Shubat: Kazakhstan’s Fermented Camel Milk With a Nutritional Profile Unlike Any Other Dairy

There is a particular kind of cultural hierarchy in the fermented dairy world, and camel milk sits near the top of it — not because it is the best-known, but because it is the least understood outside the regions where it has been consumed for millennia. I first encountered shubat at a small Kazakh cultural festival in Germany, where it was served chilled in ceramic bowls alongside kurt (dried sour cheese balls). The taste was startling: tangier than kefir, slightly carbonated, with a faint sweetness and a thin texture that felt lighter than its protein content suggested. I asked the woman serving it what the secret was. She looked at me like the question answered itself. The secret, she said, is the camel.

She was right. Camel milk is not cow milk with different branding. It is a fundamentally different fluid, shaped by millions of years of adaptation to environments where water is scarce, food is sparse, and the animals producing it need to concentrate nutrients for offspring under the harshest possible conditions. Understanding shubat means understanding why camel milk is unlike anything else in the fermented dairy world.

Camel Milk: The Biochemistry of an Arid-Adapted Food

Camel milk composition varies by species, season, diet, and hydration status — but certain differences from cow milk are consistent. Fat globule size in camel milk averages 1.4–4.5 μm compared to 2–6 μm in cow milk. This smaller, more uniform size means camel milk fat is more rapidly digested and absorbed, and the milk does not separate easily into cream and skim fractions without centrifugation. This is one reason why camel milk cannot be made into butter by traditional churning methods — the fat simply won’t coalesce under mechanical agitation alone.

Protein structure is more consequential. Camel milk lacks β-lactoglobulin entirely — the whey protein responsible for the majority of cow milk allergies and intolerance reactions. Its caseins are present but structurally different from bovine caseins, forming smaller, more fragile micelles that digest more easily and coagulate differently under acidification. This is why shubat has a thinner consistency than kefir made from cow milk even at comparable protein concentrations: the gel structure is less robust.

Vitamin C content in camel milk is approximately 3–4 times higher than in cow milk — around 15mg per 100ml versus 1–2mg in cow milk. In the Kazakh steppe, where fruits and vegetables were historically unavailable during winter months, camel milk served as the primary dietary source of vitamin C for nomadic populations. Scurvy was largely absent in camel-herding communities despite diets that would have produced it in populations dependent on cow or horse milk alone.

The insulin-like proteins in camel milk have attracted the most biomedical interest. Several studies (El-Hatmi et al., 2007; Abdel-Salam et al., 2013; Al-Ayadhi & Elamin, 2012) have identified small proteins in camel whey that resist gastric acid and reach the intestine intact, where they may exert insulin-like activity. The mechanism remains contested and clinical evidence is mixed, but the traditional use of camel milk in managing symptoms associated with diabetes-like conditions across multiple cultures — Kazakhstan, parts of Africa, the Arabian Peninsula — has prompted ongoing pharmaceutical interest.

Shubat vs Kumiss: Two Fermented Milks, Two Cultures

Both shubat and kumiss are Central Asian fermented dairy drinks with ancient histories, but they are distinct products from distinct animals. Kumiss (qymyz) is fermented mare’s milk — typically more acidic, with higher alcohol content (1–3% ABV), thinner consistency, and a sharper flavor. Shubat is fermented camel milk — milder in acidity when fresh, slightly thicker, with lower alcohol content in typical preparations, and a faint characteristic sweetness.

Culturally they also occupied different roles in Kazakh society. Kumiss was associated specifically with spring and summer — the season when mares were in milk — and with celebrations. Shubat, from camels that produced milk more continuously across the year, was more of a year-round staple. In some historical accounts, shubat was considered specifically medicinal, prescribed for tuberculosis patients, those recovering from surgery, and the elderly. Soviet-era shubat sanatoria in Kazakhstan treated tuberculosis patients with daily doses, a practice that continued into the 1980s, though the mechanism — whether bacterial, nutritional, or immunological — was never conclusively established.

The Microbiology of Shubat Fermentation

Shubat is made by spontaneous fermentation of fresh camel milk, sometimes seeded with a small portion of previous-batch shubat (back-slopping). The microbial consortium is diverse. Studies by Serikbayeva et al. (2020, Food Chemistry) and Yimit et al. (2012, Journal of Dairy Research) have identified the following dominant organisms:

Lactic acid bacteria: Lactobacillus casei, L. acidophilus, L. fermentum, Pediococcus acidilactici, Leuconostoc mesenteroides, and Enterococcus faecium. These produce the lactic acid that acidifies and preserves the product.

Yeasts: Kluyveromyces marxianus (the dominant yeast species, known for lactose fermentation and ethanol production), Torulaspora delbrueckii, and Candida spp. The yeast activity produces the characteristic light carbonation and mild alcohol content.

The LAB and yeast populations work synergistically: yeast produces CO₂ and trace ethanol, LAB produces lactic acid and antimicrobial bacteriocins that help prevent pathogen growth. The result is a product preserved by both acid and mild alcohol — safe in ambient conditions for 24–48 hours, longer when chilled.

The protein in shubat is hydrolyzed by microbial proteases during fermentation, releasing bioactive peptides. Serikbayeva et al. (2020) identified ACE-inhibitory and antioxidant peptides in traditionally fermented shubat at significantly higher concentrations than in raw camel milk — the fermentation step increases, not just transforms, the bioactive content.

Making Shubat at Home

Fresh camel milk is unavailable in most parts of the world. Where it can be obtained (specialty Middle Eastern grocers in some cities now stock it; a small number of North American and European camel dairies ship fresh or frozen), genuine shubat is straightforward to make. Where camel milk is unavailable, a reasonable approximation using goat milk — the closest bovine milk to camel milk in fat globule size and allergenic protein profile — is possible, though the flavor will differ.

With Camel Milk (Traditional Method)

• 1 litre fresh raw camel milk (or pasteurized, though raw ferments more reliably)
• 2–3 tablespoons previous-batch shubat or good-quality kefir as starter (optional — raw milk will self-ferment, but starter accelerates and directs the process)

1. Pour milk into a clean clay pot or glass jar. If using a starter, stir it in thoroughly.
2. Cover loosely (cheesecloth or a loose lid — the fermentation produces CO₂ that needs to escape).
3. Ferment at 25–30°C for 6–12 hours. Taste at 6 hours: shubat should be pleasantly sour, slightly effervescent, and thin to medium-bodied. For more acidity, continue to 12 hours.
4. Chill before serving. Traditionally served very cold. Keeps 2–3 days refrigerated.

Approximate Version With Goat Milk

• 1 litre full-fat goat milk
• 3 tablespoons kefir with active grains, or water kefir grains, as starter

1. Warm goat milk to 30°C. Stir in kefir starter.
2. Ferment at 25–28°C for 8–16 hours until pleasantly sour and slightly carbonated.
3. The result will be tangier and thinner than cow-milk kefir, approaching the texture and acidity profile of shubat.

Nutritional Comparison: Shubat vs Kefir vs Kumiss

Per 100ml (approximate, fermented product):

• Shubat: 50–60 kcal, 3g fat, 3.5g protein, 3.5g carbohydrate, 15mg vitamin C, 0.5–2% ABV. No β-lactoglobulin.
• Cow milk kefir: 60–70 kcal, 3.5g fat, 3.5g protein, 4.5g carbohydrate, 1mg vitamin C, 0.5–1% ABV.
• Kumiss (mare’s milk): 45–55 kcal, 2g fat, 2g protein, 4g carbohydrate, 5mg vitamin C, 1–3% ABV.

Shubat’s standout figures are the vitamin C (10× cow milk kefir) and the absence of the dominant cow milk allergen. For people who react to cow dairy but have not tried camel milk, shubat is worth investigating — though individual responses vary and camel milk is not universally tolerated either.

Frequently Asked Questions

Is shubat alcoholic?

It contains 0.5–2% ABV in typical preparations — comparable to a very weak beer or a glass of kombucha at the high end. Traditional shubat is considered a non-intoxicating beverage in Kazakh culture and is consumed by all ages including children. Extended fermentation at warm temperatures can push alcohol content higher (up to 4%), producing a more intoxicating product that is considered distinct from everyday shubat.

Where can I buy camel milk?

In the United States: Desert Farms (dessertfarms.com) ships fresh camel milk nationally; some Middle Eastern and Somali grocery stores stock it. In the UK: a handful of UK camel dairies now sell direct. In Europe: Camelicious (UAE brand) is available in some specialty stores. Online availability has improved significantly since 2020 as interest in camel milk has grown.

Is camel milk safe for people with lactose intolerance?

Camel milk contains lactose (3.4–5.8%), somewhat lower than cow milk (4.7%), but not negligible. However, the combination of smaller fat globules, different protein structure, and lower lactose means many people who cannot tolerate cow milk report tolerating small amounts of camel milk. Shubat, being fermented, has lower lactose still — LAB convert a portion during fermentation. Individual tolerance varies; start with small amounts.

Can shubat be made from pasteurized camel milk?

Yes, with a starter culture. Pasteurization eliminates the natural microbial flora, so raw-milk spontaneous fermentation is no longer possible, but inoculating with kefir grains or a previous-batch shubat starter works reliably. Flavor may be slightly less complex than raw-milk shubat but the product is safe and nutritionally equivalent.

How is shubat different from the camel milk products sold in health food stores?

Most camel milk sold in health food stores is pasteurized, non-fermented liquid or freeze-dried powder. It retains the nutritional profile but lacks the live cultures, bioactive peptides produced by fermentation, and characteristic flavor of shubat. The fermentation step is not just preservation — it transforms the nutritional and sensory profile in meaningful ways.

How long does shubat keep?

At room temperature (25°C), 12–24 hours before it becomes too sour. Refrigerated, 2–3 days. Unlike kefir, which stabilizes at a certain acidity, shubat continues fermenting relatively quickly even when chilled. Traditional nomadic consumption was immediate — made fresh each day from that morning’s milking. Home production should follow similar timing.

The Camel’s Particular Intelligence

There is something worth sitting with in the nutritional profile of camel milk. An animal adapted over millions of years to the harshest possible environment — minimal water, extreme temperatures, sparse food — produces milk that is higher in vitamin C than almost any other mammalian milk, lower in the proteins most likely to cause allergic reactions, and containing proteins that reach the human bloodstream intact rather than being digested en route. This is not accidental. These are evolutionary adaptations that made survival possible for populations who had no other reliable source of these nutrients.

Shubat is what happens when you take that already-extraordinary milk and add a consortium of lactic acid bacteria and yeasts that have co-evolved with the same pastoral communities for thousands of years. The result is a drink that fed nomadic empires, treated tuberculosis patients, and is now attracting biomedical research interest from institutions in Switzerland, the UAE, China, and the United States simultaneously. The camel knew what it was doing. We are still catching up.
