Tenom Coffee is a big deal in Sabah. The beans come from the Tenom valley, wok-roasted by Yit Foh, and the result is a thick, aromatic robusta with a smoky depth that tastes nothing like your generic instant stuff. If you have never had it, think strong kopitiam kopi but with more character. The calorie numbers here are honest estimates, bah, because there is no hard nutrition data published for this specific coffee, so treat them as ballpark figures based on the ingredients. For the standard kopi putih with condensed milk, 130 calories sounds modest but it adds up fast if you drink two or three a day.
What actually drives the calories is straightforward: condensed milk, full stop. That 28g of condensed milk alone is 90 calories. The brewed coffee itself is basically 5 calories. So if you switch from kopi putih to kopi C (evaporated milk plus sugar), you drop from 130 to about 90 calories per cup. Go kopi O with sugar and you are at 65 calories. Go kopi O kosong and you are at 5. Three cups of kopi putih a day is 390 calories before you have eaten a single thing. Three cups of kopi O kosong is 15 calories. That is the whole game right there.
