Kopi O is a strong black coffee commonly consumed in Kuala Lumpur. The 'O' in Kopi O stands for 'O kosong,' which means 'without sugar' in Malay. This traditional Malaysian coffee is brewed using a sock-like filter called a 'sock' or 'kain saring.' The coffee grounds are placed in the sock, hot water is poured over them, and the resulting brew is collected in a cup. Kopi O is known for its bold and robust flavor, and is often enjoyed with a side of traditional Malaysian breakfast dishes like roti canai or nasi lemak.
