What is a Coffee Cultivar?

A coffee cultivar refers to a variety of coffee plants that have been selectively bred for specific characteristics. This term is derived from "cultivated variety" and is used to describe plants that have distinct, stable properties which are maintained through cultivation. Cultivars in coffee are developed to enhance particular traits such as flavour, yield, resistance to pests, and adaptability to different climates.

Cultivar vs. Variety vs. Species

Before diving deeper, it's essential to understand the difference between species, variety, and cultivar:

  • Species: This is the broadest classification. For coffee, the two primary species are Coffea arabica and Coffea canephora (commonly known as robusta).
  • Variety: This is a naturally occurring subspecies or population within a species. Varieties often arise due to geographical separation and natural mutation.
  • Cultivar: This is a variety that has been selectively bred and cultivated by humans to emphasize desirable traits.

The Importance of Coffee Cultivars

Flavour Profiles: One of the most compelling reasons to explore different coffee cultivars is their impact on flavour. Each cultivar can produce beans with unique taste profiles. For example, the Geisha (or Gesha) cultivar is renowned for its complex, floral, and jasmine-like notes. In contrast, the SL28 cultivar from Kenya is famous for its bright acidity and fruity undertones.

Disease Resistance: Certain cultivars are bred for their resistance to diseases like coffee leaf rust and pests that can devastate coffee crops. By developing resistant cultivars, farmers can ensure more stable yields and reduce the need for chemical pesticides.

Adaptability: Climate change is a significant challenge for coffee cultivation. Some cultivars are bred to be more adaptable to varying environmental conditions, including drought

resistance or the ability to thrive at different altitudes. This adaptability helps maintain coffee production in the face of changing climate patterns.

Yield and Growth Characteristics: Cultivars can also be selected for their growth habits and yield. Some are bred to produce more beans per plant, while others may be chosen for their suitability to particular farming practices, such as shade-grown or sun-grown coffee.

The Importance of Coffee Cultivars

Arabica Cultivars

  • Bourbon: Originating from the island of Réunion, Bourbon is known for its sweet, complex flavours and is the parent of many other cultivars.
  • Typica: One of the oldest cultivars, Typica is known for its clean, sweet cup with excellent acidity and body.
  • Caturra: A natural mutation of Bourbon, Caturra is valued for its high yield and resistance to disease, with a bright, citrusy flavour profile.
  • SL28: Developed in Kenya, SL28 is celebrated for its fruity, wine-like acidity and robust flavour.

Robusta Cultivars

While Arabica cultivars dominate the specialty coffee scene, robusta cultivars also play a crucial role, especially in regions where Arabica cannot thrive.

  • Conilon: A robusta cultivar grown extensively in Brazil, known for its high yield and disease resistance.
  • Nganda: Originating from Uganda, this cultivar is appreciated for its resilience and adaptability to various growing conditions.

How to Choose the Right Cultivar

For coffee farmers, selecting the right cultivar involves balancing several factors:

  • Climate and Soil: Different cultivars thrive in different conditions. Understanding the local climate and soil type is crucial.
  • Market Demand: Some cultivars may fetch higher prices in the market due to their unique flavours or rarity.
  • Farming Practices: The choice of cultivar can influence the farming methods employed, including irrigation, shade management, and pest control.
  • Sustainability: Cultivars that require fewer inputs (like water and pesticides) can be more sustainable and cost-effective.

The Future of Coffee Cultivars

As the demand for specialty coffee continues to grow, so does the interest in developing new cultivars.

Research institutions and coffee organizations are continually working on breeding new varieties that combine excellent flavour with resilience and high yield.

Innovations in biotechnology and traditional breeding methods are opening up new possibilities for the future of coffee cultivation.

  • Genetic Mapping and Hybridization: Advances in genetic mapping are helping scientists understand the coffee genome better, enabling more precise breeding techniques. Hybrid cultivars, which combine traits from different species, are also becoming more common. These hybrids can offer the best of both worlds – the robust flavour of Arabica and the hardiness of Robusta.
  • Sustainable Practices: The focus on sustainability is driving the development of cultivars that are not only high-yielding and disease-resistant but also require fewer resources to grow. This is crucial in ensuring the long-term viability of coffee farming, especially in the face of climate change.

Conclusion

Understanding coffee cultivars is key to appreciating the diversity and complexity of specialty coffee. Each cultivar brings its own unique set of characteristics, from flavour profiles to resilience against diseases. For coffee enthusiasts, exploring different cultivars can be a journey of discovery, offering new and exciting taste experiences. For farmers, selecting the right cultivar is a strategic decision that can impact their livelihood and the sustainability of their farming practices.

As you enjoy your next cup of coffee, take a moment to consider the cultivar behind it. The careful breeding and selection process that went into producing those beans is part of what makes specialty coffee so special. Whether you’re savouring the floral notes of a Geisha or the bright acidity of an SL28, you’re experiencing the culmination of centuries of coffee cultivation and innovation.

Specialty Coffee Cultivars FAQs

What is a coffee cultivar?

A coffee cultivar is a variety of the coffee plant that has been selectively bred by humans for specific traits such as flavor, yield, disease resistance, and adaptability to different climates. The term "cultivar" comes from "cultivated variety," and these plants are cultivated to maintain distinct, stable properties.

How does a coffee cultivar affect the flavor of the coffee?

Different coffee cultivars can produce beans with unique flavor profiles. For instance, the Geisha (Gesha) cultivar is known for its complex, floral, and jasmine-like notes, while the SL28 cultivar from Kenya is celebrated for its bright acidity and fruity undertones. The specific genetic makeup of each cultivar contributes to its distinctive taste.

What is the difference between a coffee species, variety, and cultivar?

  • Species: The broadest classification; the two primary coffee species are Coffea arabica and Coffea canephora (robusta).
  • Variety: A naturally occurring subspecies or population within a species, often arising due to geographical separation and natural mutation.
  • Cultivar: A variety that has been selectively bred and cultivated by humans to emphasize desirable traits like flavor, yield, or disease resistance.

Why are some coffee cultivars more expensive than others?

Certain coffee cultivars, like Geisha, command higher prices due to their unique and desirable flavor profiles, limited availability, and the high demand among specialty coffee enthusiasts. Additionally, some cultivars may require more intensive cultivation practices, contributing to higher production costs and, consequently, higher prices.

How do coffee farmers choose the right cultivar to grow?

Coffee farmers select cultivars based on several factors, including:

  • Climate and Soil: Some cultivars thrive better in specific environmental conditions.
  • Market Demand: Certain cultivars fetch higher prices due to their unique flavors or rarity.
  • Farming Practices: The choice of cultivar can influence the farming methods, such as irrigation, shade management, and pest control.
  • Sustainability: Farmers may choose cultivars that require fewer resources, making them more sustainable and cost-effective.

Are there any new coffee cultivars being developed?

Yes, ongoing research and development are leading to the creation of new coffee cultivars. Advances in genetic mapping and traditional breeding techniques are helping scientists develop cultivars that combine excellent flavor with resilience and high yield. Hybrid cultivars, which combine traits from different species, are also becoming more common, offering a balance of flavor and hardiness.
