The most popular coffee brewing method in Malaysia and Singapore for Kopi and Kopi O is the use of a the muslin coffee sock. Ground Kopi is added to the coffee sock. Boiling hot water is poured over the aromatic coffee grounds, which are then stirred using a long wooden stick.
Variations include adding coffee grounds to the coffee sock and brewing the coffee and then removing the sock.

Condensed milk is added, 2 or 3 tablespoons for Kopi but not Kopi O.
