Kefir, a fermented drink with origins dating back over 4,000 years, has long been valued for its probiotic richness and digestive benefits. Traditionally made by fermenting cow’s milk with kefir grains (a symbiotic culture of bacteria and yeast) this ancient beverage has recently surged in popularity in wellness circles, often hailed as a natural way to support gut health.
But as kefir becomes more mainstream, it’s important to consider the ethical implications of how it’s commonly produced. Dairy-based kefir is tied to an industry that relies on systemic animal oppression: forced impregnation of cows, the separation of calves from their mothers, and the commodification of sentient beings for their milk—all practices that are unnatural and inherently exploitative.
Fortunately, kefir doesn’t have to come at such a cost. Vegan kefir, made from plant-based milks like coconut, oat, soy—or even water kefir—offers a healthier alternative. It delivers similar probiotic benefits without the ethical concerns associated with dairy production. As awareness grows, so too does the availability of these plant-based options, making it easier than ever to prioritize both personal wellness and your vegan values.
What Is Kefir?
Kefir is a tart, slightly effervescent drink that is often compared to yogurt but is thinner in texture. Unlike yogurt, however, which typically contains around six strains of beneficial bacteria, kefir can contain up to 20 or more strains of probiotics, including both bacteria and yeasts, making it one of the most diverse and potent fermented foods for gut health.
During fermentation, the kefir grains consume sugars and produce lactic acid, beneficial enzymes, carbon dioxide, and trace amounts of alcohol. The result is a drink that supports gut health by promoting a balanced microbiome, which is a key factor in digestion, immune function, skin health, and even mental clarity.
Traditional kefir is of course made with dairy, but dairy is not essential to the fermentation process. The real key lies in the action of live cultures, which can thrive just as effectively in non-dairy mediums. This opens the door to more ethical and inclusive ways of enjoying kefir, without the use of animal milk.
Why Choose Plant-Based Kefir?
For those exploring alternatives to dairy, the reasons are often deeply rooted in a broader view of wellness; one that includes not just personal health, but also respect for our fellow animals and the ecosystems that support us all.
Plant-based kefir removes from the equation the ethical issues around animal agriculture, which cannot be avoided even when choosing dairy from small-scale operations. In addition to the impact on the animals it exploits, dairy is a resource-intensive industry which contributes to deforestation, water depletion, methane emissions, and waste runoff. By contrast, plant-based kefir is significantly less ecologically damaging.
From a health standpoint, many people experience digestive issues related to lactose or casein, both found in milk. Plant-based kefir eliminates these allergens while still offering probiotic support. And with a wide range of bases, from coconut milk to oat and even simple sugar water, vegan kefir can suit many different nutritional needs and taste preferences.
Types of Vegan Kefir
Vegan kefir can be made at home or purchased from one of a growing number of brands offering a variety of vegan options based on either water or plant milk. Many companies offer fortified options with added B12, calcium, and vitamin D.
Plant Milk Kefir
Plant-based kefir can be made using non-dairy milks like coconut, soy, oat, cashew, or hemp. (Coconut milk, in particular, creates a rich and satisfying texture, and is a favorite for the store-bought varieties.) These milks are fermented using either commercially available dairy-free starter cultures (see below for sources) or adapted kefir grains. (While traditional kefir grains are accustomed to lactose, many home fermenters such as this one report success transitioning their grains to plant-based milks over time.)
The final product is creamy, tangy, and full of beneficial bacteria, without the need for any animal milk.
Water Kefir
Water kefir is made by fermenting a sugar-water solution or coconut water with water kefir grains. These grains differ slightly from milk kefir grains, but function similarly. After fermentation, the resulting beverage is mildly sweet, slightly fizzy, and easily flavored with fruit, herbs, or citrus.
Water kefir is especially appealing because it is free from all major allergens—dairy, soy, gluten, and nuts—making it an inclusive probiotic option.
Making Vegan Kefir at Home
Creating vegan kefir at home is simple and requires minimal equipment. You can use a cheesecloth, muslin, tea towel, coffee filter, nut bag or even a folded paper towel to create a breathable entryway over your glass container. Be sure to use a clean glass jar, and non-metal utensils, as reactive metals can interfere with the fermentation process.
Kefir Grains (and how to source them)
For those new to vegan kefir, understanding the different types of kefir grains and how to source them is essential. Kefir grains are live cultures of bacteria and yeast used to ferment liquids, but not all grains work the same way.
Milk kefir grains are traditionally used with dairy but if they are your only choice, they can often be adapted to ferment plant-based milks like soy, oat, or coconut. However, this adaptation takes time, and the grains need proper care to stay healthy. True vegan milk kefir grains (that have never been exposed to dairy) are not unheard of, but they are rare.
Water kefir grains (also called tibicos) naturally ferment sugar water, coconut water, or juice. They are fully vegan and create a bubbly, fruity drink. Note that these grains do not ferment plant milks and they require sugar water or juice to thrive.
Much like a kombucha scoby, both milk and water kefir grains will multiply over time as you feed them, so a single purchase will last forever, as long as you don’t neglect them.
Powdered kefir starters, on the other hand, don’t require ongoing grain maintenance but are typically for single or limited use. These freeze-dried cultures are ideal for beginners, as they provide an easy, vegan-friendly alternative for creating either water or plant-milk kefir.
You can source vegan kefir grains and starters from trusted online shops like Cultures for Health or Kefirko, or sometimes from local health food stores, or fermentation groups. Always verify that the grains or starters are suited for plant-based fermentation and have not been grown on dairy.
Instructions:
For plant milk kefir, combine 2 cups of your chosen milk with a starter culture in a clean glass jar. Let it sit at room temperature in a cool, shaded area out of direct sunlight for 24–48 hours (the time depends on your preference for consistency, since kefir thickens as it sits.) Then refrigerate after fermentation. The flavor will continue to develop slightly in the fridge.
Keep in mind that not all plant milks perform equally in kefir-making. Many store-bought milks are low in natural sugars, which the cultures need to ferment properly. In these cases, it’s often necessary to add 1–2 teaspoons of sugar (such as organic cane sugar, maple syrup, or coconut sugar) to the milk before fermentation, in order to feed the microbes.
After fermenting milk kefir, the grains are strained out and reused for the next batch. Unlike water kefir grains, milk kefir grains generally should not be rinsed, as washing them, especially with chlorinated water, can damage their delicate microbial balance. Once strained, the grains can be placed directly into fresh milk to begin a new fermentation cycle. If you’re not making another batch right away, the grains can be stored in the refrigerator in a small amount of fresh milk, which should be changed every 5 to 7 days to keep them healthy. (For longer breaks, the grains can be frozen or dehydrated, though this may weaken them.)
A second fermentation, done after removing the grains, involves letting the strained kefir sit at room temperature for another 6 to 24 hours. This process enhances its natural flavor, and allows for optional additions like fruit or spices.
For water kefir, dissolve 1/4 cup of organic cane sugar in 4 cups of water, add water kefir grains, and ferment for 24–48 hours for the first fermentation at room temperature.
The second fermentation is when you take the strained kefir (after removing the grains) and let it sit a second time. The grains are strained out and reused but unlike milk kefir, water kefir grains can be gently rinsed if needed, especially if they’ve been in flavored or sugary mixtures, though it’s not always necessary.
After straining, you can start a new batch immediately by dissolving fresh sugar in water and adding the grains again. If you’re taking a break, the grains can be stored in the refrigerator in sugar water (not plain water), which should be refreshed every 1–2 weeks to keep them alive. (For long-term storage, water kefir grains can be dehydrated or frozen, though this may impact their strength.)
Like milk kefir, water kefir can go through a second fermentation. After removing the grains, the liquid is bottled (often with fruit or spices) and left at room temperature for another 24–48 hours. This enhances flavor, increases carbonation, and allows for creative infusions. This is done usually with added flavorings, to develop more complex flavors, slightly increase carbonation (natural fizz) and reduce sugar further (as microbes keep feeding.) You can enhance the second fermentation with slices of ginger, berries, or citrus peel for natural flavoring.

Ethical and Holistic Considerations
Choosing vegan kefir isn’t just a dietary decision. It reflects a broader value system rooted in non-harm, sustainability, and respect for all life. Every bottle or jar of plant-based kefir is a small step away from industries that rely on the commodification of our fellow animals and the depletion of natural resources. With rising accessibility, there’s little need to choose between ethics and wellness as they can, and increasingly do, go hand in hand.
Plant-based kefir supports a food system that is more regenerative, just, and inclusive. It empowers people to care for their own bodies while aligning with values that consider the rights of other sentient beings and future generations.
Kefir is no longer synonymous with dairy. Through water kefir and plant milk kefir, people can enjoy the ancient benefits of fermentation without the ethical and environmental costs tied to animal agriculture. Whether made at home or purchased ready-to-drink, vegan kefir is a vibrant, living beverage that supports gut health, aligns with vegan values, and offers a nourishing path toward conscious consumption.
