What are the main coffee-growing regions in Indonesia?

Indonesia's main coffee regions include Sumatra (Mandheling, Lintong, Gayo), Java, Sulawesi (Toraja), Bali (Kintamani), Flores (Bajawa), and Papua. Each region produces beans with distinct flavour profiles due to differences in altitude, soil composition, and processing methods.

What is the difference between Indonesian Arabica and Robusta?

Indonesian Arabica is grown at higher altitudes (1000-1500m) and offers complex, nuanced flavours. Robusta is grown at lower elevations, produces a stronger, more bitter cup, and has nearly double the caffeine content. Indonesia is the world's largest Robusta producer and third-largest Arabica producer.

What does wet-hulled processing mean for Indonesian coffee?

Wet-hulling (Giling Basah) is a processing method unique to Indonesia where the parchment is removed while the bean still has 30-35% moisture content. This creates the heavy body, low acidity, and earthy flavour profile that Indonesian coffees are known for.
