Coffee Flavor
The flavors of coffee are derived from the breakdown of various nutrients in the green coffee beans during roasting. Heat causes these compounds to degrade into a variety of aromatic molecular structures, resulting in a wide spectrum of flavors. High-quality coffee beans naturally possess a rich aroma that evolves at different temperatures—high, medium, and low—offering a delightful and nuanced experience worth savoring.

Kenya is a prominent producer of East African specialty coffee, with a population of approximately 6 million engaged in the coffee industry, predominantly through smallholder farmers and cooperative societies. Kenyan coffee trees are primarily cultivated at altitudes between 1,400 meters and 2,000 meters, spanning regions including Ruiri, Thika, Kirinyaga, Mt. Kenya West, Nyeri, Kiambu, and Murang'a, with a focus on the foothills of Mt. Kenya and the Aberdare ranges. The main coffee-growing areas encircle Mount Kenya, each possessing its unique regional flavor profiles. For instance, the Nyeri region is renowned for its blackcurrant and prune flavors.
Many coffee-growing regions in Kenya strive to preserve their native forest ecosystems, protecting the natural gene pool and supporting the propagation of wild coffee varieties, thereby fostering diverse coffee trees. In 1930, the unique Kenyan coffee varieties SL28 and SL34 were developed and named by the Scott Laboratories. These varieties emerged in such a conducive environment, benefiting from the region’s commitment to maintaining a healthy and diverse coffee ecosystem.
Producer’s Story – A Pioneering Force in Kenya’s Coffee Industry
In the world of Kenyan coffee, Rockbern is truly a game changer. Its founder, Peter, was born into a coffee-farming family and understands firsthand the hardships and injustices within coffee production. After leaving his hometown to pursue his studies in accounting, he worked in banking and consulting. But in 2021, he and his wife founded the Rockbern coffee brand, fulfilling a promise he once made with his grandfather—to transform Kenya’s coffee industry.
His grandfather, a passionate coffee producer, spent his life believing that Kenyan coffee deserved to be treated with greater fairness and respect. This belief became the core of Rockbern’s philosophy: creating transparency, fairness, and win-win relationships that connect producers and roasters, bringing real change to the coffee sector.
Peter personally visits farming communities across the region, speaking the producers’ language, helping improve quality, and building long-term partnerships. He understands the challenges farmers face, as well as the needs of roasters, allowing him to serve as an honest and efficient bridge between the two. He believes that Kenyan coffee can only thrive when farmers clearly understand market prices and returns, and when roasters have direct access to the story and origin behind each coffee.
From producers to roasters, from employees to consumers, Rockbern builds every part of its business on integrity and well-being. Their commitment is simple: to purchase the highest-quality coffee directly from producers—and ensure that every payment, every reward, goes back into the hands of the farmers.
The coffee tree, botanically classified under the Rubiaceae family and the Coffea subgenus, is an evergreen tree. Coffee beans are the seeds of the coffee fruit. There are three main varieties: Arabica, Robusta, and Liberica. These three varieties cannot crossbreed to produce different subspecies. The world’s specialty coffee comes from the Arabica variety, and within Arabica, there are various subspecies resulting from evolution, hybridization, and mutation.
Arabica Coffee Variety – SL28 SL34
SL34 is an artificial hybrid variety derived from Bourbon in Kenya and Tanzania, developed alongside SL28. Both are well-known for their excellent flavor profiles. While Bourbon has a higher yield compared to Typica, it still has a two-year harvesting cycle, making it a relatively low-yield variety. SL28 and SL34 are iconic Kenyan coffee varieties developed and named by Scott Laboratories (SL) in the 1930s. SL28 carries the lineage of Bourbon, Mokka, and Typica. The original goal of developing SL28 was to produce a high-quality coffee variety that could resist pests and diseases. Although SL28's yield was not as abundant as anticipated, it gained recognition for its excellent sweetness, balance, and complex flavors, with distinctive notes of citrus and dried plum.
SL34, while similar in flavor to SL28, offers a richer and cleaner taste. It has Bourbon heritage and a stronger Typica lineage, making it better suited to withstand heavy rains and challenging weather conditions.

Kenyan Coffee Grading
Kenyan coffee is graded based on two main criteria: bean size and flavor quality. The three most common bean size grades are AA, AB, and PB (Peaberry).
(Coffee Processes)
The term "processing methods" refers to the process of transforming ripe red coffee cherries into dried green beans. Each method has its advantages and disadvantages, influenced by the natural environment and the specific needs of the coffee-producing region. As a result, different regions adopt the processing method most suited to their conditions. This batch uses washed processing methods, described below:
【Washed / Wet Processed】
Also known as the wet process, this method involves removing the skin and pulp of the coffee cherries before drying. The seeds are then fermented in water tanks to eliminate the remaining mucilage on their surface, followed by thorough washing and drying under sunlight or with mechanical dryers.
The washed process produces a cleaner and crisper flavor profile compared to the natural process. Coffees processed this way typically have lighter body, brighter acidity, and distinct fruit flavors. This method is often associated with specialty coffee due to its clarity and vibrant flavor expression.
