Palm sap fermented into a sour cloudy wine and drunk from bamboo cups. It is central to Batak and Toraja social life, where tuak houses serve as village meeting places, and it is tapped daily from coconut, sugar or lontar palms.
It ferments on the tree before anyone handles it, production of alcohol is licensed almost everywhere, and the raru bark that shapes the Batak version is gathered wild.
What goes into it
- palm sap
- raru bark, in the Batak version
- nothing else
How it is made
A tapper cuts the flower stem of the palm and hangs a container to collect the sap, returning twice daily. It ferments in the container on wild yeasts. Batak tappers add pieces of raru bark, which both bitters the drink and slows the fermentation so it keeps a day longer than it otherwise would.
How long it takes: hours to a day; sour quickly
How it is eaten
From a bamboo cup or a glass at a lapo tuak, with grilled pork or fish.
