Oliang

[2] Oliang is prepared from a mixture of Robusta coffee grounds, brown sugar, and various grains and seeds like cardamom, corn, soybeans, rice, and sesame seeds.

[4] The name oliang is derived from the Teochew Chinese pronunciation of 烏涼 (Pe̍h-ōe-jī: o͘-liâng), which literally means "black and iced," in reference to the black iced coffee concoction.

[5] Teochews comprise the majority of the Thai Chinese population.

Traditionally, oliang is brewed with a Thai coffee filter called tungdtom (Thai: ถุงต้ม), a tea/coffee sock with a metal ring and handle to which a cotton cloth bag is attached.
