Caturra Chiroso (linked to existing Chiroso record)

The term 'Caturra Chiroso' refers to a specific, compact-growing coffee cultivar that has gained significant attention in the specialty coffee sector, particularly for its performance in high-level competitions. The name 'Chiroso' is a local Colombian slang term used in rural areas to describe something slightly elongated, a descriptor that initially led producers to identify the plant by its physical appearance rather than its genetic heritage. For years, the coffee was categorized by local growers into three distinct subtypes: Chiroso, Caturra Chiroso, and Bourbon Chiroso, with the 'Caturra' designation applied to the shorter, more compact plants found in the region.

For a long time, the origins of the variety were shrouded in speculation. Because of its compact stature and high yield potential, many early observers assumed it was a natural mutation of the Caturra variety, which itself is a dwarf mutation of Bourbon discovered in Brazil. Others hypothesized it was a regression of the taller Bourbon Chiroso. However, these field-based observations lacked scientific confirmation. The variety gained international prominence around 2014, when it began appearing in Cup of Excellence competitions, yet it remained relatively obscure compared to other trendy varieties like Pink Bourbon due to the geographic isolation of its primary growing region in Urrao, Antioquia.

Recent scientific inquiry has fundamentally shifted the understanding of this plant. A 2024 study published in the Journal of Plant Biochemistry and Biotechnology analyzed the chloroplast genomes of these plants, providing a more accurate picture of their lineage. Contrary to the long-held belief that it was merely a Caturra mutation, evidence now suggests that the Chiroso lineage possesses genetic roots tracing back to Ethiopian landraces. This discovery explains the variety's distinct sensory profile, which often deviates significantly from the standard expectations of traditional Caturra or Bourbon cultivars.

In the field, the plant is noted for its unique morphology. The 'Caturra Chiroso' subtype is physically smaller than its Bourbon Chiroso counterpart, reflecting the compact growth habit that makes it manageable for smallholder farmers. Despite its high quality, it requires careful agronomic management, as many Arabica varieties with similar profiles are susceptible to common coffee diseases such as leaf rust. Producers choose to cultivate it primarily because of the premium prices it commands in the specialty market, driven by its reputation for exceptional cup quality.

From a sensory perspective, Caturra Chiroso is highly prized by roasters and baristas for its complexity. It is frequently described as having a vibrant, aromatic profile that features bright acidity, floral notes—often compared to jasmine or orange blossom—and citrus or lemongrass undertones. This cup profile is markedly different from the balanced, sweet, and nutty notes typically associated with standard Caturra, offering a tea-like elegance that performs exceptionally well in both washed and experimental anaerobic natural processes.

Today, the industry is moving toward using the simpler name 'Chiroso' to avoid the confusion caused by the historical reliance on phenotypic naming conventions. As more research emerges, the variety is increasingly recognized not as a simple mutation, but as a distinct, high-value cultivar with a unique genetic history. For the producer, it represents a high-quality niche product; for the roaster, it is a sought-after competition-grade coffee; and for the consumer, it serves as a prime example of the hidden genetic diversity still being uncovered within Colombia’s coffee-growing regions.
