The unique natural conditions of the geographical area is the deciding factor to the peculiar characteristics of Đăk Hà coffee. The area is the contact point of the hot and cold climate streams under the influence of the Ngọc Linh range. The main topography of the area is round-top and flat-top hills of 580-650 metre high intertwining with low terrace, which is the transitioning terrain between high mountains and lower areas. The geographical area has a dense system of rivers, streams and lakes, the irrigation is varied with many large dams. The underground water is at medium-low level which helps regulating the water, suitable for the irrigation of coffee. The average total rainfall of the area is relatively high, though it is low during the blooming (January and February) and berry ripening (October and November). The temperature is stable throughout the months with the average variance is under 2OC. The humidity is low with annual average is 78 - 82%. The total hours of sunlight is high, concentrating in the dry season which accounts to 70% of a year’s hour of sunlight. Moreover, the soil has suitable physical and chemical properties for the development of coffee, which contributes to the peculiarity of coffee bearing the “Đăk Hà” GI. The cultivation and harvest procedures of the local producers in the geographical area are especially unique and also contribute to the taste of Đăk Hà coffee. Coffee berries are harvested when ripe, the harvest is done completely manually, picking each ripe berry or cluster without pulling unripe berries, leaves and twigs. The strict requirements regarding preparation, storage and processing of Đăk Hà coffee are the decide factor for the quality of the product.
