Can Yogurt Be Made Without Milk? Yes, It's Easier Than You Think

While traditional yogurt is made from dairy milk, a growing market of delicious and probiotic-rich vegan alternatives has emerged. This demonstrates that you can indeed make yogurt without milk, using plant-based options like coconut, soy, almond, and cashew instead.

Quick Summary

Dairy-free yogurt can be made by fermenting plant-based milks with a probiotic starter and often requires a thickener to achieve a creamy texture. Common bases include coconut, soy, almond, and cashew milk, each offering unique flavors and nutritional profiles. Homemade vegan yogurt is a customizable alternative to store-bought varieties.

Key Points

• Yes, you can make yogurt without milk: Instead of dairy, fermentation can be performed on plant-based milks like coconut, soy, and almond milk.

• Plant-based yogurt requires a starter culture: Like dairy yogurt, non-dairy versions rely on live active cultures, often sourced from probiotic capsules or specialty packets.

• Thickeners are often necessary: Because plant milks lack dairy's protein structure, thickeners like agar agar or tapioca starch are commonly used to achieve a firm texture.

• Choice of milk affects final product: Different plant milks yield varying flavors and consistencies; soy milk makes a thick, high-protein yogurt, while almond milk is lighter.

• Homemade yogurt offers control: Making your own allows you to control ingredients, fermentation time, and flavor profile, avoiding unwanted additives.

• Proper temperature is crucial: Maintaining a consistent warm temperature during incubation is key for successful fermentation and yogurt setting.

The Essentials of Non-Dairy Yogurt Making

Creating yogurt without milk relies on the same basic principle as traditional yogurt: fermentation. However, because plant-based milks lack the same protein structure as dairy milk, the process requires some key adjustments to achieve a desirable texture and tang. The core components include a milk alternative, a starter culture with live active cultures, and often a thickener to achieve a spoonable consistency. Sterilizing your equipment is a crucial first step to ensure only the beneficial bacteria thrive.

Selecting Your Plant-Based Milk

The choice of plant milk is the most important factor and will influence the final flavor, texture, and nutritional content of your yogurt.

Common options include:

• Coconut Milk: Yields a rich, creamy yogurt with a distinctly tropical flavor, often requiring minimal added thickener if using full-fat canned varieties.
• Soy Milk: A good choice for a thick and protein-rich yogurt. It naturally sets well and provides all essential amino acids. Unsweetened, additive-free soy milk is recommended for best results.
• Almond Milk: Produces a lighter, more pourable yogurt with a nutty flavor. It requires added thickeners to achieve a spoonable texture and extra sugar to aid fermentation.
• Cashew Milk: Creates a very rich and creamy yogurt, similar to coconut milk. It is low in protein but high in healthy fats.
• Oat Milk: Offers a higher carbohydrate and calorie count with a good amount of fiber. It generally requires a thickener.

The Fermentation Process and Starter Cultures

Once you have your milk alternative, the fermentation begins with the addition of a starter culture. For homemade vegan yogurt, you can use one of several options:

• Probiotic Capsules: Simply open the capsules and sprinkle the powder over the cooled, heated plant milk. This is a popular and straightforward method.
• Vegan Yogurt Starter Packets: Specialty cultures are available commercially, formulated with specific vegan-friendly bacteria strains like Lactobacillus bulgaricus and Streptococcus thermophilus.
• Store-Bought Vegan Yogurt: A few tablespoons of a pre-made, unflavored, vegan yogurt with live active cultures can be used to inoculate a new batch.

Necessary Thickeners for Dairy-Free Yogurt

Unlike dairy milk, most plant-based milks need a little extra help to become thick and creamy. Common thickeners include:

• Agar Agar: A gelatinous substance derived from seaweed. It's a vegan alternative to gelatin and creates a firm, set texture.
• Tapioca Starch: Helps achieve a smooth, slightly gooey consistency.
• Pectin: Can be used to create a very firm Greek-style yogurt.

Step-by-Step Method for Homemade Vegan Yogurt

1. Sterilize your equipment. Begin by washing jars, thermometers, and utensils thoroughly with hot, soapy water, or run them through a dishwasher.
2. Heat the milk. Gently heat your chosen plant-based milk to 180°F (82°C) while stirring. If using a thickener like tapioca starch, create a slurry with a small amount of cold milk first to prevent clumping. Maintain this heat for several minutes to dissolve thickeners and kill unwanted bacteria.
3. Cool the milk. Remove the saucepan from the heat and allow it to cool to a temperature between 110°F to 115°F (43-46°C). This is the ideal temperature for the probiotic cultures to thrive.
4. Add the probiotics. Gently whisk in the contents of your probiotic capsules, a vegan yogurt starter packet, or a few spoonfuls of a previous batch of vegan yogurt.
5. Add sugar (optional). A small amount of sugar (around 1-2 teaspoons per cup of milk) can help feed the bacteria and improve fermentation, though the final yogurt will not be overly sweet as the sugar is consumed. Soy milk and rice milk have enough natural sugars and often don't need additional sugar.
6. Incubate. Pour the mixture into sterilized jars. Place the jars in a warm, consistent temperature environment (around 110°F), using a yogurt maker, an Instant Pot with a yogurt function, or an oven with just the pilot light on. Ferment for 8-12 hours, or longer for a tangier flavor.
7. Chill and set. After fermentation, refrigerate the yogurt for at least 4-6 hours. It will thicken considerably as it chills.
8. Strain for a thicker consistency. For a Greek-style texture, line a strainer with cheesecloth and let the yogurt drain for several hours to remove excess liquid.

The Health Benefits of Plant-Based Fermentation

The fermentation of plant milks with live cultures provides a host of benefits, including a healthy gut microbiome. These probiotics can aid digestion, bolster the immune system, and help with the absorption of essential nutrients like vitamins C and B12. Many plant-based yogurts are also cholesterol-free and lower in saturated fat than their dairy counterparts. This makes them a smart choice for maintaining both digestive health and cardiovascular wellness.

Common Flavorings and Uses

Once your non-dairy yogurt is chilled and set, you can customize it with a variety of flavorings and use it in countless ways. Add maple syrup, vanilla extract, or fresh fruit for a sweet taste. For savory applications, use plain, unflavored yogurt as a base for dressings, dips, or to add creaminess to soups.

Troubleshooting Your Homemade Yogurt

• Too runny? Ensure your incubation temperature was consistent and high enough. Try adding more thickener or straining the finished yogurt through cheesecloth for a thicker texture.
• Not tangy enough? Extend the incubation time. Longer fermentation leads to a more pronounced tangy flavor.
• Separation? This is common with plant milks. Simply whisk the yogurt after chilling to recombine the liquids and solids for a smooth consistency.
• Mold? If you see any signs of discoloration, dispose of the batch immediately. This indicates contamination, likely from equipment that wasn't properly sterilized. Start over with fresh ingredients and thoroughly clean all tools.
