Indonesia is the land of rich spices and unique ingredients, and its latest coffee export that has gone global is the Es Kopi Susu Gula Aren (Iced Coffee with Palm Sugar Milk). This creamy, sweet, and simple beverage has redefined the Indonesian coffee scene, transforming from a simple street vendor drink to a highly sought-after menu item in modern coffee shops worldwide.
Why It Went Viral
The drink’s massive popularity is due to its irresistible balance:
- Sweetness from Nature: It uses Gula Aren (palm sugar), which has a deep, smoky caramel flavor, unlike the sharp sweetness of white granulated sugar.
- Creamy Texture: The use of fresh, full-cream milk (and sometimes creamier elements like evaporated milk) balances the strong Indonesian coffee blend.
- Accessibility: It’s easy to drink for everyone, not just hardened coffee drinkers, making it the perfect gateway beverage.
