Do probiotic cultures withstand freezing? Should you freeze your beloved dairy?

Last week, I shared our updated Shelf Life Guide for Farm Fresh Food with you. And, gee, that sparked some wonderful conversations with readers. Great feedback.

Multiple people were surprised that I did NOT recommend freezing yogurt and kefir. Their anecdotal stories told a different tale, one where you can freeze yogurt and kefir at home with varying success.

For example, some said that they freeze both yogurt and kefir with good results. Some said that they don’t notice a difference between fresh vs. frozen kefir, but freezing yogurt didn’t work well. Some said that freezing Greek yogurt works because it’s thick, but thinner yogurts get clumpy when thawed.

The stories were a little inconsistent, but it showed me that freezing yogurt and kefir is possible.

It’s not an issue of safety; it’s an issue of quality. Frozen foods are technically safe to eat indefinitely. But, they will degrade depending on the type of food, storage conditions, and time.

There was one BIG outstanding question from these conversations - what about microbiology? Can probiotic cultures survive freezing? I did some research.

I looked closely at a few studies about probiotics and frozen yogurt and kefir (1) (2) (3) (4). I saw a trend. All the charts and graphs looked something like this:

So… it seems that probiotic bacteria can survive when frozen.

However, the population decreases over time. The longer yogurt or kefir is frozen, the less probiotic health benefits. At 2 months in the freezer, probiotic populations can decrease 15-50%.

The amount of probiotic decrease depends on a variety of factors. Here are a few:

The type of dairy product matters. One study showed that traditionally fermented dairy maintains its cultures the best over time (compared to those fortified with probiotics).
Adding an ingredient to the yogurt, natural or artificial, can increase or decrease probiotics.
The storage conditions and methods of thawing make a difference with quality loss.

So… if you want to freeze yogurt or kefir, you can certainly do so. Convenience and health benefits can be challenging to balance. This is a personal choice.

Where do you get your probiotics? Would you give freezing yogurt or kefir a try? Do you make any compromises when it comes to food and health?

I’d love to hear from you.Comment below (no account required) or contact us.

Eggnog's Medieval Magic

Well now, friends, let me tell you about eggnog - it's no yolk, this drink has been around forever! While history scholars are still whisking through different stories, most agree it sprouted from a Medieval drink called posset. Posset was hot milk curdled with wine or beer, served in a two-handled pot when folks caught the sniffles. Yup, that's right, I said sniffles. The warmth would settle your bones, the milk kept your strength up better than a day of plowing, and the alcohol and spices worked like nature's own medicine chest. Posset recipes were as varied as quilting patterns, every homestead had their own way to make it, and from this patchwork of kitchen wisdom grew a whole crop of milk based treasures, including... eggnog itself. Eggnog is a rich, chilled, sweet dairy drink that'll make you smile like you just finished morning milking. It's made with milk, cream, sugar, egg yolks, and spices, simple as that! Most folks only raise a glass during a short spell around Christmas. It was those fancy British folks in the 1700s who turned eggnog into a holiday tradition. They'd add expensive spirits and spices to milk to preserve it through winter (yep, aged eggnog, just like preserving pickles in the cellar). Eventually, eggnog crossed the ocean to the Thirteen Colonies. As times changed and food became easier to come by, common folk adopted it as a cherished holiday drink. Today, food is everywhere you look, but finding the right kind is harder than finding a needle in a haystack. Store-bought eggnog is stacked in every store, but I won't hitch my wagon to it. Store-bought eggnog is cooked up in factories to taste good and stay the same every time. But it's packed with additives, loaded with more sugar than a honey wagon, and has less than 2% egg yolks. Might as well call it milknog! And don't get me started on all that pasteurization business. If you've got the time, eggnog is easier than feeding chickens. Here's what you need: 4 egg yolks (fresh from the henhouse) ⅓ cup maple syrup (the real stuff, tapped honest) 2 cups raw milk (straight from Bessie, if you're blessed) 1 cup raw cream 1 tsp nutmeg (or whatever spices suit your fancy) 3 oz bourbon or rum (if you're of a mind to) You can mix these ingredients raw (like we do on the farm) or you can warm it up. Your barn, your rules. For a fuller eggnog, beat those yolks until they lighten like sunrise. Then fold in the rest. For a frothy eggnog that'll make you grin like a cat in the creamery, beat 4 egg whites until soft peaks form, then stir them into your finished batch. I highly recommend doing this whether you bought it from a farm stand or made it yourself. It's wonderful. So please, enjoy your eggnog this winter season. When you raise your glass, think on what you're celebrating. Toast to home remedies, good health, the wisdom of those who came before us, and honest food that comes from the land.

What’s really in a grocery store turkey?

It’s that time of year again—the turkey takes center stage. Whether it’s Thanksgiving, Christmas, or just a Sunday family dinner, a golden-brown bird is often the star of the show. But if you’re grabbing a conventional turkey from the grocery store, you might be wondering: what’s actually in it besides turkey? Why not add weird stuff to our holiday dinner? Many conventional turkeys are “enhanced” before they even make it to the freezer aisle. That usually means they’ve been injected with a solution of water, salt, and sometimes sugar or broth. It’s meant to keep the meat "moist and flavorful", but it also means your turkey may contain up to 15% of stuff that isn’t turkey. Always check the fine print on the label—you might be paying turkey prices for salty water. I sure hope you like your turkey with a side of salt! Those injections can leave a grocery store turkey surprisingly high in sodium. And when you see “natural flavorings” or “seasonings” on the label, it isn’t always just herbs and spices—it can also mean more hidden salt and flavor enhancers. So what exactly are these “boosters”? Think modified food starch for texture, “natural flavorings,” caramel coloring, and sometimes even MSG for that extra hit of savory flavor.Here’s the kicker: take a look at this turkey below—it’s sold by a major brand and proudly labeled ALL NATURAL. But read closely, and you’ll see it actually contains about 4% “other ingredients” that aren’t clearly listed. Makes you wonder, right? Turns out the real stuffing happens long before Thanksgiving—it’s all corn, soy, and unnatural junk. Conventional turkeys are typically raised on large farms where antibiotics may be used to prevent illness in crowded conditions. The USDA regulates withdrawal periods before processing (meaning the birds shouldn’t have antibiotics in their system at slaughter). So does that mean the birds really aren't antibiotic free after all? How confusing for the consumer! As for what the conventional turkeys are fed: Grains:Corn, wheat, and barley aren’t just wholesome-sounding grains—they’re the cheapest way to pack calories into a turkey, fueling rapid growth. Efficiency, not nutrition, is the goal here.Seed Oils:Soy, canola, and flaxseed are tossed in, not out of kindness, but to boost fat content and keep growth on track. Soy especially dominates, since it’s cheap and plentiful—most of it genetically modified. So these turkeys are definitely not low PUFA.Protein sources:Turkeys grow fast, and that means they need protein—lots of it. Beyond soy, feed mills mix in other plant-based proteins to supercharge growth in young poults. The formula isn’t about balance or natural diets; it’s about pushing birds to market weight as quickly as possible. Seed oils, sugar and more, OH MY! Certain “self-basting” turkeys may also contain a touch of sugar or dextrose, oils, or even phosphates to help retain moisture during roasting. My gosh this list keeps going on and on... And the star of the show... Conventional turkeys are genetically bred to grow quickly and large, especially in the breast area—because that’s what most shoppers want. It’s something Big Ag has down to a science: decades of selective breeding for size and speed at the expense of health and flavor. The result? A bird designed for profit margins, not taste. Compared to wild or heritage turkeys, today’s supermarket turkeys are bland, bloated, and bred to fit industry demand, not the dinner table. These turkeys don’t look much like wild turkeys anymore.
