Coffea arabica var. n39

What is Coffea arabica var. n39? It is a specific coffee variety selected and developed in Tanzania, often associated with the research efforts of the Tanzania Coffee Research Institute (TaCRI). Like the famous SL series in Kenya, the N-series selections were designed to improve the quality and yield of coffee grown in the unique volcanic soils of Tanzania's mountain regions, such as the slopes of Mount Kilimanjaro and Mount Meru.

Coffee N39 is highly regarded for its sensory characteristics. It is known for producing a cup that is bright, clean, and complex, often featuring notes of citrus, berries, and a wine-like acidity that is characteristic of high-quality East African coffees. Because it was selected for its performance in these specific high-altitude environments, it is able to fully express the terroir of the region, resulting in a cup that is both distinct and memorable.

Agronomically, N39 is valued for its balance of yield and quality. While it is not as widely known globally as the Bourbon or Typica varieties, it is a staple for Tanzanian farmers who rely on its consistent performance. It is well-suited to the traditional washing stations that process the majority of Tanzania's specialty coffee, where the focus is on preserving the delicate, nuanced flavors of the bean.

In practice, N39 is often found in lots labeled as 'Tanzania AA' or 'Tanzania Peaberry.' For roasters, this variety is a delight to work with, as it responds well to a variety of roast levels, though it is most often roasted to a light or medium level to highlight its vibrant acidity. It represents the success of regional agricultural research in creating varieties that are perfectly suited to their environment, providing a high-quality product that stands out in the competitive global specialty coffee market.
