How to brew makgeolli beer at home is a question that rewards any homebrewer willing to step outside the Western brewing framework. Unlike any beer in the European tradition, makgeolli uses nuruk — a fermentation cake containing mold, wild yeast, and bacteria — as its sole agent for both saccharification and fermentation. There is no malting, no separate yeast pitch, no hop boil: you steam rice, mix it with nuruk and water, and let the ancient biology do everything. The process is surprisingly approachable, and most homebrewers can produce their first batch in 7–14 days from start to first taste, with a fully mature product in 2–3 weeks.

Ingredients
Rice
- Short-grain glutinous rice (chapssal / sweet rice): 1.0 kg (2.2 lb) — Koda Farms Kokuho Rose short-grain rice (affiliate link) or Korean chapssal glutinous rice from an Asian grocery. Short-grain varieties provide the starchy sweetness and silky mouthfeel characteristic of traditional makgeolli. If unavailable, non-glutinous short-grain japonica rice works well. Long-grain varieties such as jasmine or basmati are not recommended — their lower amylopectin content produces a thinner, drier result.
Sourcing tip: Korean chapssal (찹쌀) from a Korean grocery store or online importer produces the most authentic result. Look for brands like Choripdong or Ottogi chapssal.
Nuruk
- Nuruk fermentation cake: 100–150 g (3.5–5.3 oz) per 1 kg (2.2 lb) of rice — Haechandle Nuruk (affiliate link) or any Korean nuruk cake available from Korean grocery importers or specialty homebrew suppliers. Nuruk contains the mold species (primarily Aspergillus and Rhizopus) that break down rice starches, the wild yeasts (primarily Saccharomyces species) that convert sugars to alcohol, and the Lactobacillus bacteria that produce the characteristic mild lactic tartness. There is no substitute for nuruk in traditional makgeolli — it is the sole fermentation agent.
Sourcing note: Nuruk is increasingly available through Korean grocery stores, Korean food importers, and online retailers. Brands to look for include Haechandle (해찬들). Some specialty homebrew suppliers also stock nuruk. Nuruk can also be ordered from Korean suppliers who ship internationally.
Nuruk ratio note: 10–15% nuruk-to-rice (100–150 g per kg) is the recommended beginner range. Experienced brewers adjust between 5–20% to control fermentation speed and final character — lower ratios produce slower, cleaner fermentations; higher ratios produce faster, more complex ones.
Water
- Water: 2.0–2.5 liters (0.5–0.65 US gallons) per 1 kg (2.2 lb) rice — Use clean, filtered water or spring water with a neutral mineral profile. The water:rice ratio determines final ABV and sweetness. More water produces a lower-ABV, thinner product; less water produces a stronger, sweeter, thicker result. Start at a 2:1 water-to-rice ratio by weight and adjust in subsequent batches.
Equipment
Beyond basic food-safe fermentation equipment, makgeolli requires:
- Rice steamer or steamer basket — IMUSA Aluminum Steamer (affiliate link) or bamboo steamer. Makgeolli rice must be steamed, not boiled. Boiling introduces too much excess water and creates a starchy slurry; steaming produces firm-but-cooked grains that nuruk can penetrate and digest efficiently.
- Large fermentation vessel (onggi or food-safe crock): 3–5 liter (0.8–1.3 US gallon) capacity — Traditional onggi earthenware is ideal. A modern alternative is a wide-mouth glass jar or food-safe ceramic crock. Avoid metal containers, which can react with the lactic acid environment. An Earthborn Elements stoneware crock (affiliate link) or similar works well.
- Loose lid or cloth cover — Makgeolli ferments actively and produces CO₂; a loose lid or cloth tied over the vessel allows gas to escape without allowing contaminants in. A tight seal risks pressure buildup.
- Digital kitchen scale — OXO Good Grips digital scale (affiliate link) with at least 0.1 g precision for weighing nuruk.
- Thermometer — ThermoPro digital thermometer (affiliate link) to verify rice cooling temperature.
- Cheesecloth or muslin straining cloth — For straining finished makgeolli before serving. The “rough straining” (makgeolli) step uses cloth to remove large rice solids while leaving fine sediment and yeast in suspension.
How to Brew Makgeolli Beer: The Process Step by Step
Step 1 — Soak the Rice: Rinse the rice thoroughly in cold water until the water runs clear, then soak for 1–2 hours (glutinous chapssal) or 30 minutes (non-glutinous). Drain completely. Soaking allows the grains to absorb moisture evenly, which ensures uniform steaming. Under-soaked rice steams unevenly, leaving hard centers that nuruk cannot efficiently digest.
Step 2 — Steam the Rice: Place the soaked, drained rice in a steamer basket lined with cheesecloth. Steam over vigorously boiling water for 30–40 minutes, or until the grains are fully cooked through — translucent, sticky, and firm without being mushy. Test by squeezing a grain between two fingers; it should flatten without a hard starch center.
Why steaming matters: Boiled rice becomes waterlogged and starchy in ways that impede nuruk’s enzyme penetration. Steamed rice maintains its grain structure, giving the mold enzymes more surface area to work on and producing a cleaner, better-structured fermentation.
Step 3 — Cool the Rice: Spread the steamed rice in a thin, even layer on a clean surface (a baking tray lined with cheesecloth works well) and allow it to cool to approximately 30–35°C (86–95°F). This step is critical: nuruk added to rice above 40°C (104°F) may kill or damage the mold and yeast cultures. Below 25°C (77°F), fermentation will start sluggishly. Aim for body-warm temperature — it should feel comfortably warm on your wrist, not hot.
Step 4 — Mix in Nuruk: Transfer the cooled rice to your fermentation vessel. Add the nuruk (100–150 g / 3.5–5.3 oz per kg of rice) and mix thoroughly with clean hands or a sanitized spatula, ensuring the nuruk is evenly distributed throughout the rice mass. Traditional Korean brewers mix with bare, clean hands — the skin’s natural microbial community is considered a minor but contributing element.
Step 5 — Add Water: Pour the water (at room temperature, approximately 20–25°C / 68–77°F) over the rice-nuruk mixture and stir well to combine. The initial consistency will be thick — closer to a rice porridge than a liquid. Over the first 24–48 hours of fermentation, enzymatic activity will liquefy the mixture noticeably.
Step 6 — Cover and Ferment: Cover the vessel loosely with a cloth or a lid set slightly ajar. Place in a warm location: 25–30°C (77–86°F) is ideal for active, healthy fermentation. Lower temperatures (18–22°C / 64–72°F) will slow fermentation and produce a cleaner, less lactic product over 14–21 days. Temperatures above 32°C (90°F) accelerate fermentation significantly and may favor acetic acid bacteria, producing a vinegary off-flavor — in summer months, shorten fermentation to 5–7 days to compensate.
Stir the fermenting mixture once or twice daily for the first 3–5 days. This redistributes the nuruk, introduces a small amount of oxygen that benefits the early mold activity, and monitors fermentation progress. Active fermentation should be visible within 12–24 hours: bubbling, a rise in temperature within the vessel, and a developing sweet-sour aroma.
Why stirring matters: Unlike sealed fermenters, makgeolli ferments in a semi-open system. Daily stirring prevents the surface from drying out, redistributes enzyme activity, and prevents the formation of surface mold colonies that can produce off-flavors.
Step 7 — Monitor and Taste: Starting on day 5, taste the fermenting makgeolli daily. The flavor will evolve from sweet and starchy (days 1–3) to sweet-tart and slightly fizzy (days 5–7) to balanced and complex (days 7–14). Bottle or strain when the flavor reaches your preferred balance of sweetness and tartness. Allowing fermentation to continue past 14 days at warm temperatures typically increases acidity and reduces sweetness.
Step 8 — Strain (Makgeolli Step): When fermentation has reached your target flavor, strain the mixture through a cheesecloth-lined colander or strainer into a collection vessel. Squeeze the cloth gently to express the milky liquid while retaining large rice solids. This step is where “makgeolli” (roughly strained) gets its name — the goal is to leave fine sediment and yeast in suspension while removing fibrous grain material.
Note: If you prefer a thicker, more traditional texture, strain once through cheesecloth without pressing. For a slightly cleaner product, strain twice using a finer cloth on the second pass.
Step 9 — Cold Condition and Bottle: Transfer the strained makgeolli to clean bottles or a covered container and refrigerate for 3–7 days. Cold conditioning allows remaining yeast activity to slow, sediment to settle, and flavors to integrate. Makgeolli is a living beverage — the active yeast continues to ferment slowly even in the refrigerator, gradually building natural carbonation and increasing tartness over time.
Packaging options: Makgeolli is traditionally served directly from the fermentation vessel or ladled into bowls from a communal kettle. For bottling, use PET plastic bottles with gentle carbonation targets — the natural carbonation will build slowly in the bottle. Cap loosely initially to allow excess gas to escape, or “burp” the bottles daily for the first few days.
Step 10 — Serve: Before serving, gently invert the bottle or swirl the vessel to redistribute the sediment. This cloudy, yeast-rich sediment is integral to makgeolli — it carries much of the flavor and all of the living cultures. Serve cold or at cellar temperature (8–12°C / 46–54°F) in traditional wide bowls or simple cups.

Troubleshooting
No fermentation activity after 48 hours: The nuruk may have been added to rice that was too hot (above 40°C / 104°F), killing or damaging the cultures. Alternatively, the fermentation environment may be too cold. Move to a warmer location and check after 24 more hours. If no activity by 72 hours, add an additional 30–50 g (1–1.75 oz) of nuruk.
Excessive sourness, vinegar character: Fermentation temperature may have been too high (above 32°C / 90°F), favoring acetic acid-producing bacteria. Also occurs when fermentation extends too long at warm temperatures. Next batch: ferment cooler and taste more frequently.
Too sweet, not enough tartness or alcohol: Fermentation may have stalled due to insufficient nuruk, too-cool temperatures, or insufficient time. Stir thoroughly, move to a warmer location, and allow more time. If the problem persists, add an additional 30–50 g (1–1.75 oz) of nuruk.
Pink, orange, or black surface mold: A thin white film on the surface is normal (wild yeast). Pink, orange, black, or fuzzy surface growth indicates contamination. Remove affected surface layers and evaluate by smell — a clean, sour-rice aroma beneath is usually safe; any foul or rotten odor means discarding the batch. Keep equipment scrupulously clean and covered.
Thin, watery texture: Too much water in the recipe, or the rice was boiled rather than steamed. Reduce water to 1.5:1 water-to-rice ratio on the next batch, and ensure you’re steaming rather than boiling.
No carbonation in finished makgeolli: If bottled cold immediately after straining, the remaining yeast may be too dormant to carbonate. Allow bottles to warm to room temperature (18–20°C / 64–68°F) for 24–48 hours, then re-refrigerate.
Variations to Try
Floral makgeolli: Add 2–3 tablespoons of dried, food-grade chrysanthemum blossoms or rose petals to the fermenter on day 3–4 of fermentation. The floral aromatics infuse gently into the developing makgeolli, producing a perfumed, delicate variation that references Korean brewing traditions of seasonal, botanical additions.
Black rice makgeolli: Replace 20–30% of the white glutinous rice with black glutinous rice (heukmi). The anthocyanins in black rice produce a strikingly purple-tinted makgeolli with a slightly nuttier, earthier character and a beautiful visual contrast to the standard white.
Multi-grain makgeolli (ogokju style): Add 200 g (7 oz) of cooked barley or millet alongside the rice, steamed together and cooled. Multi-grain versions reflect Korean court brewing traditions and produce a more complex, grainy character with added textural interest.
Cinnamon and ginger makgeolli: During the final 2 days of fermentation, add a 5 cm (2 inch) piece of fresh ginger (sliced) and a cinnamon stick to the fermenter. The warming spice character integrates beautifully with makgeolli’s lactic sweetness and works particularly well in autumn or winter.
High-rice-ratio (premium) makgeolli: Reduce water to a 1:1 water-to-rice ratio and allow a full 14 days of fermentation. The resulting product is thicker, richer, higher in ABV (approaching 8–9%), and notably sweeter with a more pronounced rice character — closer to the premium craft versions emerging from Seoul’s craft scene.
Brewing makgeolli at home is an invitation to think about fermentation differently. There is no mash tun, no boil kettle, no separate yeast packet — just rice, water, nuruk, and time. Once you’ve made your first batch and tasted what living cultures can do with good grain, you may find that this ancient Korean tradition changes how you approach fermentation entirely.
