Yellow Bourbon Coffee from Colombia’s Huila Diamond Estate

If you’ve ever wondered why some Colombian coffees taste more like dessert than diner fuel—think hazelnut cream, caramel drizzle, and a silky mouthfeel—this is the bean that explains it. Not all Colombian coffees are bold and bitter. Some, grown at elevation under the right conditions, deliver delicate sweetness and complex fruit notes. The trick is knowing which ones, and why.

The answer is Colombia Huila El Diamante Yellow Bourbon: a single-origin lot grown at 1,667 metres above sea level, processed using a unique dry fermentation and four-stage washed method, and sourced from the Diamond Estate in the Huila region. It delivers notes of hazelnut, pistachio, caramel, and a creamy body—no milk required.

Why Colombian Coffee Stands Apart

Colombian coffee has been cultivated since 1808, when a priest first introduced it from French Guiana via Venezuela. The country’s mountainous terrain, consistent rainfall, and cool temperatures created ideal growing conditions. Today, Colombia is the world’s second-largest coffee producer and the largest exporter of both Arabica and washed coffee beans. Unlike Brazil’s often industrial-scale production, much of Colombia’s output comes from smallholder farms in high-altitude regions, producing vibrant, balanced cups.

The most famous traditional regions include Medellín, Armenia, and Manizales—collectively known as “MAM”—which have historically delivered well-balanced, medium-bodied profiles. But the real evolution in flavour comes from Colombia’s southern highlands, where altitudes exceed 1,500 metres and microclimates foster brighter acidity, deeper sweetness, and more complex fruit and floral tones.

What Makes Huila Special

Huila, particularly the Vera Plateau where the Diamond Estate is located, has become synonymous with high-scoring competition coffees. The region benefits from volcanic soils, high elevations, and a stable climate—all factors that slow cherry maturation and boost sweetness and acidity. Unlike the classic chocolate-and-nut profile associated with mass-market Colombian beans, Huila’s best lots often express red fruit, berries, caramel, and a creamy, almost buttery mouthfeel.

The area has gained attention not just for consistency but for innovation in processing. Many farms, including Diamond Estate, experiment with extended fermentation, selective harvesting, and unique drying techniques to highlight specific flavour profiles beyond the traditional.

The Role of Yellow Bourbon

Yellow Bourbon is a natural mutation of the Bourbon variety (itself a mutation of Typica), named for the island of Bourbon (now Réunion). Unlike its red counterpart, Yellow Bourbon cherries ripen to a golden yellow, and the variety is known for its elevated sweetness and complex acidity when grown at high elevations. However, it’s lower-yielding and more susceptible to weather, which explains its limited planting historically—despite its exceptional cup quality.

In the hands of skilled farmers at high altitudes, Yellow Bourbon can produce some of the most nuanced and dessert-like profiles in specialty coffee: think almond, marzipan, tropical fruit, and a syrupy body. This particular lot from Diamond Estate leans into those traits with remarkable clarity.

How the Coffee Was Processed

This Yellow Bourbon lot underwent an innovative processing method designed to enhance both clarity and sweetness. After harvest, the coffee cherries were depulped to remove the skin, then placed in a dedicated fermentation tank for 24 hours without water. This dry, anaerobic-style fermentation allowed natural microbes to break down sugars and alcohols in the mucilage.

Following this, the beans went through a unique four-stage washed process—essentially four separate water washes—to ensure all residual fruit material was removed. This meticulous approach not only stabilises the green bean quality but also amplifies the inherent acidity and sweetness of the Yellow Bourbon variety. Finally, the beans were dried mechanically, preserving their delicate profiles.

The result is a high-quality, repeatable lot with pronounced hazelnut, pistachio, and caramel notes, plus a creamy texture that lingers on the palate. No roast profile was given, but such beans typically shine at light to medium roasts to preserve their intricate fruit and sugar tones.

Frequently Asked Questions

What is special about Yellow Bourbon coffee?

Yellow Bourbon is a mutation of the Bourbon coffee variety. It ripens to a yellow colour rather than red, and when grown at high altitudes—like 1,667m in Colombia’s Huila region—it develops intense sweetness, complex acidity, and flavours such as hazelnut, pistachio, and caramel. It’s lower-yielding and more delicate than other varieties, which is why it’s less common but highly prized in specialty coffee.

Where is the Diamond Estate coffee farm located?

The Diamond Estate is located in the Vera Plateau within Colombia’s Huila region, a part of the South American country’s famed southern coffee-growing area. The farm sits at an elevation of 1,667 metres above sea level, in a zone known for producing high-scoring, fruit- and caramel-forward specialty coffees.

What processing method was used for this coffee?

This Yellow Bourbon coffee was processed using a dry fermentation method without water for 24 hours, followed by a unique four-stage washed process to remove all fruit residues. The beans were then dried mechanically. This method enhances both sweetness and clarity, resulting in a clean, sweet cup with nutty and caramel notes.

What does this Colombian coffee taste like?

According to the producer, this coffee expresses flavours of hazelnut, pistachio, caramel, and has a creamy body. It’s a sweet, balanced single-origin lot with no mention of strong bitterness or earthiness—ideal for pour-over or light roasting styles that highlight its delicate profiles.

Why is Huila known for high-quality coffee?

Huila, especially areas like the Vera Plateau, features high altitudes, rich volcanic soils, and stable microclimates. These factors slow down coffee cherry development, leading to greater sugar accumulation and more complex acidity. The region is celebrated for producing coffees with bright fruit, floral notes, caramel, and creamy textures—often scoring highly in competitions.
