Speak tuak
A glossary of tuak terms
The words you’ll meet around Borneo’s rice wine — from ragi to gula apong — explained simply.
- Tuak
- The traditional rice wine of Borneo, fermented from glutinous rice, ragi and sugar; central to Dayak celebration and the Gawai festival.
- Ragi
- The starter culture used to ferment tuak — pressed balls of wild yeasts and moulds native to Borneo. Ragi (rather than Japanese koji) gives tuak its rustic, fruity character.
- Tapai
- The fermented rice mash produced during tuak-making; the alcoholic liquid is separated from it and finished with sugar. Tapai is also eaten as a sweet fermented snack.
- Pulut
- Glutinous (sticky) rice — the base grain for tuak. Its high starch content feeds fermentation.
- Gula apong
- Sarawak’s smoky palm sugar, tapped from the nipah palm, often used to sweeten and flavour tuak.
- Apong
- The nipah palm whose sap yields gula apong; also lends its name to tuak expressions such as Apong Ember.
- Ang kak
- Red yeast rice from Foochow Chinese tradition (rice fermented with Monascus purpureus). It gives tuak merah its ruby colour and deeper, savoury character.
- Tuak merah
- Literally “red tuak” — a Sarawakian rice wine coloured and enriched with red yeast rice, blending Dayak and Foochow traditions.
- Gawai Dayak
- The Dayak harvest festival of Sarawak, celebrated on 1 June, at which tuak is poured in welcome and thanksgiving.
- Langkau
- A distilled spirit made from tuak — much stronger (40%+ ABV). Distinct from tuak itself, which is undistilled.
- ABV
- Alcohol by volume — the measure of a drink’s strength. Tuak is typically 11–17% ABV, similar to wine.
- Vintage
- The date a batch of tuak was made. Because tuak is small-batch and best enjoyed fresh, Tuak Atelier prints a vintage on every bottle.
- Dayak
- The collective term for the indigenous peoples of Borneo — including the Iban, Bidayuh and Orang Ulu — whose traditions gave rise to tuak.
- WAT
- The social enterprise (Work and Training) behind Tuak Atelier, which trains and empowers marginalised Bornean youth.
