Making Yogurt from Raw Milk: (Directions for Greek Yogurt Included)

Preview: Learn about making yogurt from raw milk with this picture tutorial. The instructions are for making regular yogurt and Greek yogurt.

No cows hang out in my backyard or the back forty. Raw milk is not available commercially in my town, but my son and daughter-in-law love yogurt made with raw milk. So they encouraged me to try it.

I may be entering treacherous territory. Recently I’ve had several inquiries about making Greek yogurt with raw milk (unpasteurized milk) on my Homemade Greek Yogurt post, so I decided to try it so that I can say I did.

Please note:  As a home economist, I’m not advocating adding raw milk to your diet. It’s a controversial practice not advised by the USDA. I encourage you to do the research.

Why do I need to heat the milk?

I have read that some people don’t heat their raw milk to 175˚F in the beginning, either because they want to save time or because they don’t want to kill certain bacteria. However, after doing side-by-side experiments, I observed that milk heated to 175˚F produces a thicker yogurt, whether raw or pasteurized at the outset.

High heat helps to unravel the proteins which aid the yogurt-making bacteria. However, I wouldn’t say I like to drink my yogurt, and I’m not comfortable letting unheated raw milk sit at 100˚F for 12 hours. So, I stick with the method for high heat, then a cool-down, before adding a yogurt starter.

As it turns out, making Greek yogurt with raw milk is the same process as pasteurized milk. What follows is a condensed tutorial. If you still have questions, check out my original post on making yogurt for more details.

How to make Greek yogurt with raw milk:

Heat the milk to 180˚F.

a clean, microwave-safe bowl and milk
Use a clean, microwave-safe bowl like this 2-qt Pyrex dish.
heating raw milk
cooling milk in a bowl of ice
Allow the milk to cool on the counter or speed the process by setting it on ice.


Allow the milk to cool down to 100-110˚F.

taking the temperature of the milk


Add a tablespoon of starter per quart of milk.

adding starter


adding starter
Whisk well, cover loosely, and set in a warm place. (100-110 degrees)

Once you prepare your yogurt by heating it, cooling it, and adding a starter, find a place in your house to incubate your yogurt. See this post for more ideas about how to incubate.


If you peek too often, too much heat may escape. Also, if you move or stir the milk mixture, the incubation process will stop, and no more thickening will occur.

After 10-12 hours, go to the next step. If you are not available at that time, it is OK to let it incubate for up to 24 hours based on my own experience. In general, the longer yogurt incubates, the tangier the yogurt.

See the pictures below for an example of what your yogurt should look like when it has finished incubating. We made three batches using different milk in each. First, the pasteurized skim milk was the thickest, followed by the raw skim milk. Finally, whole raw milk made the thinnest yogurt.

Pasteurized nonfat milk was the thickest.
comparing thickness of skim raw milk
Raw skim milk was thinner.
comparing thickness of raw whole milk
The whole raw milk was the softest.

Fifth: How to make Greek yogurt:

You could eat your yogurt at this point– once it chills, but if you prefer Greek yogurt as I do, proceed.

straining raw whole milk to make Greek yogurt
Use cheesecloth or a coffee filter to line a colander or sieve.
whey collected from yogurt
The liquid in the bowl is the whey drained from the yogurt.
whisking yogurt
After straining, use a whisk to whip the yogurt until smooth.

See how smooth and shiny our yogurt turned out. Of course, it will be even thicker when chilled.

If you chill the yogurt before straining, you may not need to use a cloth to line your strainer if your strainer is fine enough. Then, after 1-3 hours (your choice, depending on the yogurt itself and how thick you like it),  set the drained whey aside for other purposes and whip the remaining yogurt with a whisk. Use some muscle behind that whisk, and your reward will be creamy yogurt.

Add flavorings before or after chilling. Enjoy!

Making Greek Yogurt with Raw Milk

A guide to making your own Greek yogurt at home using fat-free, 1%, 2%, or whole milk.

Servings 8 servings


  • 1 quart unpasteurized dairy milk )
  • 1 tablespoon yogurt - commercial or your own homemade


  • Fill a Pyrex 2-qt microwave-safe bowl or pitcher with milk. Alternatively, pour milk into a heavy-duty pot to heat on the stove.
  • Heat in the microwave until bubbles begin to appear around the edge. The temperature should reach 170-180˚F after you stir it. (In my microwave, it takes about 11 minutes on HIGH). Check at 9 minutes.
  • Allow your milk to cool until the temperature drops to between 100-110˚F.
  • Whisk in fresh unflavored yogurt (the starter). You may use yogurt from a previous batch of your homemade yogurt.
  • Cover the milk and place it in a warm environment where the temperature stays around 100-105˚F.
  • Allow the inoculated milk to incubate for 4-8+ hours or until set.
  • At this point, you could chill the yogurt and eat it as is. Or you can decide whether to pour off the whey or stir it back in. Straining yogurt to make it thicker will result in Greek yogurt.

From Regular Yogurt to Greek Yogurt:

  • Carefully pour yogurt into a bouillon strainer or chinois. If the mesh is fine enough, you won't need to use a cheesecloth or paper towel. Or use a
    or a commercial size paper coffee filter inside a cheap strainer or colander.
  • Let yogurt sit in the strainer until the yogurt is reduced by approximately a third. Time will vary according to the thickness of the yogurt out of the oven and your own preference regarding texture and sourness.
  • Empty whey from the batter bowl and pour yogurt out of strainer back into the original bowl. Use a good whisk to beat until smooth. Thin with milk or leftover whey if yogurt is too thick.
  • Now is a good time to add any flavorings or sweeteners.
  • Chill.



Nutritionals are only an estimate. Numbers will vary according to how much you strain your yogurt.

Assuming raw milk has some good bacteria not normally found in pasteurized milk...

I'd love to make some yogurt using a mixture of any and all raw milk I can find (goat, cow, sheep, camel, etc), but I wonder if the bugs would play nice together? For example would one type of colony crowd out the rest when heated to make the yogurt?

Also, Mad Cow disease is so scary, is there any way to lower the number of potentially bad germs?

I'm not a food scientist so don't feel qualified to answer your question. So sorry. paula

You say that you are"not comfortable letting unheated raw milk sit at 100 degrees for 12 hours" but with raw milk to does not go bad. It just gets more and more sour. Raw milk is a living thing. I know someone who left raw milk out for several weeks to see what would happen. It never went bad.

Thanks for the info! A lot of people say that it is a complete waste to use raw milk if you will be pasteurizing it, but here in California the raw milk we can get comes from 100% grass fed cows, which to me is better milk than the stuff from grain fed cows. I think that the fat in the grass fed milk is of better quality.. Opinions?

My naturopathic doctor has cautioned me to not use the microwave for any food (now I use it to kill bacteria in a sponge). She says it changes the molecular structure of food and kills any nutritional value to it. Basically the food becomes a stomach filler but has no value to it. If you have not heard this before, research it online. Most of the Real Food websites do not recommend them. I started reheating food on the stove or in the oven, and it really does have more flavor to it.

wow. thanks for the how-to! i'm a bit confused though - this seems so simple, so why are there 'yogurt makers'? i was going to buy one on amazon, but it looks like it really isn't needed-?
