The Origins and Cultivation: Robusta vs Excelsa
Robusta: The Resilient Powerhouse
Robusta coffee, scientifically known as Coffea canephora, hails from the depths of central and western sub-Saharan Africa. This hardy plant thrives in lowland areas, typically below 1,000 metres above sea level. Robusta’s name is no coincidence – it’s incredibly resilient to pests, diseases, and harsh weather conditions, making it a favourite among farmers in challenging environments.
The cultivation of Robusta spread from Africa to other parts of the world, with Vietnam now being the largest producer. Its ability to grow in diverse conditions has made it a staple in many coffee-producing countries, including Indonesia, India, and Brazil. Robusta plants are generally taller than their Arabica counterparts, often reaching heights of up to 10 metres in the wild.
One of the most fascinating aspects of Robusta cultivation is its self-pollinating nature. This characteristic not only ensures consistent crop yields but also contributes to the genetic stability of the plant, preserving its unique traits across generations.
Excelsa: The Mysterious Tall Tree
Excelsa coffee, now classified as a variety of Liberica (Coffea liberica var. dewevrei), is perhaps the most enigmatic of all coffee types. Originally discovered in Central Africa, particularly in Chad and the Central African Republic, Excelsa trees are true giants of the coffee world, towering up to 20 metres tall in their natural habitat.
These majestic trees prefer similar growing conditions to Robusta, thriving in low-altitude areas with plenty of rainfall. However, Excelsa’s cultivation is far less widespread, making it a rare and sought-after commodity in the coffee market. You’ll find small-scale Excelsa production in parts of Southeast Asia, particularly in Vietnam and the Philippines.
Excelsa’s limited cultivation is partly due to its complex growing requirements and lower yield compared to Robusta and Arabica. However, this rarity adds to its allure among coffee connoisseurs seeking unique flavour experiences.
Flavour Profiles: Robusta vs Excelsa
Robusta: Bold and Intense
When you sip a cup of Robusta coffee, prepare your taste buds for a strong, full-bodied experience. Robusta is known for its:
- Deep, earthy flavours
- Nutty undertones
- Grainy or rubbery notes
- Lingering bitterness
Many describe Robusta as having a “burnt” or “woody” taste, which can be off-putting to those accustomed to milder coffees. However, when roasted skillfully, Robusta can develop pleasant chocolate and nut flavours that complement its natural intensity.
The high caffeine content in Robusta contributes to its bitter taste, but it also provides a satisfying kick that many coffee lovers crave. If you enjoy your coffee with a robust punch, Robusta might just become your new favourite.
Excelsa: The Flavour Chameleon
Excelsa coffee is a true enigma in the flavour department. Its taste profile is often described as a unique combination of light and dark roast characteristics, making it a fascinating choice for adventurous coffee drinkers. When you try Excelsa, you might notice:
- Fruity and tart notes
- A wine-like acidity
- Mysterious woody undertones
- A complex aftertaste that lingers on the palate
What sets Excelsa apart is its ability to change flavour as it cools. The initial sip might reveal bright, fruity notes, while subsequent tastes could unveil deeper, more roasted flavours. This dynamic flavour profile makes Excelsa an intriguing option for those who enjoy exploring the nuances of their coffee.
Caffeine Content: Which Packs More Punch?
When it comes to caffeine content, there’s a clear winner in this showdown. Let’s break down the numbers:
| Coffee Type | Caffeine Content (per 100g) |
|---|---|
| Robusta | 2.2 – 2.7% |
| Excelsa | 1.0 – 1.5% |
| Arabica | 1.2 – 1.5% |
As you can see, Robusta takes the crown for caffeine content, containing nearly twice as much as Excelsa and Arabica. This high caffeine concentration contributes to Robusta’s bitter taste and makes it a popular choice for espresso blends and instant coffee.
If you’re looking for a serious energy boost, Robusta is your go-to bean. However, if you’re sensitive to caffeine or prefer a more moderate buzz, Excelsa might be the better option. Its caffeine content is similar to Arabica, providing a gentler lift without the jitters that some experience with high-caffeine coffees.
Brewing Methods: Getting the Best Out of Each Bean
Robusta: Embracing the Boldness
To truly appreciate Robusta’s unique characteristics, consider these brewing methods:
- Espresso: Robusta’s high caffeine content and crema-producing qualities make it excellent for espresso. Try a pure Robusta shot or blend it with Arabica for a balanced experience.
- French Press: The full-immersion brewing of a French press allows Robusta’s strong flavours to shine. Use a coarse grind and experiment with shorter steeping times to avoid over-extraction.
- Cold Brew: Surprisingly, cold brewing can mellow out Robusta’s bitterness while preserving its chocolatey notes. Steep for 12-24 hours for a smooth, refreshing drink.
- Vietnamese Phin Filter: This traditional method pairs perfectly with Robusta, creating a strong, concentrated brew often served with sweetened condensed milk.
Remember, Robusta’s intense flavour means you might want to adjust your coffee-to-water ratio. Start with a slightly lower coffee amount than you’d use for Arabica and adjust to taste.
Excelsa: Unlocking the Mystery
Brewing Excelsa requires a bit of experimentation to fully appreciate its complex flavour profile. Here are some methods to try:
- Pour-Over: The controlled pour-over method allows you to highlight Excelsa’s fruity notes. Use a medium-fine grind and pay attention to water temperature – around 90°C works well.
- AeroPress: This versatile brewer can bring out Excelsa’s unique characteristics. Try both the standard and inverted methods to see which you prefer.
- Siphon: If you’re feeling adventurous, a siphon brewer can accentuate Excelsa’s wine-like acidity and complex flavours.
- Cupping: To truly understand Excelsa’s flavour evolution, try cupping it. This will allow you to taste how the flavour changes as the coffee cools.
Given Excelsa’s rarity, it’s worth taking the time to experiment with different brewing parameters. Document your experiences to find your perfect cup.
Popularity and Availability in the Global Coffee Market
Robusta: The Unsung Hero of the Coffee World
While Arabica dominates the specialty coffee scene, Robusta holds a significant place in the global coffee market. Here’s why:
- Robusta accounts for about 40% of global coffee production
- It’s a key ingredient in many espresso blends, providing body and crema
- Instant coffee often relies heavily on Robusta beans
- Its hardy nature makes it a more sustainable option in some regions
You’ll find Robusta widely available in supermarkets, especially in instant coffee and budget-friendly blends. However, high-quality, single-origin Robusta is becoming more common in specialty coffee shops as baristas and roasters explore its potential.
Excelsa: The Rare Gem
Excelsa, on the other hand, is a niche player in the coffee market:
- It represents less than 1% of global coffee production
- Availability is limited, often found only through specialty roasters
- Its unique flavour profile makes it popular among coffee enthusiasts seeking new experiences
- Some roasters use small amounts of Excelsa in blends to add complexity
If you’re keen to try Excelsa, your best bet is to seek out specialty coffee shops or online retailers that focus on rare and exotic beans. Be prepared to pay a premium for this uncommon coffee variety.
Health Benefits of Robusta vs Excelsa
Both Robusta and Excelsa offer health benefits, thanks to their caffeine content and antioxidant properties. However, there are some differences worth noting:
Robusta:
- Higher chlorogenic acid content, a powerful antioxidant

- Potentially beneficial for liver health
- Could aid in improving mental focus and alertness
Excelsa:
- Contains a unique blend of antioxidants
- Moderate caffeine content may provide a gentler energy boost

It’s important to remember that coffee’s health benefits are best enjoyed in moderation. Excessive consumption of any type of coffee can lead to negative side effects, such as insomnia or increased anxiety.

Many Italian-style espresso blends contain up to 20% Robusta to achieve that perfect, rich crema. When blending with Robusta, start with small percentages and adjust to taste.

While less common in blends, Excelsa can add unique characteristics:
- Introduces complexity and depth to Arabica blends
- Can brighten up dark roasts with its fruity notes
- Adds an interesting dimension to espresso blends
