This coffee comes from Oaklands Estate in Kiambu County, Kenya, a historic coffee-growing area just north of Nairobi.

Grown at around 1,550–1,700 metres above sea level, this single-estate coffee brings together several classic Kenyan Arabica varieties and uses the traditional fully washed process associated with some of the country’s most distinctive coffees.

The result is a bright, juicy and structured cup with notes of blackcurrant, cranberry, cola and sweetness.

Oaklands Estate

Oaklands is a long-established coffee estate in the Juja area of Kiambu County.

Coffee has been grown in this part of Kenya for generations, and the estate forms part of the wider Tatu Coffee farming network.

The region benefits from high elevation, strong equatorial sunlight, cooler nights and rich volcanic soils, all of which create excellent conditions for producing dense, high-quality Arabica.

Unlike many Kenyan coffees that are produced by groups of smallholder farmers and processed through cooperative washing stations, this is a single-estate lot.

That gives the coffee a particularly strong level of traceability, with the growing, harvesting and primary processing all connected to the same estate.

High-Altitude Kenyan Arabica

The coffee is grown at approximately 1,550–1,700 MASL.

At these elevations, cooler temperatures slow the ripening of the coffee cherries, allowing sweetness, acidity and flavour complexity to develop gradually before harvest.

The slower growth also contributes to denser coffee beans, which can respond particularly well to careful roasting.

Classic Kenyan Varieties

This lot combines:

Acaia • K7 • Ruiru 11 • SL28

These varieties represent a mixture of traditional and more modern Kenyan coffee genetics.

SL28 is particularly famous for its fruit intensity, vibrant acidity and complex cup profile.

K7 is another long-established Kenyan variety, while Ruiru 11 was developed to combine quality with improved resistance to important coffee diseases.

Together, these varieties help create the layered fruit and sweetness found in the cup.

Traditional Fully Washed Processing

This coffee is processed using the classic Kenyan fully washed method.

After harvesting, ripe cherries are carefully selected before being depulped to remove the outer fruit.

The parchment coffee is then fermented for approximately 12–48 hours, allowing the remaining mucilage to break down naturally.

Once fermentation is complete, the coffee is thoroughly washed in clean water.

Density Grading & Soaking

During washing, the coffee passes through channels that also allow it to be separated by density.

The heavier, denser beans can be separated from lower-density material before the coffee moves into a soaking stage.

This additional soaking step is a traditional feature of Kenyan washed processing and contributes to the clean, structured character associated with many premium Kenyan coffees.

Raised African Bed Drying

After washing and soaking, the parchment coffee is transferred to raised African drying beds.

The coffee is sun-dried for approximately two weeks, with regular turning to encourage even moisture reduction.

The parchment is also protected from excessive midday heat, overnight moisture and rain where necessary.

Raised beds improve airflow around the coffee, helping create a slow and controlled drying process.

AA Top – Screen 18+

This lot is graded:

AA Top – Screen 18+

Kenya’s AA classification primarily refers to bean size, with AA coffees representing one of the larger standard grades.

The 18+ screen size provides good physical consistency for roasting.

Bean size alone does not determine cup quality, but when combined with careful harvesting, high-altitude growing conditions and controlled processing, it can form part of a very high-quality green coffee.

In the Cup

Expect a vibrant and classically Kenyan profile with notes of:

Blackcurrant • Cranberry • Cola • Sweet

The blackcurrant provides a deep, concentrated dark-fruit character.

Cranberry adds a brighter red-fruit acidity.

The cola note brings together caramel-like sweetness, gentle spice and lively acidity, while the overall cup remains clean and sweet.

The result is a bright, juicy and structured coffee with plenty of fruit character.

For Roasters

This coffee is particularly well suited to light-to-medium roasting.

A lighter roast should preserve more of the blackcurrant, cranberry and lively Kenyan acidity.

Moving towards a medium roast will develop more sweetness, body and cola-like character while maintaining the coffee’s fruit profile.

For espresso, careful development can produce a sweet and vibrant shot with plenty of blackcurrant character.

Recommended Brewing Methods

Once roasted, Oaklands Estate should perform particularly well with:

• V60 and pour-over
• AeroPress
• Batch filter
• Cafetière
• Single-origin espresso

Filter brewing will emphasise the brighter fruit and acidity, while espresso can highlight the coffee’s sweetness, body and deeper blackcurrant character.

A Classic Kenyan Single Estate

Kenya AA Oaklands Estate combines several of the characteristics that make Kenyan coffee so distinctive:

High-altitude growing conditions, classic Kenyan varieties, traditional fully washed processing, raised-bed drying and AA Top preparation.

Its single-estate traceability also makes it particularly interesting for roasters who want to explore the character of one specific Kenyan farm rather than a wider regional or cooperative blend.

Kenya is one of the world’s most distinctive coffee-producing countries, known for coffees with bright acidity, deep fruit character and exceptional clarity.

Most coffee is grown in the central highlands around Mount Kenya and the Aberdare Range, as well as in regions such as Kiambu, Nyeri, Kirinyaga, Murang’a and Embu. These areas benefit from high elevations, fertile volcanic soils, warm days and cooler nights.

High-Altitude Growing

Much of Kenya’s specialty coffee is grown between approximately 1,400 and 2,000 metres above sea level.

At these elevations, coffee cherries ripen more slowly. This extended maturation period allows sugars, acidity and flavour compounds to develop gradually, often producing dense green coffee with excellent structure and complexity.

Kenya’s equatorial location also provides relatively consistent daylight throughout the year, while higher elevations help moderate temperatures.

Volcanic Soils

Many of Kenya’s best-known coffee regions sit on deep, red volcanic soils.

These soils are generally well drained and rich in minerals, providing strong growing conditions for Arabica coffee.

Combined with adequate rainfall and elevation, this environment contributes to the concentration and intensity often associated with Kenyan coffees.

Kenyan Coffee Varieties

Kenya is particularly famous for several Arabica varieties developed or selected for local growing conditions.

SL28 and SL34 are two of the best known and are closely associated with the classic Kenyan cup profile.

Other widely planted varieties include:

K7 • Ruiru 11 • Batian

as well as smaller amounts of other regional and experimental varieties.

SL28 in particular has become highly valued for its ability to produce intense fruit character, sweetness and structured acidity when grown at altitude.

Smallholder Farmers and Estates

Kenyan coffee is produced through two main systems.

A large proportion comes from smallholder farmers, who deliver freshly harvested cherries to cooperative-owned washing stations, often called factories.

These washing stations combine coffee from farmers within a local area and handle the processing centrally.

Kenya also has a long history of larger coffee estates, particularly around areas such as Kiambu.

Estate coffees can offer greater farm-level traceability because growing, harvesting and processing take place within the same operation.

Selective Hand Harvesting

Coffee cherries are generally picked by hand, with farmers and estate workers selecting ripe red cherries during harvest.

Selective picking is important because ripeness has a major effect on sweetness and cup quality.

Cherries may be harvested over several passes as different parts of the tree mature.

Traditional Kenyan Washed Processing

Kenya is especially famous for its fully washed processing method.

After harvesting, ripe cherries are sorted and depulped to remove the skin and most of the fruit.

The coffee is then fermented, commonly for around 12–48 hours, depending on temperature and local conditions.

This fermentation allows the remaining mucilage surrounding the parchment coffee to break down.

Washing and Density Grading

After fermentation, the coffee is washed through channels using clean water.

These channels also allow the coffee to be separated by density.

Heavier, denser beans tend to sink, while lighter material can be separated out.

This additional sorting stage helps improve physical consistency and cup quality.

Soaking

Many traditional Kenyan washed coffees also undergo an additional soaking stage after washing.

The parchment coffee is placed in clean water before drying.

This step forms part of the classic Kenyan processing method and is associated with the clean, vibrant character found in many premium lots.

Raised African Bed Drying

Once washed, the coffee is usually transferred to raised African drying beds.

The parchment is spread in thin layers and turned regularly to ensure even drying.

The coffee may also be covered during the hottest part of the day, overnight or during rain to help control the drying rate.

Depending on weather conditions, drying commonly takes around 10–20 days.

Raised beds allow air to circulate above and below the coffee, encouraging gradual and consistent moisture reduction.

Kenya’s Coffee Grading System

Kenya uses a detailed physical grading system based largely on bean size and shape.

Common grades include:

AA • AB • PB • C • E

AA is one of the larger standard grades, typically representing beans retained above approximately screen 17/18.

AB is slightly smaller but can still produce exceptional cup quality.

PB, or Peaberry, refers to rounded beans where one seed has developed inside the coffee cherry instead of the usual two.

Bean size alone does not determine quality. Variety, altitude, harvesting, processing and lot selection are all equally important.

The Classic Kenyan Cup Profile

Kenyan coffees are famous for their distinctive fruit character and lively acidity.

Depending on region, variety and processing, flavours can include:

Blackcurrant • Red Berries • Cranberry • Citrus • Grapefruit • Plum • Tomato • Cola • Brown Sugar

Washed coffees tend to be particularly clean and vibrant, while naturally processed Kenyan coffees can offer heavier sweetness, fuller body and more jam-like fruit.

A Distinctive Coffee Origin

Kenya’s combination of high altitude, volcanic soils, distinctive Arabica varieties and meticulous washed processing has created one of the most recognisable coffee styles in the world.

Whether produced by a smallholder cooperative or a single estate, premium Kenyan coffees are prized for their clarity, fruit intensity, structured acidity and exceptional roasting potential.
