Hunan fermented rice wine (湖南甜酒酿, hu nan tian jiu jiang) is a traditional sweet fermented rice dish that has been a part of Hunan food culture for centuries. Glutinous rice is cooked, cooled, and inoculated with a special fermentation starter (酒曲, jiu qu) that contains the molds and yeasts needed to convert the rice starches into sugars and alcohol. After two days of fermentation at room temperature, the rice becomes sweet, fragrant, and slightly alcoholic, with a puddling-like texture and a clear, sweet liquid (米酒, mi jiu) pooling around it. In Hunan, this sweet fermented rice is served warm, often with a poached egg and a sprinkle of osmanthus flowers or goji berries. It is a comforting, nourishing treat that is especially popular in winter and is believed to warm the body and aid digestion.
Fermented rice wine (酒酿, jiu niang or 甜酒酿, tian jiu jiang) is one of the oldest fermented foods in China, with a history dating back over 4,000 years. In Hunan, it is a deeply rooted home cooking tradition — almost every family has a jar of fermenting rice in the kitchen during the cooler months. The fermentation starter (酒曲, jiu qu) is a ball of ground grains mixed with molds (primarily Rhizopus) and yeasts that work together to break down the rice starches into sugars and then into alcohol. The result is a sweet, mildly alcoholic rice that can be eaten on its own, cooked with eggs, or used as an ingredient in other dishes. In Hunan culture, sweet fermented rice is considered nourishing for new mothers, the elderly, and anyone recovering from illness. It is also a popular winter comfort food, served warm on cold evenings.
Ingredients
The key ingredient is the fermentation starter (酒曲, jiu qu), which can be found at Chinese grocery stores, usually in small white balls. Glutinous rice (糯米, nuo mi) is essential — regular rice will not ferment properly. All equipment must be clean and oil-free.
- 500 g glutinous rice (糯米, nuo mi)
- 1 fermentation starter ball (酒曲, jiu qu), about 4 g
- 500 ml water for cooking rice
- 100 ml cooled boiled water for fermentation
- 2 eggs (for serving)
- 1 tbsp goji berries (for serving)
- 1 tsp dried osmanthus flowers (for serving)
- 2 tbsp sugar (for serving, optional)
- 3 slices fresh ginger (for serving)
- 1 tbsp dried longan (for serving)
- Clean glass jar with lid (for fermentation)
Step-by-Step Instructions
- Cook the glutinous rice. Rinse the glutinous rice thoroughly under cold water until the water runs clear. Soak the rice in water for 4 to 6 hours, or overnight, until the grains are easily crushed between your fingers. Drain the rice and transfer it to a steamer basket lined with cheesecloth. Steam over high heat for 30 to 40 minutes until the rice is fully cooked and translucent. Alternatively, you can cook the rice in a rice cooker with slightly less water than usual — the rice should be cooked but firm, not mushy. Once cooked, spread the rice on a clean tray to cool to about 30°C (lukewarm — warm to the touch but not hot). This temperature is critical — too hot will kill the fermentation cultures, too cold will slow down fermentation.
- Prepare the fermentation starter. Crush the fermentation starter ball (酒曲, jiu qu) into a fine powder using a mortar and pestle, or place it in a plastic bag and crush it with a rolling pin. The starter contains the molds and yeasts that will convert the rice starches into sugars and alcohol. Make sure all your equipment — the jar, your hands, the spoon — is clean and completely oil-free. Even a trace of oil can inhibit fermentation. Dissolve about half of the crushed starter powder in 100 ml of cooled boiled water. This liquid will be used to moisten the rice and distribute the starter evenly.
- Mix and ferment. Once the cooked rice has cooled to lukewarm (about 30°C), transfer it to the clean glass jar. Sprinkle the remaining dry starter powder over the rice and pour in the starter-water mixture. Mix gently but thoroughly with a clean spoon, making sure every grain of rice is coated. Press the rice down gently and make a small well in the center — this well allows you to monitor the fermentation progress, as sweet liquid (米酒, mi jiu) will pool in it. Cover the jar with a clean cloth or loose lid — do not seal tightly, as the fermentation produces gas. Place the jar in a warm spot (25-30°C) and let it ferment for 36 to 48 hours. Check it after 24 hours — you should see liquid pooling in the well and smell a sweet, wine-like aroma.
- Check and store. After 36 to 48 hours, the fermentation should be complete. The rice will have become soft and sweet, with a clear, fragrant liquid pooling in the center well. Taste it — it should be sweet with a mild alcoholic kick. If it is not sweet enough, let it ferment for a few more hours. If it tastes too alcoholic or sour, it has fermented too long. Once it reaches the desired sweetness, transfer the jar to the refrigerator to stop the fermentation. The fermented rice will keep in the refrigerator for 1 to 2 weeks. The flavor will continue to develop slowly even in the refrigerator, becoming more alcoholic over time, so it is best consumed within the first week.
- Serve warm with egg. To serve, scoop 3 to 4 tablespoons of the fermented rice into a small saucepan. Add about 200 ml of water and bring to a gentle simmer. Crack an egg into the simmering liquid and poach it for 2 to 3 minutes until the white is set but the yolk is still runny. Add goji berries and a little sugar if desired. Ladle into a bowl and sprinkle with dried osmanthus flowers. The warm, sweet, fragrant broth with the silky poached egg and soft fermented rice is incredibly comforting — it is the quintessential Hunan winter treat. Serve it as a dessert, a bedtime snack, or a nourishing breakfast on a cold morning. The gentle warmth and natural sweetness make it deeply soothing.
- Keep everything clean and oil-free. Even a tiny amount of oil or soap residue can inhibit fermentation. Sterilize the jar with boiling water before use.
- Temperature is critical. The rice must be cooled to lukewarm (about 30°C) before adding the starter. Too hot kills the cultures; too cold slows fermentation.
- Do not seal the jar tightly. Fermentation produces gas. A loose lid or cloth cover allows gas to escape while keeping out contaminants.
- Check after 24 hours. If you see liquid pooling in the well and smell a sweet aroma, fermentation is on track. If not, move the jar to a warmer spot.
