Rice lagers are the best-selling beers in the world by volume, Asahi Super Dry, Kirin Ichiban, Budweiser, and virtually every major Indian commercial lager (Kingfisher, Tuborg, Budweiser Magnum) use rice as an adjunct, and the style accounts for a significant portion of global beer consumption. I started homebrewing rice lagers after realising that the style most Indians drink regularly was one I had completely ignored in favour of craft styles, and that brewing a genuinely good version of the most popular style in Asia was a more technically interesting challenge than I had assumed.
Brewing rice lagers at home: grain bill, adjunct ratios, and techniques for the world’s most popular style
What defines a rice lager: A rice lager is a lager beer in which rice, either as flaked rice, rice syrup solids, or cooked rice, replaces a portion of the barley malt as the fermentable sugar source. Rice contributes: highly fermentable simple sugars (from its starch), minimal protein (compared to barley malt), essentially no colour or flavour, rice contribution is characteristically neutral. The result of rice adjunct: lower body (fewer dextrins from rice vs. malt), crisper finish (higher apparent attenuation from fully fermentable rice sugars), lighter colour (rice adds no colour compounds), and a clean, light flavour profile. This is the deliberate design of the style, the goal is a light, crisp, highly drinkable lager that shows no heaviness or excess malt character. Rice adjunct ratio, how much rice is correct: Most commercial rice lagers use 20–35% rice adjunct (as a percentage of total fermentables by weight). Budweiser: approximately 30–35% rice. Japanese lagers (Asahi, Kirin): approximately 20–30% rice. Indian commercial lagers: typically 20–30% rice or corn adjunct. At 20% rice: the beer has noticeably lighter body than an all-malt lager but retains some malt backbone. At 30–35% rice: the beer is very light in body, crisp, and clean, maximally drinkable but with minimal malt complexity. Above 35%: protein and nutrient content from the grain bill decreases enough that yeast health can be affected, requires additional yeast nutrients. For homebrewing: 20–25% rice is the sweet spot for a homebrewed rice lager with good drinkability without the technical complexity of very high adjunct ratios. Rice forms for homebrewing: Flaked rice: pre-gelatinised, can be added directly to the mash without cereal cooking. This is the easiest approach for homebrewers. Available from Indian homebrew importers or use standard Indian supermarket puffed rice (murmura/kurmura, puffed rice is pre-gelatinised by the puffing process and can be mashed directly without additional processing). Regular supermarket rice (raw long-grain rice) requires a cereal mash (cooking the rice separately at boiling temperature to gelatinise the starch before adding to the main mash). Rice syrup solids: 100% fermentable, added to the boil kettle, no mashing required. Bypasses the complexity of mashing rice. Available from Indian homebrew importers or from food ingredient suppliers. The downside: slightly different fermentation character than mashed rice, and higher cost per kg of fermentable. Recipe, 19 litre rice lager (homebrew): Target OG: 1.048. Target FG: 1.006–1.008. ABV: approximately 5.2%. SRM: 2–3 (very pale straw). IBU: 12–18. Grain bill: Pilsner malt: 3.2kg (80%). Flaked rice or pre-gelatinised rice: 800g (20%). Hops: Hallertau or Saaz: 15g at 60 minutes, 10g at 10 minutes. Water: very soft, neutral to slightly sulfate-forward. Indian RO water with small gypsum addition works well. Target: Ca 50–75mg/L, sulfate 50mg/L, chloride 50mg/L, bicarbonate below 50mg/L. Yeast: Saflager W-34/70 (Fermentis dry lager yeast) or Lallemand Diamond Lager. Ferment at 10–14°C. Without refrigeration: use Kveik Lutra (Lallemand Lutra), ferments clean at 20–35°C, producing a lager-like character without lager temperature requirements. Mash: 64–65°C for 60 minutes (low temperature for maximum attenuation, essential for the crisp finish). If using raw rice: cereal mash first (cook rice with 10% of the total malt addition at 70°C, heat to boiling, hold 20 minutes, add to main mash). Technique: the Kveik Lutra shortcut for Indian homebrewers: Lager fermentation at 10–14°C is impossible without refrigeration in Indian conditions (ambient 25–40°C). Kveik Lutra (Lallemand) is a Norwegian farmhouse yeast that produces exceptionally clean beer at temperatures from 20°C to 40°C, it is the closest available yeast to lager yeast character for warm-temperature fermentation. At 25–30°C with Lutra: the beer finishes clean, crisp, and without the banana/ester character typical of ale yeasts at high temperature. Not identical to a true cold-fermented lager, but indistinguishable to most tasters when fresh and well-carbonated. Fermentation time: Lutra at 30°C produces a complete fermentation in 48–72 hours (compared to 10–14 days for a lager at 10°C). This extreme speed is a genuine practical advantage for Indian homebrewers. India context: The rice lager style has direct relevance for Indian homebrewers: it uses readily available Indian ingredients (Indian supermarket puffed rice works as a rice adjunct), produces the style most Indian guests will find familiar and approachable, and can be brewed without lager temperature equipment using Kveik Lutra. A rice lager homebrew served cold at a social gathering in India is far more accessible to non-craft beer drinkers than a hop-forward IPA or a complex Belgian ale.
Common Questions
Can I use regular Indian supermarket rice for a rice lager adjunct, and does the rice variety matter?
Regular Indian supermarket rice can absolutely be used as an adjunct for a rice lager, rice is rice from a starch chemistry perspective, and the variety differences between Basmati, sona masuri, and long-grain rice are largely irrelevant for brewing purposes. What matters for brewing is the starch gelatinisation point and the processing state. Starch gelatinisation: rice starch gelatinises at 68–78°C, above the typical mash temperature of 64–68°C. This means raw rice starch does not convert efficiently in a standard mash. Solutions: Option 1, Use puffed rice (murmura): the puffing process gelatinises the rice starch. Puffed rice can be added directly to the mash like flaked rice, the starch is already available for enzymatic conversion. Available at any Indian grocery store for ₹30–₹80 per kg. This is the simplest approach. Option 2, Cereal mash raw rice: cook 800g of raw rice with 80g of pale malt (to provide enzymes) in 2 litres of water, bring to a boil, hold for 20 minutes, then add the hot cereal mash to the main mash tun. The cooking gelatinises the rice starch, making it available to the malt enzymes in the main mash. This is more labour-intensive but uses any rice variety. Option 3, Rice syrup or rice extract: add fermentable rice solids directly to the boil, no mash processing. The variety question: Basmati rice has slightly different starch composition (lower amylopectin content relative to sona masuri) but this difference is not significant for brewing, any Indian rice variety produces equivalent fermentable character. If anything, waxy/glutinous rice varieties (not common in Indian supermarkets) would produce slightly more body due to their higher amylopectin content. The cost of standard Indian supermarket rice (₹30–₹60 per kg) versus imported flaked rice from homebrew suppliers (₹200–₹400 per kg) makes the supermarket puffed rice option highly economical for homebrewing. Use murmura (puffed rice), it’s the most direct Indian equivalent of homebrewing flaked rice, and it works well.
