Our Story
Nestled in the highlands surrounding Lake Toba, one of the world's largest volcanic lakes, our community of farmers has been cultivating exceptional Arabica coffee for generations. The volcanic soil, high altitude, and unique microclimate create ideal conditions for specialty-grade beans.
Through our partnership with Seedlot, these farming families have gained access to sustainable agricultural practices, fair market prices, and the tools needed to expand their operations while preserving the land that sustains them.
"USAID suddenly left. We are very happy Seedlot came along with a program to replace it."

Sustainable Practices
Our Lake Toba community practices shade-grown coffee cultivation, integrating coffee plants with native trees and companion crops. This biodiversity-rich approach mimics natural forest ecosystems, creating resilient farms that benefit both the environment and crop quality.
What We Grow
Heritage Varietal
The original Arabica. Clean, sweet cup with subtle complexity. Grown at 1,200-1,400m in volcanic soil, producing delicate floral and citrus notes.
Local Specialty
Indigenous to North Sumatra. Full-bodied with earthy, herbal notes and a heavy syrupy mouthfeel. The signature Mandheling profile.
Disease Resistant
Modern hybrid bred for leaf rust resistance without sacrificing cup quality. Bright acidity with chocolate and stone fruit notes.
