Geisha Inca

The term 'Geisha Inca' refers to a specific coffee lineage cultivated in the Andean highlands of Peru, most notably within the Incahuasi Cooperative. For years, producers and international buyers operated under the assumption that these plants were the same Ethiopian-origin Geisha (or Gesha) variety that gained global fame in Panama. This belief was reinforced by the coffee's striking cup profile, which often features the floral, tea-like, and citrus notes characteristic of the Geisha cultivar, as well as similar leaf and plant morphology. Because of these similarities, the name 'Inca Geisha' became a local shorthand for this high-quality, high-altitude crop.

However, the true identity of this coffee has been the subject of significant investigation by coffee historians and researchers. The consensus among experts, including detailed detective work by coffee historian Christopher Feran, is that the variety is actually SL9. SL9 was one of the many varieties developed and distributed by Scott Agricultural Laboratories (Scott Labs) in Kenya during the mid-20th century. While the variety was intended for different climates, it found a niche in the unique microclimates of Peru, where it thrived under the care of local farmers who utilized traditional agroforestry techniques.

In terms of field performance, SL9 shares several traits with other legacy varieties from the Scott Labs catalog. It is often described as a shy-bearing plant, meaning it produces lower yields compared to modern commercial hybrids. Like many older Arabica varieties, it is susceptible to common coffee diseases such as Coffee Berry Disease (CBD), which requires careful management by farmers. Despite these challenges, the quality potential of the plant is high, which has made it a prized asset for specialty-focused cooperatives in regions like the Incahuasi Valley.

For the producer, the decision to cultivate this variety is driven by its exceptional cup quality and its established reputation in the specialty market. Farmers like Albino Ibias have become synonymous with the production of this variety, working alongside their families to maintain the integrity of the crop. The transition from labeling it as 'Geisha' to 'SL9' or 'Inca Gesha' represents a broader shift in the industry toward transparency and genetic accuracy, ensuring that buyers understand exactly what they are sourcing.

For the roaster and the consumer, the cup profile of this Peruvian SL9 remains highly desirable. It frequently exhibits the delicate, perfumed aromatics—such as jasmine and bergamot—that made the Geisha variety a global sensation. This has allowed Peruvian producers to command premium prices, as the coffee consistently performs well in high-level competitions and specialty auctions, bridging the gap between the prestige of the Geisha name and the reality of the plant's unique genetic heritage.

Ultimately, the story of Geisha Inca is a testament to the complexity of coffee taxonomy and the importance of genetic verification. While the name 'Geisha' was applied as a descriptor of quality and appearance, the reality of the plant's lineage as SL9 highlights the historical influence of research stations like Scott Labs on global coffee production. Today, the coffee stands on its own merits, celebrated for its distinct Peruvian terroir and the dedication of the farmers who have preserved this specific lineage for decades.
