These are the two durians people compare when they are choosing between the best of the crop, and the choice is genuinely a matter of taste rather than quality. One is bittersweet and assertive. The other is sweeter, creamier and much easier to sit next to.
Both are also checked at the base of the fruit rather than the husk, but for different marks, and that is where most money goes wrong.
What each one actually is
Musang King is D197, registered with Malaysia’s Department of Agriculture on 9 December 1993. The register records it as coming from Tanah Merah in Kelantan, though Raub and Bentong in Pahang are where the best of it is grown. In Malay it is Raja Kunyit, the turmeric king, and in Mandarin Mao Shan Wang.
Black Thorn is D200, the highest clone number among the premium Malaysian durians, from Kampung Lima Kongsi in Sungai Bakap, Seberang Perai, Penang. Its registration year is widely quoted as 2016, but the Department’s published clone package records no date, so we do not state one. It won the 2022 World Durian Championship.
So one is a Kelantan clone grown in Pahang, the other a Penang clone. They are not variations of each other.
Telling them apart before it is opened
Musang King: look for the star. The fruit is medium sized, oval to ellipsoid, with a vivid light green to olive husk and thick, short, sharp triangular thorns spaced evenly apart. The signature is at the base: a pronounced five-pointed star where the seams meet. A clear, even star is the single most reliable external marker.
Black Thorn: look for the flower remnant. The fruit is obovate, plump and rounded, wider at the top and narrowing to a short squat stem, with prominent seams that can make it look almost pumpkin-like. Its thorns are short, densely packed and sharply pointed, often noticeably dark near the stem end. Those dark thorns are not what names it. Turn the fruit over: a genuine Black Thorn carries a small dried black flower remnant in the slightly concave base, opposite the stem. If it has broken off there may still be a dark lump or indent.
If a seller points only at dark thorns on the husk, ask to see the base.
Flavour, and the real reason to pick one
Musang King is thick and pasty, closer to a dense custard than a fruit, with very little fibre. The flavour is deep sweetness with a pronounced bitter undertone running beneath it, and notes people read as caramel, almond, vanilla or coffee. The bitterness is not a defect. It is the point, and it is what separates Musang King from the sweeter clones. The aroma is assertive.
Black Thorn is extraordinarily creamy, thick and moist, with almost no fibre, closer to velvet custard or dense ice cream. It starts with intense sweetness and then develops a mild bitterness that adds complexity without becoming harsh. Some people find wine-like notes, sometimes with a whiskey-like undertone. Its aroma is noticeably less pungent than Musang King.
That last point decides it for a lot of people. If someone in the house cannot tolerate the smell, Black Thorn is the easier fruit to bring home.
Flesh and seeds
Musang King flesh is bright golden yellow, the colour of turmeric, deeper than almost anything else on the stall. Seeds run small to medium, with roughly 40% small and flat, so the flesh to seed ratio is high.
Black Thorn flesh is pale golden yellow with an orange tinge, sometimes deep orange or reddish gold, with darker flesh generally indicating an older tree. Seeds are small to medium and elliptic, with roughly 40% often empty, which again gives a lot of flesh for the weight.
Both are good on yield. Neither is the reason to choose one over the other.
Price, and the trap in each
Black Thorn can command more than Musang King, because its scarcity is genuine rather than a name applied to an old common variety.
The Musang King trap is the label. “Old tree”, “black gold” and King of King are seller’s terms that no standard defines. They are not lies, but there is no written specification behind them and two stalls need not mean the same thing.
The Black Thorn trap is ripeness, and it is easy to miss because the fruit feels right. A Black Thorn can be soft and still be unripe. It gives under a thumb much as a ripe Musang King does, while the flesh is pale, raw-tasting and not creamy, which is the one quality the variety is bought for. Judge it on colour and texture, not softness.

Who should buy which
Buy Musang King if bitterness is what you want from durian, if you like a fruit with an argument in it, and if the smell is not a problem where you are eating it.
Buy Black Thorn if you want the creamiest, sweetest version of a premium durian, if a heavy aroma is a problem, or if you are introducing someone who has not enjoyed durian before.
If you are buying for a kitchen rather than a table, neither premium is worth paying: grade and variety price shape, size and appearance, and none of that survives the blender.
