Dugyeonju (Azalea Blossom Rice Wine)

Ingredients

Equipment Needed

• •5 to 6 liter sanitized onggi or wide-mouth glass fermentation jar
• •Clean cotton cloth and rubber band, or fermentation airlock lid
• •Large steamer with cotton steaming cloth
• •Instant-read thermometer
• •Fine mesh strainer plus brew bag or cheesecloth
• •Sanitized bottles, preferably pressure-safe
• •pH strips, optional but useful

Instructions

1. 1

   Clean the blossoms

   Use only food-grade edible Korean azalea petals, jindallae (Rhododendron mucronulatum). Do not use florist azaleas, ornamental rhododendrons, roadside flowers, or cheoljjuk (royal azalea). Pull away every stamen, pistil, green calyx, and stem, because the petals are the part wanted here and the rest brings bitterness and risk. Rinse the petals quickly in two bowls of cool water, lifting them out so grit stays behind, then dry them on a clean towel for 30 minutes. Damp petals dilute the mash and make sourness easier.

   You may need 5 to 6 loosely packed cups of whole fresh blossoms to end with 90 g cleaned petals. If using food-grade dried petals, use 18 g and do not rinse unless dusty.
2. 2

   Soak the rice

   Rinse the glutinous rice in 6 or 7 changes of cool water, rubbing it gently between your palms, until the water runs mostly clear. Soak it in fresh cool water for 8 hours, then drain in a colander for 1 hour. This is not empty waiting. The soak carries water to the center of the grain so the rice steams firm and even, not hard in the middle and sticky outside.

3. 3

   Steam firm rice

   Line a steamer with a wet cotton cloth and spread the drained rice evenly. Steam over steady high heat for 45 to 50 minutes. After 30 minutes, sprinkle about 120 ml boiling water over the rice and turn it once with a rice paddle, then finish steaming. The rice should be translucent and cooked through, but the grains should still hold their shape. This is godubap (firm steamed rice), and it gives nuruk something to work on without turning the jar into paste.

4. 4

   Cool the rice

   Spread the steamed rice on a sanitized tray or wide bowl and let it cool to 25 to 28 C. Turn it once or twice so the heat leaves evenly. Hot rice kills the yeasts in the nuruk and bruises the flowers. If you do not have a thermometer, press a clean hand into the rice; it should feel just warm, never hot.

5. 5

   Wake the nuruk

   Crumble the nuruk very fine, sifting out any hard pebbles. Stir it into the 1.5 liters cooled boiled water in a sanitized bowl and let it sit for 20 minutes. Nuruk is not just flavor. Its enzymes change rice starch into sugar, and its yeasts change that sugar into alcohol, so it has to touch the rice evenly.

6. 6

   Layer the jar

   Sanitize a 5 to 6 liter onggi or wide-mouth glass jar. Layer one-third of the cooled rice, one-third of the nuruk water, and one-third of the cleaned petals. Repeat twice more. With a sanitized hand or spoon, lift and turn the mash for 1 minute so the nuruk reaches the rice, but do not crush the petals into paste. Leave generous headspace, at least one-third of the jar empty, then cover with a cloth and rubber band or a fermentation airlock. Never seal active rice wine tightly.

7. 7

   Start fermentation

   Keep the jar at 20 to 22 C for the first 3 days. Stir twice a day on days 1 and 2, then once on day 3, always with a sanitized spoon. The rice will rise, bubbles will appear, and the smell should be grainy, lightly sweet, and floral with a clean sour edge. Stirring early keeps the top from drying out and helps the nuruk work through the rice.

   White nuruk flecks are normal. Fuzzy mold, black, orange, red, or green growth, or a rotten smell means the batch is not worth saving. Throw it out and clean the vessel properly before trying again.
8. 8

   Let it finish

   After day 3, move the jar to 18 to 20 C and leave it mostly alone. If rice floats above the liquid, press it down gently with a sanitized spoon. Begin tasting on day 10. The wine is ready to strain between days 12 and 14, when bubbling has slowed, the rice grains have softened and begun to sink, and the liquid tastes lightly sweet, cleanly alcoholic, and floral without raw rice flavor. 손맛 is real. I still measure it, so it can be handed on.

9. 9

   Strain gently

   Pour the mash through a sanitized brew bag or cheesecloth-lined strainer set over a clean bowl. Let it drain for 1 hour, then press only lightly. Hard squeezing pulls harshness from the nuruk and bitterness from the spent petals. For dugyeonju, you want the clearer yakju (clear rice wine) portion, not a heavy cloudy takju.

10. 10

    Settle and bottle

    Cover the strained wine and refrigerate it for 24 hours so sediment drops to the bottom. Pour or siphon the clear upper wine into sanitized bottles, leaving 2 cm headspace. Keep refrigerated and vent the bottles once a day for the first 3 days, because fermentation can continue and pressure can build. The wine is drinkable now, but 3 to 7 days of cold rest rounds the grain flavor.

11. 11

    Serve chilled

    Pour the chilled dugyeonju into small cups without shaking up the sediment. If you reserved safe cleaned petals, float one or two on each cup, petals only. The wine should be pale straw with a faint blush, lightly floral, and still clearly a rice wine. Serve it with mild jeon (pan-fried cakes), fresh pear, or simple rice sweets, not with food so spicy that the flower disappears.

Chef Tips

• •The flower is the safety issue. Jindallae is the edible azalea used for this drink; many ornamental azaleas and rhododendrons are poisonous. If you cannot identify the flower with certainty or buy it as food, do not brew with it.
• •Nuruk changes from maker to maker. Good nuruk smells grainy, nutty, and faintly mushroomy. If it smells chemical, rotten, or sharply musty before it ever touches the rice, send it back without a speech.
• •Temperature writes the flavor. Above 24 C, the mash can turn harsh and sour before the rice has given itself up. Below 16 C, it may stall. A steady 20 to 22 C for the first days, then a little cooler, is the clean path.
• •The safe shortcut is the vessel: a sanitized glass jar with an airlock works in place of onggi. The unsafe shortcuts are unclean flowers, hot rice, and an airtight lid during active fermentation.
• •For a clearer drink, strain gently and let the wine settle cold before bottling. If you want the cloudy lees, dilute and strain them separately as takju, but do not call that first cloudy pressing dugyeonju.

Advance Preparation

• •Begin 2 to 3 weeks before you plan to serve. The active work is mostly on the first day, but the wine needs about 12 to 14 days to ferment and at least 24 hours to settle cold.
• •Fresh petals are best cleaned the day they are picked and used the same day. For longer keeping, dry food-safe cleaned petals in one layer in shade until brittle, then store airtight in the freezer and use 18 g dried petals for this batch.
• •The rice can be washed and soaked overnight. Do not steam it ahead and refrigerate it, because cold rice firms unevenly and does not ferment as cleanly.
• •Finished dugyeonju keeps refrigerated for about 4 weeks. Vent bottles during the first few days, and discard any bottle that smells rotten, grows mold, or gushes violently.
