Homemade Cultured Buttermilk is going to be a game changer for you. It’s literally as easy as mixing two things in a jar.
And whoa are you going to love having all that fresh homemade cultured buttermilk around. Read or scroll through to the end for great ideas on how to use up your real buttermilk.
I use a lot of homemade buttermilk. And by ‘a lot’ I mean a ton.
Many of my baked goods contain buttermilk. Much of my salad dressing uses buttermilk.
And my beloved, The Evil Genius? He drinks buttermilk.
Now before any of you out there yawp with a resounding, “EW!” let me just mention that millions of Southerners and displaced Southerners are right now saying, “Mmmmmmmm! A nice tall glass of buttermilk with salt and pepper sounds mighty fine right now.”
A reminder: never yuck another person’s yum. Unless we’re talking durian, then all bets are off… (You may want to read about my family vs. Durian.)
We go through a lot of the stuff. And I may have mentioned that I live in the middle of nowhere in Amish country before (or a million times before, but who’s counting?) so frequent last minute trips to the store are not convenient.
How to Make Real Buttermilk
There are probably quite a few of you out there saying, “Oh please. All you have to do is add a little vinegar or lemon juice to milk and you get the same thing. Why buy buttermilk?”
See? I just knew someone out there was saying it. Not so fast! It’s not the same thing. To prove my point, I have to talk science for a moment.
While the acidified milk might give you the same tang of buttermilk, it lacks woefully in the texture and viscosity department.
Buttermilk is used in recipes for several important reasons. First, it is acidic, so it helps invigorate leavening agents -such as baking powder, baking soda and yeast- when added to baked goods.
The acid also helps combat discoloration in baked goods and promotes deep, beautiful browning. Buttermilk contains natural emulsifiers; this improves texture and aroma, and extends shelf life after baking.
The acidity of your homemade cultured buttermilk makes it a wonderful addition to marinades for chicken and pork. The acid helps tenderize the meat and gives it a tangy flavor.
Cultured Buttermilk
You know the ‘cultured’ part of cultured buttermilk? It’s good for you.
It contains many active cultures similar to those found in yogurt. Most of the cultures generally found in buttermilk are form the Lactococcus Lactis family and many of their subspecies.
Those cultures are what make homemade cultured buttermilk so thick and creamy. And what? Good for you!
Now that you know more than you probably ever wanted to know about buttermilk let’s get onto the ‘Why make my own?’ thing. Because you can.
Seriously. You need more than that?
Okay. Also make it because it’s dirt cheap, it’s super simple, it’s really fun and you’ll never run out of buttermilk again.
Hang on one second. Someone out there just said, “I never use a whole thing of buttermilk. What do I do with all that buttermilk?” I’m so glad you asked. How about a few of these ideas:
Perfect, flaky, Homemade Buttermilk Biscuit Take it from me, these buttermilk biscuits would do my Arkansas Grandma proud… They’re lofty, flaky, tender, and utterly divine.
Bacon and Swiss Rye Muffins These are every bit as good as they sound and as easy as pie. No wait! They’re easier than pie. Pie can be hard.
Grandma’s Buttermilk Cornbread This is my Grandma’s buttermilk cornbread recipe and it is ridiculously delicious and the ultimate comfort food.
Buttermilk Cornbread Rounds Based on my Grandma’s Buttermilk Cornbread recipe, these perfectly portioned cornbread rounds fit neatly in the hand and go anywhere cornbread goes, but look cuter doing it! This one’s going a little way back in the FWF archives.
Buttermilk Pancakes Nothing beats beautiful, light, airy buttermilk pancakes smothered in real maple syrup. Nothing. This one’s also reaching way back.
Garam Masala Depression Cake from Val. Nothin’ depressing about THAT cake, I’ll tell you. We’re talking about a decadent, Garam Masala flavored chocolate cake with orange buttercream and toasted coconut.
Oh my. I only take issue with the number of servings Val specified in it. It looks like a one-person cake to me.
I would be remiss if I didn’t mention these others…
- Chocolate Chip Breakfast Cookies (Drop scones)
- Extra Crispy Fried Chicken Fingers (The Evil Genius can cook!)
- Cornbread Salad
Are you good and hungry yet? Excellent. Let’s make some buttermilk. I promise it doesn’t take but two shakes.
Homemade Cultured Buttermilk
Scroll to the bottom for an easy-print version of this recipe!
Ingredients:
- 1/4 to 1/2 cup cultured buttermilk (from the store or home cultured)
- 1 to 2 quarts skim,1%, 2%, or whole milk from the store or raw milk
Also needed:
- 1 clean, dry quart or half gallon jar with a tight fitting two piece lid.
Okay. Ready? If you blink you’ll miss how to do it.
Pour buttermilk (1/4 cup for a quart jar or 1/2 cup for a half gallon jar) into your clean jar. Top off the jar with your plain milk.
Tightly screw lid to the jar and shake vigorously for 1 minute. Place in a warm (but not hot) area out of direct sunlight.
Let it sit there for 12 to 24 hours, until thickened. Refrigerate when thick.
Use within two weeks. If you re-culture this regularly, you can carry on re-culturing indefinitely.
Now here’s a glimpse of my finished product. Note that mine is super thick. I used raw, whole milk to culture my buttermilk. If you use skim, it may end up a little thinner than what you see here.

Reader's Thoughts...
Margaret Barnard says
I loved being able to do this but I left it a bit longer and it is REALLY thick, like yogurt. Can I still use it as buttermilk?
Rebecca says
Absolutely!! I’m betting you used whole milk, right? It’s just thicker 🙂
Bambi says
Can I use the whey from making yogurt and let that sit for 24 hours?
Rebecca says
I think it’s worth a try, Bambi! It certainly won’t hurt it!
Maejean says
My buttermilk has not thickened after 32 hours. What is wrong? It is getting a strong sour taste, not spoiled but no quite like buttermilk either.
Rebecca says
Hi Maejean- Let’s see if we can figure out what’s going on. What milkfat is the milk you’re using?
Erin Cooley says
Hi, I tried this using 2 quarts of whole milk and 1 cup buttermilk. After 30 hours, it had the consistency of milk. Just sour milk…not any thicker. Any suggestions?
Rebecca says
Hi Erin- What was the room temp where you had it sitting?
Karen Eastburn says
This is very handy right now because I can’t find much buttermilk at the grocery. Thank you! Could you be more specific as to what you mean by “reculture regularly”? Thanks!
Rebecca says
Sure thing, Karen! I’d say reculturing weekly will probably keep it healthy. Every other week at the outside edge. 🙂
Linda says
I make kefir and yogurt for the probiotic benefits. Does buttermilk also have probiotic benefits?
Rebecca says
Cultured buttermilk DEFINITELY has probiotic benefits!
Susan Burdett says
Good Day Rebecca,
Where do you get your original buttermilk from? We are unable to get cultured buttermilk from a store in Zambia.
Do you use the “old fashioned/ traditional” buttermilk which is drained from the butter churn or are you using the buttermilk from a store that is cultured with bacterial starter?
My main aim is to make cheese but we are unable to buy rennet or mesopphylic starter in Zambia so I am searching how to make these from scratch.
How can I make a mesophiliac starter to make cheese from scratch? they say use cultured buttermilk, but I am unable to get any cultured buttermilk. Please help if you can, would love a solution!
Thank you
From a real rural farmer
Rebecca says
Hi Susan- I use the cultured buttermilk from the store as a starter. Another good option for that would be to use yogurt if you can get that in the absence of cultured buttermilk. I’m afraid it’s going to be hard to make cheese minus a starter. Can you order powdered buttermilk or mesophillic starter from a mail order source and reconstitute it?
Selena says
So excited that I found this! We use so much buttermilk (mostly for waffles every day!), so this is such a help! Thank you for sharing!
Rebecca says
You’re very welcome!!! I’m so glad. I’m making more this week, too!
Debra says
Easy to understand directions. I just started drinking for stomach health. This would be great for cooking with more than drinking if it doesn’t have probiotics right? Thank you
Rebecca says
Hi Debra- Actually, you’re culturing it by doing this, so it does have the probiotics. I cook with it and my husband likes to drink it.
Michael says
I love buttermilk and have made it many times. I do the same as you but add a bit of salt. I am having a lot of trouble finding a decent starter brand. All the stores I use carry a cheap brand of buttermilk which tastes like liquid sour cream.
If you know of a website that I can order real genuine buttermilk culture I would be overjoyed to know of it.
By the way, God bless those who love a nice glass of buttermilk. 😇
Judy Walsh says
I apologize in advance if this has already been answered but with my computer when I try to scroll down the comments it jumps from place to place so I can’t check. My question is that I keep my apartment temperatures to 65 in the winter and 72 in the summer. Is there a way to reach the required temperatures to culture this buttermilk without needing to heat my entire apartment for so long a time?
Linda C Graybill says
I’ve been making this for a few years. If my store bought buttermilk is a little bit old or I don’t have much of the last batch made, I add 2 heaping tbs of plain yogurt, regular or Greek unflavored and follow the rest of the instructions. I drink 8-12 oz daily and really enjoy this so much and always have fresh cultured buttermilk in my refrigerator!! Glad you have added this so others can start their own brew.
Rebecca says
Thanks so much for your input and rating, Linda!
Nancy says
What do you mean by re-culture this. I am dumb.
Also would this give you probiotics?
Mary in Ohio says
My BUTTERMILK is brewing as we speak. I sat mine in oven with light on overnight. It feels warm..so I turned the light off and going to let it remain for a few more hours. My question is
CAN IT GET TOO WARM?
How will I know when its ready?
Thank you in advance
Rebecca says
Hi Mary! You’ll know it’s ready when it’s thick! If it doesn’t thicken as it cools, it may have gotten too warm or stayed too warm for too long. I suspect you’ll be alright, though!
Leon Shield says
I make my own sauerkraut. I got over the “will I poison myself”. Any chance on this with buttermilk?
Laurie says
Love this cannot wait to try to make it
Linda C Graybill says
I generally use 2% milk from the store. Same directions but I do add about 2 tbs of plain yogurt in addition to the cultured buttermilk. Yes, it certainly does keep going and going. If your last batch looks a bit weak, bite the bullet and buy a pint or quart of fresh cultured buttermilk from the store. Never hurts to freshen it up a bit. I have passed this info to so many people who drink it like I do, every day.
Rebecca says
That’s awesome, Linda! Thanks for weighing in with this helpful information!
LeeAnne Williams says
Can I use the buttermilk from what’s left after making butter from heavy whipping cream? Will that buttermilk have cultures?
Rebecca says
Hi LeeAnne- That is a different product. It’s confusing, I know, since they’re both called the same thing, but cultured buttermilk is not the same thing as ‘buttermilk’.
Nona says
I was looking for how to make homemade cultured buttermilk but after reading all the silliness through to the recipe, I see it isn’t homemade at all, but instead is a way to expand on existing, store-bought cultured buttermilk. The quest to find an original, homemade version continues. heavy sigh….
Rebecca says
Actually, Nona- it still is homemade cultured buttermilk as much as homemade yogurt still uses a starter culture. You can purchased a dried culture if you prefer, but this is the safest and easiest way to culture buttermilk. I see no reason not to capitalize on someone else’s propagation of all those lovely cultures that make milk products taste so good. 🙂
PHYLLIS WILLIAMS says
I AM 83 YEARS OLD AND WE DRANK ALOT OF BUTTER MILK WHEN WE WERE KIDS. (HOME MADE( AND GRANDPA MADE IT AND MY MOM. IT WAS NOT EVEN CLOSE TO HOW YOU DID IT. I DO REMEMBER IT TOOK SOME TIME TO MAKE IT, CAUSE WE KIDS WERE EAGER FOR IT, ALMOST ALLMORNING, BUT IT WAS WORTH IT. I DO REMEMBER THE BUTTER, SALT, AND WHAT THE ETC, I DO NOT REMEMBER.THANKS FOR LISTENING.
hAVE SOME AWESOME HOLIDAYS
PHYL
Rebecca says
Hi Phyl! I think what you had is actual ‘buttermilk’ vs. cultured buttermilk; you were drinking the result of buttermaking (which is considered whey now, whereas ‘buttermilk’ now generally means a cultured or clabbered milk product.)
