Ayurvedic Beer Brewing: The Classical Sura Tradition and Its Therapeutic Uses

Vikram Desai — Sun, 12 Jul 2026 12:00:00 +0000

The first surprise is still real, but the chapter needs to be named correctly: in the Charaka Samhita, Chikitsa Sthana 24 is Madatyaya Chikitsa, the chapter on intoxication and alcohol-related disorders; Dwivraniya Chikitsa is the following chapter. What makes the Ayurvedic discussion remarkable is that fermented drink is not treated as a single blanket category of virtue or vice. It is treated as a potent substance whose effect depends on source material, preparation, age, dose, season, food, strength, disease state, dosha and mental constitution.

The classical question is therefore not simply “is alcohol good or bad?” but “for whom, in what form, in what quantity, at what time, with what food, and under whose supervision?” That conditional, clinical way of thinking is the heart of Ayurveda’s approach to madya, sura, asava and arishta.

Sura, Sauviraka, Asava and Arishta: The Classical Fermented Beverage Taxonomy

Classical Ayurveda uses madya as an umbrella category for intoxicating fermented preparations, while also distinguishing individual preparations by substrate, processing, age and clinical effect. Charaka describes wine and alcoholic preparations as generally amla in taste and post-digestive effect, ushna in potency, and capable of sharply influencing digestion, channels, ojas and the mind when used improperly.

Sura: A grain-based fermented liquor included in the classical madya-varga. Charaka describes sura as useful in selected conditions such as emaciation, suppressed urination, grahani, piles, depletion of milk or blood, and Vata disorders when used in the appropriate patient and context.
Madira, Jagala and Suramanda: Related fermented preparations and fractions with differing heaviness, dryness, heat and digestive action. Charaka’s discussion makes clear that fermented drinks were not all treated as interchangeable.
Sauviraka and Tushodaka: Sour grain ferments described as appetizing, digestive and laxative in the classical food-and-drink chapter. They belong closer to the category of sour fermented grain liquids than to modern sweet recreational drinks.
Asava: A medicinal fermented preparation usually made by soaking herbal drugs in water with sugar, jaggery or honey and allowing fermentation to occur without first preparing a decoction.
Arishta: A medicinal fermented preparation usually made from an herbal decoction combined with a fermentable sweet substance. The self-generated alcohol helps extract active principles and also acts as a preservative.
Maireya, Madhvasava and Dhatakyasava: Named fermented preparations with different classical properties. Charaka describes Maireya as sweet and heavy, Madhvasava as sharp and depleting, and Dhatakyasava as mild, dry and appetizing.

Why Fermented Beverages Were Considered Therapeutic

The therapeutic logic of classical fermented preparations rests on agni, dose, vehicle, extraction and suitability. Ayurveda does not present fermented drink as a casual daily wellness shortcut; it presents properly selected madya as a strong substance that may support digestion, appetite, nourishment or channel movement in some people, while disturbing ojas, senses and mind in others.

1. Deepana and rochana: Sushruta describes madya as sour, light, appetizing and capable of kindling hunger. Charaka also gives madya a strongly heating and penetrating profile. This is why classical use is tied to digestion and appetite, but also why excess or wrong use is considered dangerous.

2. Anupana and nourishment: Charaka describes sura as a post-meal drink for the emaciated and describes wine in carefully selected contexts such as weak digestion, insomnia associated with torpor, grief, fear or fatigue, and in people accustomed to such foods and drinks. The broader anupana principle is that a suitable after-drink helps food settle, supports digestion and assists assimilation.

3. Fermentation as a pharmaceutical method: In official Ayurvedic pharmaceutics, asava and arishta are not simply beverages. They are dosage forms in which herbal drugs, water or decoction, and fermentable sweet substances are combined and allowed to ferment. The generated alcohol assists extraction of herbal constituents and helps preserve the preparation.

4. Food transformation: In food science, fermentation is the microbial transformation of food components through controlled microbial growth and enzymatic activity. Cereal fermentation can change digestibility, taste, nutrient availability and B-vitamin profile. This supports the Ayurvedic observation that a fermented grain preparation has properties different from the same grain cooked plainly.

The Doshas and the Principle of Yukti

Charaka’s central rule is yukti: intelligent suitability. Properly used madya, with correct procedure, dose, time, food and personal capacity, is compared to nectar; improperly used, it is compared to poison. The same chapter asks the physician to consider age, disease, strength, season, food, dosha and mental constitution before allowing or administering such preparations.

Dominant Pattern	Classical Direction	Clinical Meaning
Vata	Unctuous, warm, grounding support; avoidance of dryness, fasting and overuse	Fermented preparations are considered only with nourishing food, warmth and careful dose when Vata depletion or obstruction is present.
Pitta	Cooling, sweet, unctuous and non-aggravating support	Because madya is generally hot, sharp and sour, Pitta-prone people require greater caution and should not use strong sour or heating preparations casually.
Kapha	Dry, hot, light and channel-clearing support	Kapha patterns call for lighter, drier and more stimulating measures, but the dose remains small and suitability remains essential.

Modern Ayurvedic Forms Still in Use

The living continuation of this tradition is seen most clearly in licensed Ayurvedic asava and arishta preparations rather than in recreational brewing. These are medicinal dosage forms, usually taken in small measured quantities with water, and should be selected according to constitution, disease, age, digestion and concurrent medicines.

Pārthādyariṣṭa / Arjunarishta: An official arishta formulation built around Arjuna bark, with Draksha, Madhuka, Dhataki and jaggery. It contains self-generated alcohol in the standard asava-arishta range.
Dashamularishta: An official fermented formulation based on the Dashamula group and related ingredients, containing self-generated alcohol within the standard range for this class of medicines.
Ashwagandhadyarishta: An official fermented formulation containing Ashwagandha root and other ingredients. Its listed uses include conditions such as emaciation, impaired digestion and Vata disorders, and the official dose is a small measured quantity with equal water after meals.
Drakshasava and other asavas: Asava preparations follow the same fermented-medicine principle, but are prepared without first making a decoction. Their use depends on the particular formula, not on the word “fermented” alone.

Dosage: Matra, Not a Pour

Classical Ayurveda does not support free home use of alcoholic ferments. The governing principle is matra, the correct dose for the correct person. In present Ayurvedic pharmacy practice, many official asava and arishta monographs specify small medicinal doses, commonly around 15–30 ml with an equal quantity of water after meals, but the exact dose belongs to the specific product and the prescribing practitioner.

Preparation Type	How It Should Be Understood	Practical Caution
Classical Sura or Madya	A potent fermented preparation discussed in relation to food, constitution, disease and intoxication	Not a home self-treatment or recreational substitute for medicine
Asava and Arishta	Medicinal fermented dosage forms with self-generated alcohol	Use only in measured dose, usually diluted, and only when suitable
Sour grain ferments such as Sauviraka-type preparations	Digestive sour fermented grain liquids in the classical food-and-drink tradition	Not interchangeable with alcoholic arishta medicines or with modern beer

Safety and Contraindications

Fermented alcoholic medicines are not appropriate for everyone. Classical Ayurveda repeatedly warns that the wrong dose, wrong person, wrong food or wrong time can turn madya from a useful substance into a cause of disease. Modern safety rules make this caution even more important.

Avoid alcohol-containing preparations during pregnancy or when trying to conceive, unless a qualified healthcare professional has explicitly advised otherwise; public health guidance states that no safe amount of alcohol is known during pregnancy.
People with alcohol use disorder, current or past alcohol dependence, liver disease, hepatitis, cirrhosis or strong personal risk from alcohol should avoid alcohol-containing asava and arishta preparations.
Do not combine alcohol-containing Ayurvedic medicines with metronidazole, tinidazole or disulfiram. People taking sedatives, opioids, psychiatric medicines, anticoagulants, methotrexate, diabetes medicines or other long-term prescriptions should consult a healthcare provider before use.
Children, frail elderly people and people with serious medical conditions should use these preparations only when directly supervised by a qualified practitioner.
Do not use these preparations before driving, operating machinery or performing work that requires alertness.

The most faithful modern reading of the classical material is not “Ayurveda recommends alcohol.” It is that Ayurveda understood fermented preparations as powerful, highly conditional substances. In the right formula, dose and patient, they may serve as digestive, nourishing or herbal vehicles; in the wrong setting, they can disturb ojas, senses, mind and health.

This article is educational and historical. Any therapeutic use of alcohol-containing asava or arishta preparations should be guided by a qualified Ayurvedic physician and, when relevant, a healthcare provider. Do not use these preparations if you are pregnant, have liver disease, have alcohol use disorder, or take medicines that interact with alcohol.

Fermented Grain Drinks in Ayurveda: Sura, Maireya, and the Therapeutic Use of Fermented Beverages

Rohan Kapoor — Fri, 05 Jun 2026 07:30:00 +0000

When I first encountered Ayurveda’s discussions of fermented beverages, the most striking feature was not a single recipe but the range of distinctions the texts make. The Charaka Samhita does enumerate eighty-four selected asava preparations, but it does not present them as eighty-four grain drinks arranged like a modern pharmaceutical catalogue. In Sutra Sthana 25, the number arises from source materials drawn from grains, fruits, roots, pith or heartwood, flowers, branches, leaves, bark, and sugar. Charaka also states that further combinations of ingredients and processing methods could produce innumerable variations.

The classical literature therefore treats fermentation as both food processing and medicine-making. It distinguishes cereal-derived intoxicating drinks, sour grain ferments, and self-fermented herbal formulations. It also treats alcohol as a substance whose effects change with its ingredients, preparation, age, quantity, timing, accompanying food, the drinker’s strength, and habituation. These are traditional Ayurvedic descriptions rather than modern clinical proof, but they demonstrate close attention to preparation, individual suitability, and the consequences of misuse.

Where the Classical Material Actually Appears

The principal Charaka passages are distributed across Sutra Sthana 25, which enumerates the selected asavas; Sutra Sthana 27, whose Madya Varga compares fermented and sour preparations; and Chikitsa Sthana 24, which discusses appropriate drinking, intoxication, susceptibility, and treatment of madatyaya. The Sushruta Samhita discusses liquid substances, including fermented beverages, in Sutra Sthana 45—not in Sharira Sthana.

Term	Verified Description	Important Correction
Asava	A broad self-fermented preparation. Charaka lists several possible source materials and says its effects depend on the ingredients and processing.	The eighty-four selected asavas are not all grain beverages or eighty-four fully standardized modern recipes.
Sura	A cereal-derived alcoholic preparation, commonly associated in later Ayurvedic pharmaceutic descriptions with cooked grain and a fermenting starter.	Charaka Chikitsa Sthana 24 does not give the claimed sesame-oil recipe or a universal three-to-seven-day fermentation schedule.
Prasanna	The clear upper or supernatant portion associated with sura in Ayurvedic pharmaceutic literature.	It is not simply rice-cooking water left overnight.
Arishta	A medicated fermented preparation. In later pharmaceutical usage, the principal herbs are generally first prepared as a decoction and fermented with a sweetening material.	Its therapeutic indication depends on the complete formula, not on fermentation alone.
Asava in later pharmacy	Generally prepared without first converting the principal herbal material into a decoction; the exact liquid, herbs, sweetening agent, and fermentation procedure vary by formula.	Defining every asava as fermented raw herbal juice is too narrow.
Kanjika or Dhanyamla	A sour fermented cereal liquid described separately from intoxicating grain beverages.	A modern carrot-and-mustard kanji recipe should not be presented as a verbatim classical formula without a textual source.

Sura and the Meaning of Madya

Madya is a broad term for intoxicating fermented drink, whereas sura is one cereal-derived member of that larger group. Charaka’s Madya Varga separately discusses sura, madira, jagala, arishta, maireya, dhātakyasava, sauviraka, tushodaka, and amla-kanjika. The text describes maireya as sweet and heavy, while dhātakyasava is listed separately and described as mild, dry, and appetizing. Maireya therefore cannot be defined simply as barley fermented with Dhataki flowers.

Charaka states that fresh liquor is generally heavy and liable to aggravate the doshas, whereas properly aged liquor is described as lighter, appetizing, digestive, and channel-clearing. In Chikitsa Sthana 24, madya is assigned ten qualities: laghu, ushna, tikshna, sukshma, amla, vyavayi, ashu, ruksha, vikashi, and vishada. The same chapter warns that alcohol used improperly or excessively can act like poison.

The text also recognizes differences in susceptibility. It describes hungry, thirsty, weak, emaciated, exhausted, angry, frightened, and unaccustomed individuals, as well as those taking little or dry food, as liable to become intoxicated rapidly. Classical Ayurveda consequently does not treat fermented alcohol as a universally strengthening or digestion-promoting substance. Quantity, context, constitution, strength, food, and habituation remain essential considerations.

Asava, Arishta, and the Role of Dhataki

In later Ayurvedic pharmacy, asava and arishta are self-fermented herbal dosage forms. A fermentable carbohydrate source such as jaggery, sugar, or honey supports microbial activity and generates ethanol within the preparation. The self-generated ethanol can assist the extraction of both water-soluble and alcohol-soluble constituents and contributes to preservation. The ingredients, proportions, vessel, duration, and quality-control requirements must nevertheless be taken from the authoritative formula for the individual medicine; a single thirty-day fermentation rule cannot be applied to every asava or arishta.

Dhataki flowers, obtained from Woodfordia fruticosa, occur in many but not all asava-arishta formulations. Laboratory investigations have isolated alcohol-producing yeasts and other microorganisms from the flowers and indicate that this associated microbial community can assist fermentation. It is therefore reasonable to describe Dhataki as a traditional fermentation aid where a formula includes it. It is not accurate to describe the flowers merely as a packet of “fermentation enzymes,” nor does the detection of compounds such as ellagic acid prove a particular clinical benefit in every finished medicine.

Each named asava or arishta remains a distinct formulation with its own ingredients, processing instructions, dose, and traditional indications. Fermentation alone does not make different products interchangeable. Manufacturing quality also matters. An analytical investigation of marketed Kumaryasava and Mustakarishta samples reported variation in measured ethanol values and emphasized the need for appropriate standardization and quality control.

What Modern Fermentation Science Can—and Cannot—Confirm

Fermentation may involve lactic-acid bacteria, yeasts, or mixed microbial communities, depending on the substrate, starter, temperature, time, hygiene, and other processing conditions. It can change acidity, flavour, preservation, nutrient availability, and plant chemistry. However, the word “fermented” does not automatically mean “probiotic.” Scientific consensus reserves the term probiotic for identified live microorganisms that have been shown, in adequate amounts, to confer a health benefit.

Microbial identity matters: Sour taste, bubbles, or a traditional name cannot establish which species or strains are present, whether they remain alive, or whether they are safe.
Health effects are product-specific: Findings from one controlled ferment cannot automatically be transferred to sura, kanjika, rice water, or a medicated asava-arishta.
Nutritional claims require analysis: Fermentation may alter vitamins, starches, amino acids, and other compounds, but it does not guarantee clinically important quantities or effects.

No verifiable 2018 systematic review was located that matched the original claim that traditional Asian grain beverages broadly demonstrated anti-inflammatory, immune-modulatory, and gut-protective effects in humans. Reviews of fermented foods support their microbial diversity and research potential, but evidence for clinical outcomes remains dependent on the particular food, organisms, process, dose, and population studied. Classical terms such as dipana and vata-shamana should not be translated directly into unproven claims about microbiome diversity, intestinal permeability, or probiotic efficacy.

Kanjika Is Not the Same as Every Modern Kanji Recipe

The carrot, mustard, salt, grain, and water recipe supplied in the original article was not verified as a formula from the Ashtanga Hridaya. Classical amla-kanjika, dhanyamla, sauviraka, and tushodaka belong to a vocabulary of sour cereal preparations and are discussed separately. Charaka describes amla-kanjika as sour and attributes appetizing, digestive, and laxative actions to it, while sauviraka and tushodaka receive their own descriptions. A household vegetable ferment may be a legitimate culinary tradition without being relabelled as an exact classical prescription.

Why Overnight Fermented Rice Water Was Removed

The proposed “Prasanna” method—leaving cooked rice water at room temperature for twelve to twenty-four hours and drinking it—was not supported by the cited classical material and introduces a food-safety concern. Cooked rice can contain surviving spores of Bacillus cereus. The longer cooked rice or its starchy water remains at room temperature, the greater the opportunity for bacterial multiplication and toxin formation. Sourness, effervescence, smell, or appearance cannot verify that an uncontrolled household ferment is microbiologically safe.

The claimed 2020 study reporting improved intestinal-flora diversity and reduced intestinal-permeability markers in adults with irritable bowel syndrome after fermented rice water could not be verified in the named journal and has been removed. Without an identifiable paper, authors, DOI, or trial record, it should not be used to support a therapeutic recommendation.

For information about Triphala, see our Triphala complete guide; Triphala should not be assumed to be a necessary companion to fermented preparations unless a qualified practitioner recommends it.

Fermented Ayurvedic medicines may contain self-generated alcohol and should be taken only in the labelled dose under the guidance of a qualified Ayurvedic physician or other appropriate healthcare professional. Avoid alcohol-containing preparations during pregnancy, with alcohol-related liver disease, before driving, or together with medicines that may interact with alcohol unless a clinician has specifically approved their use. Purchase licensed products, inspect the full ingredient and dosage information, and do not replace prescribed treatment with an uncontrolled home ferment.

Actionable tip: Instead of preparing overnight rice-water “Prasanna,” first identify the exact substance being considered. Is it an ordinary food ferment, a historical madya, or a licensed asava-arishta medicine? For a medicinal product, review the complete label, ingredients, dose, alcohol declaration where provided, contraindications, and current medicines with a qualified practitioner. This follows the classical emphasis on substance, processing, quantity, timing, strength, food, and individual suitability without converting an unverified household experiment into therapy.
