Volcán Azul
Alejo Castro Kahle is the heart and soul of Volcán Azul, a world-renowned coffee estate in Costa Rica's volcanic highlands. As a fifth-generation coffee farmer, he masterfully blends tradition with innovation, making sustainability and quality the cornerstones of his craft.
The story begins in the mid-19th century when two European families pioneered coffee businesses in the Americas: the Spanish Castro-Jimenez family in Costa Rica and the German Kahle family in Mexico's Chiapas region. Today, Alejo represents the fifth generation of the Castro-Kahle family, continuing their century-old legacy of coffee cultivation on the slopes of Poás Volcano in central Costa Rica.
Volcán Azul encompasses three farms—two in the Central and West valleys and one near Tarrazú—along with a milling facility. Under Alejo's leadership, the team focuses intensively on coffee quality and consistency. Research into coffee varieties is paramount, especially as Costa Rica faces climate change challenges. Coffee plants, being naturally delicate, are particularly vulnerable to weather extremes and climate shifts. These conditions can trigger diseases like coffee leaf rust—a challenge Alejo has faced firsthand, along with many other Central American producers.
For the Castro-Kahle family, coffee transcends mere specialty—it's a cherished tradition.
For the Castro-Kahle family, coffee transcends mere specialty—it's a cherished tradition. Their farms nurture diverse varieties, including Caturra, Catuai, Geisha, SL28, Villasarchi, Sarchimor, Obata, San Isidro, and Venecia.
At Volcán Azul, sustainable farming and biodiversity conservation take centre stage. Rather than using insecticides, the farms rely on bees, which also produce honey from coffee blossoms. Alejo pioneers complementary planting techniques, introducing specific grasses that both prevent erosion and provide alternative food sources for root-feeding insects. Moreover, the family's commitment to conservation extends beyond their coffee farms—they've preserved 200 hectares of forest above their farms and acquired 1,500 hectares of primary forest in southern Costa Rica's Osa Peninsula.
