Tuak is the traditional rice wine of Borneo — but “rice wine” covers a whole family of drinks across Asia, and they are not interchangeable. The short answer: tuak is fermented with ragi (a wild yeast-and-mould culture) rather than the koji mould used for sake, which makes it rustic, fruit-forward and often lightly sweet, where sake is cleaner and drier. Here is how the main rice wines compare.
How is tuak different from sake?
Sake (Japan) and tuak (Borneo) both start with rice, but the fermentation is fundamentally different. Sake uses koji (Aspergillus oryzae) to convert rice starch into sugar, in a precise, highly controlled process that produces a clean, often dry drink. Tuak uses ragi — a local culture of wild yeasts and moulds pressed into balls — fermented in jars, family by family. The result is earthier, livelier and frequently off-dry, with fruit and floral notes. Sake is also usually higher in alcohol (~15–17%) and filtered clear; rustic tuak can be cloudy.
How does tuak compare to other rice wines?
| Rice wine | Origin | Ferment culture | Typical taste | Typical ABV | Usually served |
|---|---|---|---|---|---|
| Tuak | Borneo (Sarawak) | Ragi (wild yeast + mould) | Off-dry, fruity, floral | 11–17% | Chilled or room temp |
| Sake | Japan | Koji mould | Clean, dry to umami | 15–17% | Chilled or warmed |
| Makgeolli | Korea | Nuruk starter | Sweet, tangy, fizzy, milky | 6–9% | Cold, shaken |
| Huangjiu / Shaoxing | China | Qū (wheat/rice starter) | Rich, savoury, nutty | 14–20% | Warmed |
| Brem | Bali, Indonesia | Ragi (related culture) | Sweet, reddish | 5–14% | Cold |
Tuak’s closest relative is Balinese brem — both use ragi-family cultures — while makgeolli is its milky, fizzy Korean cousin and sake the refined Japanese one.
Is tuak a wine, a beer or a spirit?
Technically it is none of them. Like sake, tuak is brewed from grain (rice), so it is closer to beer in method — but it is undistilled, so it is not a spirit, and it contains no grapes, so it is not a wine in the strict sense. “Rice wine” is simply the common English shorthand. For the full story of how it’s made, see our guide to what tuak is.
Which should I try first?
If you already enjoy sake, an aged or drier tuak will feel familiar; if you like sweeter, fruit-driven drinks, a fruit-infused tuak is the easiest way in. The real difference is character: tuak tastes of place — of Borneo’s rice, fruit and tradition. Browse our collections to find a starting bottle, or read how to serve and pair tuak once you have one.
