A high-humidity climate, volcanic soil, and dated ancient processing methods make Sumatra one of the most satisfying coffees. It has historically been underrated. Sumatran coffee was once sold as Javan, and the best Javan grade at that. Most of the finest Mocha-Java blends were likely Sumatran coffee as well. Mandheling and Lintong are two famous districts. The original vintage Sumatra taste depends on dry processing, though some wet processed coffees have the same profile.
