SL34 is a coffee variety that is highly regarded in the world of specialty coffee. It is known for its exceptional cup quality and is widely cultivated in several coffee-producing countries, primarily in East Africa.
Here is some information about the SL34 coffee variety:
Origin: SL34 stands for “Scott Agricultural Laboratories #34,” which refers to the location where this coffee variety was developed. It was created by Scott Agricultural Laboratories in Kenya in the 1930s.
Genetic Background: SL34 is a hybrid coffee variety derived from the Bourbon and Typica coffee varieties, which are both renowned for their excellent flavor profiles and adaptability.
Characteristics: Flavor Profile: SL34 is known for its exceptional cup quality. It typically produces coffee with a well-balanced, bright acidity, a full body, and a complex flavor profile. The flavor notes often include citrus, stone fruit, and floral undertones. The coffee can also exhibit a pleasant sweetness and sometimes hints of blackcurrant.
Growing Conditions: SL34 is well-suited to high-altitude regions with rich volcanic soil, which provides the ideal conditions for its growth. It thrives at elevations between 1,500 to 2,100 meters above sea level.
Disease Resistance: One of the reasons SL34 was developed was to create a coffee variety that had good resistance to diseases like coffee leaf rust (Hemileia vastatrix). While it is more disease-resistant than some other varieties, it is not immune and still requires proper care and maintenance.
Cultivation Areas: SL34 is primarily grown in East African countries, particularly in Kenya, Tanzania, and Ethiopia. However, it has also been planted in other coffee-producing regions around the world due to its favorable cup qualities.
Varietal Development: Over the years, various sub-varieties of SL34 have emerged, such as SL28, which was developed alongside SL34. These sub-varieties share some characteristics but also have unique flavor profiles and adaptability to different growing conditions.
Sustainability: SL34 is often favored by specialty coffee growers and buyers due to its high cup quality. It has contributed to the sustainability of coffee farming by fetching premium prices in the specialty coffee market, which can benefit coffee-producing communities.
Overall, SL34 is highly valued for its outstanding cup quality, making it a sought-after choice for coffee producers and enthusiasts who prioritize flavor and quality in their coffee beans. Its unique flavor profile and adaptability to various growing conditions make it an important coffee variety in the specialty coffee industry.
