The Rare Bourbon Pointu Coffee Bean Explained

You’ve heard of Bourbon coffee, but have you heard of its mysterious, nearly extinct cousin—the Bourbon Pointu? Also known as Bourbon Pointu Léger or simply Pointu, this bean is famed not just for its distinctive shape, but for a curious claim: that it lets you drink more coffee without losing sleep. Where did it come from, why did it disappear, and what makes it so special today?

Bourbon Pointu is a natural mutation of the classic Bourbon coffee variety. First documented in 1810 on Île Bourbon—now Réunion Island—by a local farmer named Leroy, it stood out for its shorter plants and pointed (not round) coffee beans. Confirmed as a Bourbon variant, it’s the same species as your everyday Arabica, just with a radically different caffeine content.

What Is Bourbon Pointu and Why Does It Look Different?

Bourbon Pointu, or Bourbon Pointu Léger, is a spontaneous mutation of the Bourbon coffee variety, originally found growing on Bourbon Island (now Réunion) in 1810. Unlike regular Bourbon beans, which are typically round in shape, Pointu beans are distinctly elongated—or “pointed.” The plants themselves also tend to be shorter and produce fewer cherries. This visual and structural difference was clear enough that botanists at the time classified it as a separate variant within the Bourbon family.

The Science Behind Its Low Caffeine Content

What truly sets Bourbon Pointu apart is its unusually low caffeine level. Research eventually revealed that its caffeine content is approximately half that of a typical Arabica bean. Just how this happened remains debated. Some suggest the mutation occurred spontaneously due to environmental factors on the island. Others believe it may have resulted from natural crossbreeding between Bourbon and the island’s native Coffea mauritiana, a species known for being naturally low in caffeine. Despite studies, no definitive conclusion has been reached—but the effect is real, and the legend grew.

From Literary Fame to Near Extinction

Bourbon Pointu gained legendary status in the 19th century, reportedly beloved by French novelist Honoré de Balzac. Its mild character and purported sleep-friendly caffeine levels made it a refined choice among connoisseurs. But despite its fame, the variety had major flaws for farmers: the plants were weaker, more disease-prone, and yielded far fewer cherries than standard Bourbon. By the early 20th century, most growers had abandoned it in favour of higher-output varieties, and Bourbon Pointu all but disappeared from commercial cultivation.

The Comeback Story: How It Was Saved

In an impressive feat of coffee conservation, Bourbon Pointu was revived between 1999 and 2007 through collaborative efforts by French and Japanese researchers. Using surviving genetic material, they managed to re-establish the variety, though in extremely limited quantities. Today, it is considered one of the rarest and most expensive coffee beans in the world. Its resurrection is a key chapter in coffee history, though the full story is detailed further in specialised texts.

Why Bourbon Pointu Never Left Its Home

Although Bourbon itself spread globally—taking root in Latin America, Africa, and beyond—Bourbon Pointu remained isolated on Réunion Island. The same is true of another rare, naturally low-caffeine coffee from the region: the indigenous Coffea mauritiana, or brown coffee. Neither of these unique, low-caffeine Arabica relatives were exported during the great global migrations of coffee cultivation in the 18th and 19th centuries. As a result, when Bourbon went on to become a global variety—including the well-known red, yellow, and pink Bourbon subtypes—Pointu stayed behind.

Bourbon Coffee: The Larger Family

To understand Bourbon Pointu, it helps to know its parent variety. Bourbon coffee originated on Île Bourbon (Réunion Island), which was called Bourbon Island until the 19th century. It was later introduced to Brazil and spread worldwide, becoming one of the most influential Arabica varieties. Classic Bourbon plants produce rounder beans, have higher yields than Typica, and often display balanced acidity and medium body. Over time, mutations and selections gave rise to popular sub-varieties like Red Bourbon, Yellow Bourbon, and Pink Bourbon—all widely grown today, especially in Brazil, Rwanda, and Colombia.

Other Notable Bourbon Varieties in Modern Coffee

While Bourbon Pointu remains a rarity, other Bourbon mutations thrive in the specialty coffee world. For example:

• Red Bourbon: Known for sweet, wine-like acidity and notes of caramel and chocolate. Common in Brazil, especially in regions like Cerrado and Sul de Minas.
• Yellow Bourbon: Mutated from Red Bourbon, it ripens to an orange-yellow colour and offers a cleaner, brighter cup with notes of peanut brittle and citrus. Often grown at high altitudes for enhanced sweetness.
• Rwanda Red Bourbon: Grown at elevations between 1,700–2,000 metres, Rwandan Red Bourbon is valued for its vibrant acidity, floral notes, and citrus complexity. It forms the backbone of many East African single-origin offerings.

Frequently Asked Questions

What is Bourbon Pointu coffee?

Bourbon Pointu is a natural mutation of the Bourbon coffee variety, first found in 1810 on what is now Réunion Island. It is known for its pointed coffee beans, shorter coffee plants, and significantly lower caffeine content—about half that of regular Arabica. The bean almost disappeared due to low yields and disease susceptibility but was revived in the 2000s through conservation efforts.

Why is Bourbon Pointu so rare?

Bourbon Pointu is rare because it produces fewer cherries per plant, has weaker growth, and is more susceptible to diseases compared to standard Bourbon. These issues made it unfavourable for commercial farming, leading to its near-extinction by the early 20th century. Only a small number of plants survived, and it has been meticulously preserved and revived in recent decades.

Does Bourbon Pointu really help you sleep?

Bourbon Pointu is rumoured to allow for higher coffee consumption with less impact on sleep due to its roughly 50% lower caffeine content than regular Arabica. While this hasn’t been conclusively proven in modern scientific studies, the historical association with better sleep has contributed to its legendary reputation, particularly among 19th-century European consumers.

Where did Bourbon Pointu originate?

Bourbon Pointu originated on Île Bourbon (now Réunion Island) in 1810, where it was discovered by a local farmer. It is a spontaneous mutation of the original Bourbon variety brought to the island in the 18th century. The variant remained geographically isolated and was never exported during the global spread of Bourbon coffee.

What’s the difference between Bourbon and Bourbon Pointu?

Bourbon Pointu is a mutation of the standard Bourbon variety. The key differences include: pointed (rather than round) beans, shorter coffee plants, lower yields, greater disease susceptibility, and—most notably—a significantly reduced caffeine content. Bourbon Pointu is also much rarer and was never widely cultivated outside Réunion Island.

Is Bourbon Pointu still available today?

Yes, Bourbon Pointu is still available today but only in extremely limited quantities. It was revived between 1999 and 2007 through preservation efforts by researchers in France and Japan. Due to its rarity and the difficulty of cultivating it, it remains one of the most expensive and sought-after specialty coffee beans in the world.
