Peru: The World’s Largest Cacao Gene Bank

Recent research has shown that Peru holds more genetic varieties of cacao than any other country in the world. This discovery is a game-changer for cacao producers, chocolate makers, and the overall health of the cacao population.

In this post, we’ll dive deeper into what this means for the future of cacao and why Peru is a crucial player in cacao biodiversity.

Old Beliefs About Cacao’s Genetic Categorization

For years, cacao was classified into three main types: Criollo, Forastero, and Trinitario. This simple classification was widely accepted. However, advancements in genetic analysis have revealed that this view is an oversimplification. Today, we know that cacao's genetic landscape is far more complex than previously thought.

What the Genetic Research Revealed

In 2008, a significant study by Motamayor et al. identified 10 genetic clusters of cacaos. But, more recent research by the Alliance of Bioversity International & CIAT, which analyzed over 4,000 cacao samples, uncovered a much richer genetic diversity. This groundbreaking study found that there are 25 distinct genetic groups of cacaos worldwide. Even more impressive is the fact that Peru is the origin of 16 of these 25 genetic groups (64%), confirming that Peru’s Amazon region is the heart of cacao’s genetic diversity. This makes Peru the world’s primary cacao gene bank.

Why Peru Matters for Cacao Diversity

Peru’s rich genetic diversity makes it a strong contender for the birthplace of cacao. In general, regions that exhibit the highest genetic variation in a species often point to its origin. With its vast and varied landscapes, Peru is home to an exceptional range of cacao genetic lines, making it a likely birthplace of this beloved crop.

The geographical diversity of Peru plays a significant role in this genetic richness. The Andes mountains, which meet the Amazon basin, create unique valleys and micro-climates that have isolated different cacao genetic lines over millions of years. This isolation has allowed these genetic variants to develop independently, leading to a wide array of distinct cacao strains that thrive in this environment.

In addition to genetic diversity, Peru’s cacao is known for its remarkable flavour profiles. A spectrum of bright citric, tropical, berry, herbal, floral, and nutty notes, the genetic variety within Peru's cacao leads to a treasure trove of unique and complex flavours. This range of tastes is essential for producing high-quality, premium chocolate, giving it a competitive edge in the global chocolate market.

What This Means for the Cacao Industry & the Environment

The genetic diversity found in Peru’s cacao is not just important for flavour—it also plays a key role in the future of the cacao industry. A greater number of cacao genetic varieties means a broader range of flavours, which is crucial for the production of premium and high-quality chocolate. This diversity opens up endless possibilities for chocolate makers to create unique products that cater to a wide range of consumer tastes and preferences.

Another major benefit of genetic diversity is resilience. Species with a wider genetic pool are better equipped to adapt to challenges like diseases and climate change. In the case of cacao, preserving its genetic diversity ensures that the crop remains resilient in the face of emerging threats, safeguarding the cacao industry for the future.

However, the need for conservation is urgent. Thousands of cacao varieties remain unstudied and unprotected. Without proper conservation efforts, we risk losing these unique genetic lines, which could impact both the quality and sustainability of cacao production. By safeguarding these varieties, we ensure that cacao can continue to thrive, benefiting both the environment and the farmers who depend on it.
