D17 (D212 / Kopi / Coffee / Chiat Chi / S17 / Lao Tai Po)

D17 (D212 / S17 / Kopi / Coffee / Chiat Chi / Lao Tai Po) has a reputation that is almost bigger than the fruit itself. Among bitter-durian drinkers and old-school orchard regulars, this is the clone people bring up when they want something with a real edge. The nickname "Kopi" is not marketing fluff either. The aftertaste really does lean toward roasted coffee, burnt sugar, and dark cocoa rather than simple sweetness.

What People Notice First

The flesh usually comes in a pale yellow tone and looks modest compared with brighter, flashier clones. Once it hits the mouth, though, the texture immediately separates it from wetter durians. D17 is often described as creamy but slightly dry, almost powdery at the finish, which makes each bite feel concentrated instead of loose.

Regular buyers often say this is the kind of durian that wakes up the palate rather than coats it in sugar. The bitterness arrives early, then stretches out into a roasted, espresso-like finish.

Flavor Insight

Good D17 tends to move in layers: first a firm bitter hit, then dark chocolate, then a faint sweetness that appears late rather than upfront. That delayed sweetness is part of why dedicated fans keep chasing it. It feels serious, mature, and slightly stern compared with beginner-friendly varieties.

If Musang King is the polished modern celebrity, D17 often feels like the uncompromising elder with more bite and less charm. That is exactly why some durian hunters prefer it.

Who Usually Likes It

This variety suits eaters who already know they enjoy bitterness and are not looking for a custardy dessert profile. It is commonly sought at specialty farms around Balik Pulau and older stalls in George Town where experienced sellers can point out fruits with the right maturity and depth.

Note: It's famous for a distinct bitter aftertaste that mimics dark coffee. It is also widely known as S17 and is officially registered as D212.
