Red Durian (Durio Graveolens) Red Durian or in local terms “Duyan”. This type of durian is for the indigenous people of North Kalimantan, especially the Tidung and Dayak tribes. This durian is very interesting because of the color variations in the flesh of the fruit, the thorn is quite long and the fruit does not issue a strong aroma like durian in general. It tastes good, sweet and not too runny, unlike durian in general, red durian has a fresh, fluffier, creamy meat. That is one of the reasons for this type of durian is not commercial like other durian in general. However, red durian can only be obtained at certain times with a harvest cycle every 5 years because the duyan tree is only left to grow naturally and organic in the forest without the maintenance of human intervention.
