Milk Kefir: 8 Reasons Homemade is Better than Store-Bought!

A few weeks ago I caved in and purchased a Milk Kefir Starter Kit from Cultures for Health. Let me say that I am so glad I did! After several months of buying quart after quart of store-bought milk kefir, I started to wonder about the benefits of making it from scratch. While I’m generally biased toward homemade processes anyway, my research into the benefits of homemade milk kefir over store-bought has exceeded my expectations. The list continues to grow, but for now, here are my 8 reasons why homemade milk kefir is better than store-bought:

1. You’ll Save Money!

A quart of store-bought milk kefir can cost upwards of $5. By making it from scratch you can reduce you cost by at least 50%! For example: a half gallon of organic, grass-fed milk costs $5 and yields 2 quarts of milk kefir…that’s $2.50 per quart! Use the milk you already have on hand and you’ll be making fresh milk kefir for less than half the price of store-bought! Furthermore, keep in mind that you only have to buy the milk kefir culture one time, since it can be reused over and over (see reason #4)!

2. You’ll Create Less Waste (i.e. Be Green)

I hate buying plastic. It is polluting when recycled, takes forever to break down in landfills (when not recycled), and inevitably winds up in the ocean. Bleh! I’m always trying to find ways to reduce my plastic consumption. By making homemade milk kefir I am eliminating all those plastic quart-sized bottles from our recyling bin and from the planet. Try culturing homemade kefir in wide mouth quart-sized mason jars!

3. Eliminate BPA and Plastic Toxins

We know by now that plastic leeches into our food and drinks. By culturing and storing homemade milk kefir in glass jars you can avoid unwanted exposure to BPA and other plastic toxins!

4. Buy It Once, Make Milk Kefir for Life!

When you buy milk kefir grains (not technically a grain, just what the culture is called) you can make an unlimited supply of milk kefir! By buying a Milk Kefir Starter Kit one time, you can make homemade kefir for the rest of your life! Milk kefir is the ultimate reusable culture.

5. You Can Make as Much or as Little as You Need

When you have your own milk kefir grains you can make only as much homemade milk kefir as you anticipate needing. If you want a few cups for a recipe, you can make just that much. If you need a half gallon, no problem. I can make as much milk kefir as I see myself using in a week and then make more fresh kefir when I’m ready for it!

6. Dairy allergies? No problem!

Another excellent thing about homemade milk kefir is that you get to decide what milk you use to make it. Milk kefir grains are quite versatile and can be used to culture cow milk (raw or pasteurized), goat milk, soy milk, or coconut milk, giving folks with lactose sensitivities plenty of options!

7. Homemade Kefir is Fresher

When your food doesn’t have to take a truck, train, or airplane to arrive in your fridge it is undoubtedly fresher! Make you own homemade milk kefir and you’ll get the freshest product possible. This also means that it’ll to me more rich in probiotics since some yeast and bacteria will die or weaken during the long trek that store-bought milk kefir must take to arrive at your grocery store.

8. Homemade Kefir is Richer in Probiotics

For the sake of consistency and shelf-stability, store-bought kefir is cultured using a powder starter which usually contains 7 to 9 strains of probiotic yeast and bacteria. Kefir grains, which are used for making homemade milk kefir can contain more than 50 strains of healthy yeast and bacteria! That’s a whole lot more than 7, folks. To be specific, homemade milk kefir is over 7 times more probiotic-dense than store-bought!

So there you have it! My 8 reasons why homemade milk kefir is so much better than store-bought. But don’t take my word for it. Try it for yourself with a milk kefir starter kit from Cultures for Health. Buy one HERE!

Curious what the process of making homemade milk kefir looks like? Check out this helpful video from Cultures for Health. Here’s a hint: you add the kefir grains to milk and let it sit out on the counter for a while….it’s that simple!

Get Started:



  1. Here is a suggestion you may want to pass along. I made approximately one cup of kefir in a jar for the “Magic Bullet” blender. It comes with a cover for straining fine particles which was perfect for straining the kefir from the cultures. I then added two table spoons of frozen blueberries and a tea spoon of sugar(because I like it sweet) Then blended it using the whipping blade. It turned out perfect. I then simply added milk back to the jar of cultures and started my next batch.

  2. Good points. I tend to bloat after drinking Lifeway Kefir–the best store bought I can find–and was considering purchasing some grains to make my own from 100% grass fed raw milk hoping to gain these marvelous benefits without the uncomfortable bloating. You just may have convinced me that it’s worth a try. (I hate to spend $ on the grains and still bloat, but if it works–yay :-))

    • There are actually great places where you can find milk kefir or water kefir grains for free. A lot of people believe in sharing the cultures for the health and well being of others, which means with a little patience you can usually get grains for free or the price of postage to send them to you!
