduced by French missionaries, to the selection of SL28 and SL34 by the Scott Laboratories, to Ruiru11 developed in response to pests and diseases, and Batian, which was released in 2010. It also includes brewing suggestions and flavor descriptions for Front Street Coffee Kenya·Asalia, for the reference of coffee enthusiasts. [more…]

Kenyan coffee is renowned worldwide for its bright fruit acidity and thick, juicy body, and SL28 and SL34 are the core varieties that shape this classic flavor. These two varieties were developed by the Scott Laboratories over nearly three decades and released in the 1950s, profoundly influencing the landscape of Kenya's coffee industry. However, the threat of pests and diseases gave rise to new varieties such as Ruiru 11 and Batian. This article will trace the origins, flavor characteristics, and current cultivation status of these varieties, and introduce the variety information of Front Street Kenya Asalia coffee beans, taking you deep into the world of Kenyan coffee varieties.

Kenyan coffee is renowned worldwide for its bright, uplifting fruit acidity and full, rich, juicy body, and SL28 and SL34 are the core varieties that shape this classic style. These two varieties, bred by the Scott Laboratories, have become stars of the specialty coffee world thanks to their complex flavors of dark plum, citrus, and stone fruit. However, their vulnerability to leaf rust and coffee berry disease gave rise to the later, more disease-resistant Ruiru 11 and Batian. This article will systematically trace the evolution of Kenyan coffee varieties—from their origins and flavor characteristics to cultivation performance and current market status—and answer the question of whether Ruiru is a coffee variety.

Kenyan coffee is renowned for its clean, translucent cup and bright, full-bodied fruit acidity. Behind this signature flavor lies both the gift of high altitudes and phosphorus-rich volcanic soil in the highlands, and a century of accumulated variety selection and breeding. From the Reunion Bourbon brought by French missionaries in the late 19th century, to SL28 and SL34 selected by the Scott Agricultural Laboratories from 42 lines, to Ruiru 11 and Batian developed to combat berry disease, Kenya's coffee variety history is a story of wrestling with disease, yield, and flavor. This article will outline the genetic origins, cultivation performance, and flavor differences of the main cultivated varieties, and introduce Front Street Coffee's Kenyan beans from the Thika region—selected from SL28 and SL34, processed with the K72 washed method, presenting notes of cherry tomato and dark plum.

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.

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 Embu region of Kenya is located near Mount Kenya, at an altitude of about 1,300-1,900 meters, with fertile volcanic soil, and tea is also an important local export crop. This region is dominated by smallholder farmers, and the fresh cherries are mostly handed over to washing stations under cooperatives for unified processing and export. The ENA factory uses hand sorting, multiple fermentation and scrubbing, and raised-bed drying for 14-21 days, making the flavor cleaner and more acidic. In terms of varieties, SL28 and SL34 originated from breeding in the 20th century for resistance to berry disease. SL28 belongs to the Bourbon genetic group, is drought-tolerant, and has a pure flavor; in the 1970s, Ruiru11 was introduced, which is resistant to leaf rust, tolerant to berry disease, and can be planted densely. The Kiri coffee beans recommended by Front Street Coffee come from the Embu ENA cooperative, at an altitude of 1,600-1,800 meters, with varieties SL28 and Ruiru11, washed processing, and flavors of berries, smoked plum, pomelo, and Earl Grey tea.
