Neftalí Castro and El Diamante
This remarkable lot comes from El Diamante, a 30-hectare family-run farm near Cajamarca in Tolima, Colombia. It's owned and operated by Neftalí Castro and his sisters, who are the third generation to steward the land. Neftalí returned to the farm in 2008, after years working as a mechanic in Ibagué, and immediately set his sights on specialty coffee.
Inspired by a visit to Pitalito, he saw the potential of coffee as both a source of income and social impact. He expanded coffee cultivation on the farm, planted eight hectares of Caturra, built a small wet mill, and began to refine his processing methods. His efforts quickly gained recognition — he placed 29th in the Cup of Excellence in 2009 and rose to 3rd place just two years later.
Following some difficult seasons after planting Castillo (which underperformed in the farm's cool climate), Neftalí made the bold move to replace it with Tabi — a rust-resistant hybrid better suited to high elevations. The results were encouraging, and he has since expanded the farm with newer plantings of Pink Bourbon, Chiroso, Gesha, and a promising mystery cultivar he calls 'Kenya Bourbon' (nicknamed "the Ferrari").
This lot is 100% Pink Bourbon, a variety known for its florals, elegant acidity and layered complexity.
About the Farm
While eight hectares are planted with coffee, the steep terrain means trees are spaced wider than usual (2m x 2m), resulting in a planting density more typical of a five-hectare farm. The coffee is shade-grown under guamo trees, which support a healthy ecosystem including native species like guatín and lapa.
El Diamante is more than just a coffee farm — it's a source of inspiration in the community. Neftalí is widely respected as a leader and mentor to other producers. His passion, curiosity and resilience have helped build a reputation for quality that extends well beyond his region. "Coffee is my passion," he says. "I don't want to do anything else."
Processing Details
This lot was selectively hand-harvested and processed on-site using the washed method at El Diamante's micro-mill. After pulping with a manual device, the coffee underwent extended fermentation for 48–72 hours in cool climate conditions. The lower ambient temperatures allowed multiple days' worth of cherries to be added to the same tank, with fresh mucilage helping regulate pH and slowing the process to bring out vivid, winey acidity.
Once fermentation was complete, the coffee was washed with clean water from nearby rivers and then dried for 10–18 days on parabolic beds — greenhouse-like structures designed to control airflow and temperature while protecting the coffee from rain and condensation. Once fully dried, the coffee was rested in parchment before being prepared for export.
About Cajamarca & Tolima
Cajamarca, which means "Cold Lands" in Quechua, is a mountainous area rich in volcanic soils thanks to nearby Cerro Machín. The region's fresh water sources and lush biodiversity make it an ideal environment for both agriculture and specialty coffee production.
Farming here follows traditional practices — selective hand-picking, minimal use of agrochemicals, and organic-style management. Many of the farms grow a mix of Caturra and Tabi, with some experimenting with newer varietals. The region has also stood strong against threats from gold mining interests, with communities defending their farmland and prioritising sustainable agriculture.
Tolima as a whole is one of Colombia's most exciting regions for specialty coffee, despite being relatively underexplored due to historic inaccessibility. Years of conflict made the area difficult to reach, but since 2012, peace efforts have allowed stunning coffees from the region's mountains to finally reach international buyers. With its elevations, microclimates and passionate producers like Neftalí, it's easy to see why interest in Tolima's coffees continues to grow.
