What Kenyan Coffee Does Starbucks Use?

If you’ve ever sipped a bright, juicy cup of Kenyan coffee and wondered why it stands out so sharply from other African origins, you’re not alone. The vivid citrus, wine-like depth, and structured acidity make Kenyan beans some of the most distinctive in the world—but how does a global giant like Starbucks choose which Kenyan coffees to buy?

In short: Starbucks doesn’t buy Kenyan coffee through auctions or specify grades like 'AA' or 'A'. Instead, its suppliers select lots based on cup quality and send samples for approval. Starbucks prioritizes flavour—especially the signature Kenyan fruitiness—over bean size or official grading.

What Makes Kenyan Coffee Different?

Kenyan coffee is celebrated for its complex flavours, high acidity, and full body. Typical tasting notes include grapefruit, berries, blackcurrant, and wine-like tones. The acidity is often described as juicy, almost like citrus juice, and the body is medium—balanced, not thin or heavy.

The country’s location along the equator on Africa’s eastern coast, just south of Ethiopia, gives it ideal coffee-growing conditions. Its high-altitude plateaus, volcanic soils, and consistent rainfall create an environment where coffee cherries develop slowly, concentrating flavour and acidity.

How Is Kenyan Coffee Processed?

Nearly all Kenyan coffee sourced by Starbucks is processed using the washed (wet) method. In this method, coffee cherries are de-pulped, then fermented for around 48 hours to break down the mucilage. After fermentation, the beans are soaked in fresh water for another 24 hours to ensure complete mucilage removal. This double washing process enhances the coffee’s inherent fruitiness and clarity.

This meticulous processing contributes significantly to the clean, vibrant cup profile that Kenyan beans are known for—especially that standout citrus acidity.

Why SL28 and SL34 Matter

Among the many coffee varieties grown in Kenya, two stand out: SL28 and SL34. These were developed by Kenya’s Scott Laboratories (SL) in the 1930s as part of a research initiative to identify drought-resistant, high-quality cultivars.

SL28 is famous for its intense blackcurrant, citrus, and winey flavours with deep, resonant acidity—often compared to grapes or plums. SL34 also delivers bright fruit acidity but with more nutty and spice notes. Both are grown at high altitudes, typically between 1,200 and 2,000 metres, where cooler temperatures slow cherry maturation and develop complex sugars and acids.

These varieties, combined with Kenya’s high-phosphorus volcanic soils, produce a fruit-forward acidity that has redefined expectations for what coffee can taste like.

Does Starbucks Buy Kenyan Coffee Through Auctions?

No. Unlike many other buyers, Starbucks does not purchase Kenyan coffee at the country’s official auction. Instead, its suppliers independently select lots they believe will meet Starbucks’ flavour standards, then send samples for evaluation. Starbucks bases its purchasing decisions entirely on taste—not bean size, auction grade, or visual traits.

Grades like 'AA' or 'A' refer only to bean size, not quality or flavour. That’s why Starbucks focuses on cup quality over classification.

How Does Kenya’s Coffee Infrastructure Support Quality?

Kenya has a highly organized coffee auction system overseen by the Nairobi Coffee Exchange. Before auction, every lot is cupped and graded by experts. This structure ensures transparency and quality control, helping buyers identify exceptional lots—even if Starbucks chooses not to buy through it.

The country’s coffee sector is supported by a strong research institution (Scott Laboratories), well-maintained growing regions, and a long-standing tradition of producing specialty-grade beans.

Frequently Asked Questions

Does Starbucks buy Kenyan coffee at auction?

No. Starbucks does not purchase Kenyan coffee through the Nairobi Coffee Exchange auction. Instead, its suppliers select and sample lots they believe match Starbucks’ flavour profiles, and those are approved internally. The company prioritizes taste over auction grades or processes.

What coffee varieties does Starbucks prefer from Kenya?

While Starbucks does not publicly specify varieties, the most celebrated Kenyan coffee types are SL28 and SL34. These are known for their vibrant fruit flavours, especially blackcurrant, citrus, and wine-like notes, as well as high acidity and full body. They are grown at high altitudes, typically between 1,200–2,000 metres.

Why doesn’t Starbucks use Kenyan AA grade coffee?

Starbucks avoids specifying Kenyan coffee grades like 'AA' or 'A' because these grades refer only to bean size, not flavour quality. The company selects coffee based on taste—particularly the bright, fruity acidity and complexity that Kenyan beans offer—rather than physical characteristics or auction classifications.

What processing method is used for Kenyan coffee bought by Starbucks?

The vast majority of Kenyan coffee purchased by Starbucks is processed using the washed (wet) method. This involves fermenting the depulped coffee for 48 hours, then soaking it in fresh water for another 24 hours to remove all mucilage. This process enhances the coffee’s acidity and clarity, contributing to its signature bright, juicy cup.

How does Kenyan coffee compare to Ethiopian coffee?

Kenyan coffee is often compared to Ethiopian coffee, especially Yirgacheffe or Sidamo. Both origins feature bright acidity and fruity notes, but Kenyan coffees tend to have a more wine-like, structured acidity with prominent citrus and blackcurrant flavours. Ethiopian coffees may lean more toward floral or blueberry notes and often have a lighter body.

What foods pair well with Kenyan coffee?

Kenyan coffee’s bright acidity and fruit notes pair well with grapefruit, berries, seedless raisins, grapes, and oranges. Its complexity also complements desserts or savoury dishes with citrus or tropical fruit elements.
