Yemen Arabian Mocca Coffee at One Great Coffee. Grown in southern Yemen in a mountainous region with elevations in excess of 4,500 feet, Yemen Arabian Mocca is one of the world's oldest cultivated coffees. It is distinguished by its richness, full-body, and chocolaty undertones, which have become synonymous with "mocha" flavor. Arabia Mocca is nurtured by the rich soils of the mountain terraces. Hand-harvested and naturally dried, Yemen Arabian Mocca has a well-refined taste and balanced flavor. With earthy undertones paired with citrusy notes, this gourmet coffee is a true indulgence.
