How to Make Unsweetened Dairy Free Yogurt Using Soy, Almond, Or Other Alternative Milk
I will Make It Myself Then!
Are you on a special diet or live with specific dietary restrictions? If so, you know where I'm coming from. I suffer from digestive issues, plus I am allergic to dairy products. My health problems factor in to why I became a vegan.
My doctor suggested that I start eating plain unsweetened yogurt to aid my digestion. Easier said than done. Unsweetened plain non-dairy yogurt is as elusive as spotting a yeti. So, you can imagine my frustration when the yogurt I was buying was taken off the market. Not only that, but after hours of research on the web, I couldn't find another brand to replace it.
What do you do when you need a special food for your health reasons and you can't find it? You throw a tantrum. You lament that the universe is against you. You sulk. Well, at least, that's what I do. Then, you decide to make it yourself.
As I read articles on to make dairy free yogurt, I was beset with doubts. Many people tried. Some succeeded but only after many bad batches. Some found it too difficult and gave up. Was it worth even trying?
I wasn't going to let this soy yogurt beat me. No sirree! I will do it and do it well or waste a heck of a lot of soy milk trying.
Let's go make some vegan yogurt!
What Do You Need?
This is all you need to make yogurt. No fancy machine required!
- a pot to warm the soy milk
- a spoon for stirring the soy milk and cultures
- a measuring cup unless you buy quart sized soy milk containers
- a mason jar with a lid (or any 1 quart sized glass jar)
- a candy thermometer to make sure the soy milk is at the correct temperature when adding the cultures
- an oven temperature gauge to make sure the oven is at the right temperature for incubation
- a towel to cover the mason jar to keep it warm in the oven
The only other item you need is an incubator. If you have an oven, you can make yogurt.
What Goes into Making Homemade Yogurt?
Once I did my research, I was surprised at how little you need to make yogurt at home. The ingredients are simple: soy (or alternative) milk and yogurt cultures. That's it! Oh, you can add fruit, flavorings, and sweeteners, but since I want plain unsweetened, I would only need two ingredients.
It is possible that the yogurt can come out too thing or runny. A thickener like agar agar or flax seed powder might be necessary. I decided against using anything. I wanted to see how it would turn out without any additives.
Two ingredients...that seems like something I could handle. I used Silk Unsweetened plain soy milk, which is what I always buy. You can use whatever soy milk you like. I have heard that people have great results with soy and almond milk, but rice milk doesn't work as well.
Finding vegan cultures (there is a difference) was a bit more difficult. I didn't want to spend $30 on a jar that I may only use once. Several people recommended Cultures for Health Vegan Yogurt Start, so I went with that. It was fairly cheap and others had tested it.
With my two ingredients in hand, it was time to start making yogurt.
A note about yogurt cultures There are two types of yogurt cultures: Direct Set and Reculturable. As the name implies, Reculturable cultures can be used repeatedly. You take some of your last batch of yogurt and use it to culture the next batch.
The type I used are called Direct Set cultures. Direct Set cultures can only be used once. You cannot make another batch using a portion of the yogurt in your current batch.
The equipment needed is simple
Unless you're a really good judge of temperatures, you'll need a thermometer. I started out with a candy thermometer. It worked really well and was accurate. Then, after about 6 months of use, I was washing it in the sink and a big chunk of glass broke off. Arthritic hands and glass don't go together. After getting advice from a friend, I bought a simple meat thermometer. It's light weight and easy to use. It's your choice though. Either will do the trick!
A word to the wise on selecting a thermometer. Make sure it is watertight. My second candy thermometer had a plastic cap on top. It was not water tight and filled with water after the first wash. Stick to thermometers that won't let in liquid.
Soy milk temperature
The soy milk must be 110F when you add the yogurt cultures. Too hot or too cold and they aren't able to do their thing.
Colleen TowlerTells Us How To Do It
I would not have made yogurt had it not been for Colleen Towler and the information on her Waking Up Vegan website. This video walks you through how Colleen makes yogurt. Be sure to check out her website for more information. She offers several handy tips for fruit flavored and thicker yogurt.
Let's Make Yogurt!
- 4 cups Unsweetened Plain Soymilk
- 1 Packet Vegan Yogurt Cultures, from Cultures for Health (or equivalent)
- Wash your pot, jar, lid, thermometer, measuring cup, and fork or whisk. Set them out to dry on a towel on the counter. Once everything is dry you are ready to start.
- Empty the oven. Put your oven temperature gauge on a shelf where you can see it. Turn the oven light on and close the door. It should take about an hour to reach 108F.
- Heat 4 cups (1 quart) of soy milk to 110F. Use the lowest setting on your stove burner. It takes about 4 minutes to warm the milk to 110F on the lowest setting. The Cultures for Health Vegan cultures do not need to be brought to a boil like some other cultures. Don't worry if you test the milk and it's too hot. You can cool it down the right temperature. Just turn off the burner and let the pot sit. Check the temperature with your candy thermometer after about 10 minutes. When it's down to 110F, you're ready to go!
- About 3 minutes before the yogurt is at the right temperature, bring out your yogurt cultures if you've kept them in the freezer or fridge. This is so they'll be about the same temperature as the milk. I was told this was important for the cultures to thrive.
- Pour the yogurt cultures into the pot with the soy milk. Stir the mix until the cultures are 2-3 minutes which will allow the cultures to become fully dissolved and evenly distributed. A whisk is recommended. I don't have a whisk, so I use a fork.
- 5. Pour the soy milk into a glass jar. Wipe up any excess you've spilled around the jar with a clean paper towel or dish towel. You don't want to mix any bacteria from dirty towels into your mixture. Don't put on the lid!
- Make sure the oven gauge reads 108F before placing your yogurt in the oven. Place the jar on the shelf. Cover it with a dish towel, keeping the towel over the top, and wrapped around the sides so it is mostly covered. (It is not necessary to cover the bottom.) Close the door and walk away for at least 7 hours. It will need at least that long to set.
Do You Need to Sterilize The Equipment?
I noticed that people were in complete disagreement over the necessity of sterilization. Some didn't bother. Others were adamant that without sterilization the yogurt batch would be ruined.
The reason for sterilizing your equipment is simple. Unwanted bacteria already present can contaminate your batch. You could grow bacteria you didn't want along with the bacteria you did.
I fretted over this. I wanted to do everything right at least the first time. I really didn't want to go through all the effort and then have to throw it away.
When I can't get myself out of a hole, I ask the experts. I contacted the company I bought my cultures from. They responded quickly. Sterilization was not necessary. However, they recommended that I wash everything with warm, soapy water and let it air dry prior to making a batch. I could do that. If it's good enough for them, it's good enough for me.
Keeping the Oven Warm
Baking something in the oven without any heat went against everything I felt was right. You aren't cooking the yogurt though. You're incubating it, so the oven stays off. Cooking with the oven off? That's absurd! But, that's how you make yogurt.
How do you keep the oven at 108F without turning it on? That's where the oven light comes in. As hard as it is to believe, the oven light will keep the oven at the right temperature as long as the door is closed.
Getting the oven to 108F was the problem. One person suggested heating the oven on the lowest temperature possible for about 5 minutes, then turning it off to let it reach the right temperature.
I tried this, but found that our lowest setting is 170F. After 10 minutes of being shut off it was nowhere near 108F.
I found the best solution is to turn the light on and let it heat for about 2 hours. Using an oven thermometer, rather than the oven console temperature gauge, I was able to get an accurate reading on when the oven hit the right temperature.
If you find your oven is having trouble reaching the right temperature, replace the light bulbs. They may be too weak to create enough warmth.
Set the Oven to 108F
The oven must stay at a constant temperature (108F). Once you put your jar in the oven, cover it with a towel, and keep the light on. Do not open the oven door until it's time to do so. You will be surprise at just how warm the oven stays with just that little light working.
How Did My Yogurt Turn Out?
I let my first batch incubate for 7 hours since that was the minimum amount of time recommended and I was really eager. I was filled with anticipation and dread before pulling the towel off. It would either be edible or I wasted a whole afternoon for nothing.
I reached into the oven to pull out the jar. I was surprised at how warm the towel was. The jar was warm to the touch.
I pulled off the towel and was greeted by this wonderful smell. Oh my! No one told me homemade yogurt smelled so good! It smelled like warm baked bread. If the yogurt didn't turn out, I'd use it as air freshener.
At a closer look, the yogurt set perfectly. The top was smooth and solid looking, not milky and runny. It jiggled slightly when I moved the jar. There was some separation at the top, which is normal. And, there was no separation at the bottom which is bad news. Separation on the bottom means the batch is bad.
I covered it with the mason jar lid, then put it in the fridge overnight. This allows it to cool as the cultures continue the fermentation process.
I went to bed very pleased that my yogurt looked like it was supposed to. I'd know the next morning if it was edible.

There's a Cost Savings
Sometimes it just isn't worth the time, cost, or effort to make something yourself. Is there a cost savings making your own vegan yogurt?
I had to buy yogurt by the case. I got a case discount depending on where I ordered it from. The cost was about $5 per 1 quart container.
There were two ingredients in my yogurt. I used Silk Unsweetened Plain Soy Milk. A one gallon container costs roughly $3. Half of that is $1.50.
I purchased my yogurt cultures from Vegan Yogurt Starter These cost $8.99 for a box of 8 packets plus 3.99 shipping. 1 packet is used for 1 batch. This comes out roughly to $1.62 per batch.
My homemade yogurt cost about $3.12 per 1 quart. I saved about $1.75 per quart. Add that up over a year and it's a pretty good savings!
Note: I did have to purchase some equipment before starting. I needed a candy thermometer and an oven temperature gauge. That came to about $10 for both. You might even find them cheaper.
The Taste Test
It was all well and good that my yogurt looked right, but how did it taste? When I made my lunch, I brought the jar out of the fridge. It had been sitting about 15 hours before being opened. I removed the lid and there was that wonderful smell again.
I decided not to drain the "whey" (the liquid that separated at the top). Instead I stirred it in. This made my yogurt thinner, but that was okay. Not like I was entering the Yogurt Making Championships or anything.
It tasted pretty good. I would have liked a tangier taste. But, overall, it was a mild, pleasant taste. Not at all offensive.
I'd say my work was worth the effort. I successfully made homemade yogurt!
Note: After making about 9 batches of yogurt, I have decided that 13 hours incubation works best. This involves a little planning as I have to make the yogurt in the evening so it can incubate overnight. My 13 hour yogurt is full of flavor. It's much thicker than the shorter times. In fact, I was draining some of the whey in previous batches to get a thicker yogurt. With 13 hours of incubation, I do not have to drain it.
Physically, this process works out better for me. I wash my tools early in the day, then set them out to air dry. Sometime around 7pm, I start making my batch. Then, it's time for clean up. My arthritis thanks me for spacing out my standing time.
Does It Matter What Soy Milk You Use?
Can the brand of soy milk change how your yogurt turns out? Originally, I used Silk Unsweetened Plain Soy milk. However, they've changed their recipe replacing the carregeenan with gellan gum. It makes a difference. The new recipe produces a smooth, thinner yogurt that does not thicken.
I have tried Westsoy Organic Unsweetened Soy Milk. It has two ingredients: water and soybeans. The Westsoy sets correctly, making a thicker yogurt. It also has a more distinct, tangy flavor that I like. Each soy milk brand uses different ingredients.
Rule of thumb: The less ingredients and additives in your alternate milk, the better yogurt it will make.
Incubate for At Least 7 hours
Soy yogurt needs about 7 hours to set. The longer it sets the more flavorful and tangy it will be. You can adjust the time once you figure out how tangy you like it. I prefer 11-13 hours.
More Information for Making Your Own Yogurt
I am not going to take credit for figuring out this whole soy yogurt thing. If it wasn't for some great advice on the web, I would have never tried it myself. Below are the articles and videos I referred to before I made my first batch. I hope they'll help you, too.
