My husband and I have been making our own yogurt pretty regularly since about 2010 when our sweet neighbor in San Diego introduced this great idea to us. At the time money was tight. I’d cook as often as possible but always bought yogurt at the store. I knew better than to buy the individual 6 to 8 oz small cups of yogurt because the bigger 32 oz tub was clearly a better deal. Little did I know that I could be eating something way better for way cheaper and that’s when I learned about the possibility of making my own. Our neighbor Del showed us which yogurt maker to buy and how to do it. Soon enough we were on our way to eating healthier yogurt that cost at least half of what we were spending.
It's been a few years and now I’m a bit of a yogurt snob. I haven’t quite gotten to buying my own lactobacillus bulgaricus et al concoctions, so from time to time I still buy some yogurt at the store to use as a starter. I refuse to buy anything with additives or added sugars because I’m a purist at heart when it comes to yogurt. Yogurt is just one of those magical foods rooted in simplicity.
About yogurt and the home made process
So let’s start with the basics. As far as ingredients go, all yogurt is—and is supposed to be—is milk and bacteria. The process that turns the liquid milk into yogurt is just a heating process: milk has to heat between 180-195 or even 200 degrees Fahrenheit and then brought back down to 110 degrees. At that point, bacteria is added to the milk usually in the form of a starter from another batch of yogurt. About a cup of yogurt is mixed into the warm milk and then the mixture sits in a comfy warm container for about 9 hours— a typical ‘work day’ for the bacteria. Afterward, the container goes in the fridge and once it cools down, voila! you’ve got yourself yogurt.
What’s really cool about this food is that it’s full of protein, calcium and probiotics and even has a bit of sugar, which is naturally there already from the milk. A cup of pure whole milk has about 11 grams of sugar, it’s just the way it is. Yogurt also has fats in it from the milk (mostly saturated fat), and whole milk makes the best kind of yogurt, especially when it comes to consistency. The fats in the milk help give yogurt that smooth creaminess to it, which can be enhanced even more by straining it for an hour or two. Straining removes the whey in the yogurt and leaves you with a bit of a “yogurt concentrate”, aka greek yogurt. All greek yogurt is is strained yogurt, which is why it’s more expensive: you need more yogurt to make the equivalent 8oz container. It also has more of everything (more fat, more sugar, more protein per ounce) so you don’t need to eat as much greek yogurt as you would regular yogurt.

Store bought yogurt
Ok, so back to my snobbery with yogurt. When our homemade yogurt sits in the fridge for more than a week, I don’t like to use it as starter because it doesn’t have as much useful bacteria that I can put to work later. We’re pretty good about making yogurt once a week or so but when we forget, we have to replenish the starter with a fresher batch of store bought yogurt.
Ideally I’ll make it to a fabulous store like Berkeley Bowl that offers plenty of choices. I usually buy organic yogurt and I devote time to looking at the ingredients. If the yogurt only lists two ingredients—milk and probiotics/bacteria— then I get it. If it starts listing crazy things like pectin, sugar, the evil, evil high fructose corn syrup, gelatin, citric acid, etc. I put it back on the shelf. When I’ve been in a bind and go to stores that don’t have a lot of variety, I’ve had to buy yogurts with things like pectin in them and my homemade yogurt just isn’t as good. A good, pure organic yogurt starter is essential to making great homemade yogurt.
But that’s only half the battle. Milk is just as important and should not be skimped on. I always opt for organic whole milk and I buy the whole gallon so I can make my 64 oz tub and use the rest of the milk in coffee/tea. If I feel like splurging, I’ll buy the really fancy milk like the Straus whole organic milk from grass fed cows that comes in a glass container but at 9 bucks per container, it’s not something I always do. Still, even then you’re more than breaking even if you compare the cost of a store-bought 32oz fancy organic plain yogurt to the cost of the milk, which will yield more than 64oz of fancy organic plain yogurt anyway.

Low-fat and yogurt marketing nonsense
When it comes to store bought, I also don’t even bother with the non-fat or low-fat yogurts. Almost every single one of them has added sugars to compensate for the lack of fats and to enhance the taste so now you’re eating something that is less healthy even though you think you’re eating a health food. I’d rather eat naturally occurring fats, aka whole plain yogurt, than added processed sugars, aka low or non-fat yogurt. I refuse to buy those branded flavored yogurt single-serving cups that pretend to be healthy; you might as well just eat a couple of spoonfuls of sugar and call it a day. If you want to eat yogurt because it’s healthy, I would avoid anything that isn’t plain. You can add fruit or honey to it at home and keep it healthy that way. I’m also weary of "extra-creamy/smooth" claims because there are usually additives that make that happen. For example, I was really excited when I saw a new yogurt at the store claiming to use a secret Australian recipe. When I was in Australia I ate yogurt like it was my job and I’ve missed it dearly. I could barely contain my excitement at the dairy section when I saw that we were finally getting Aussie yogurt in the States. To my surprise, however, this yogurt wasn’t pure goodness but instead had the pectins and gelatins I like to stay away from. So the lesson with plain yogurts is to always look at the ingredients and to just walk away if the list has anything other than milk and bacteria.

Anyway, if you want to save a couple of bucks on your grocery bill, eat a truly healthy product and stay away from additives, make your own yogurt at home. If it seems like too much of a hassle, at least do yourself a favor and get the good ol’ stuff with just milk and bacteria in it. Your gut will appreciate the friendly bacteria and your organs will appreciate taking a break from processing any extra sugars!
