Let’s Talk About Freshness: Why Raw Milk Isn’t Meant to Last Forever

Raw milk is a fresh, living food—and like all truly fresh foods, it's not designed to last for months in the fridge.

Think about it this way: When you buy a pint of fresh, organic raspberries, you expect them to start molding within a few days, right? If they lasted two or three weeks, you might raise an eyebrow. Now imagine they stayed perfect for several months—that would definitely seem unnatural.

The same logic applies to raw milk.

Unlike heavily processed dairy products that sit on store shelves for 60, 100, or even 250+ days, raw milk is meant to be enjoyed fresh and regularly. It hasn’t been heat-treated, homogenized, or preserved to extend shelf life—and that’s exactly why so many people seek it out.

So, when raw milk starts to sour after a few days or weeks, it’s not “bad.” It’s simply doing what fresh food does. That natural evolution is part of what makes raw milk such a vibrant, nutrient-rich choice.

Whenever possible, aim to enjoy your raw milk as fresh as you can get it—direct from the farm, just the way nature intended.

We typically recommend drinking your farm fresh raw milk within 7-10 days of purchase.

Does Raw Milk Really Go Bad?

One of the most surprising things about raw milk is that it doesn’t "go bad" in the way processed dairy does. Unlike pasteurized milk, which often turns rancid and moldy after its expiration date, raw milk simply evolves—thanks to its natural, living enzymes and beneficial bacteria.

When raw milk begins to sour, it doesn't become harmful. In fact, this natural fermentation process has been embraced for centuries in traditional kitchens around the world. Rather than spoiling, the milk sours safely and can take on new, useful forms.

Many raw milk drinkers even look forward to this next stage—transforming soured raw milk into other nutrient-rich products like raw sour cream, clabbered milk, or even homemade cheese.

So instead of throwing it out, consider sour raw milk as an opportunity—not a waste.

Things to Pay Attention to

Bartlett Farms points out three important points to consider when storing and avoiding milk from spoiling.

1. Storing the milk

Most all of us can remember from science class that cold air is heavier than warm air. Warm air rises, so those bins at the bottom of our fridges are some of the coldest places to maintain food. So, when storing milk, it’s important to consider location. Placing milk on the bottom shelf near the back. One of the worst places to store milk for long term is in the door. If you plan to drink the milk quickly, placing in the door should not be an issue, but if trying to preserve the milk, consider placing in the coolest, darkest place in the fridge.

2. Secure lids

Keeping lids secure is important to the longevity of the milk. Milk starts to sour when the sugars in the milk are digested by the good enzymes and bacteria in the milk. The more the milk is exposed to air, the faster it begins to sour. So if trying to preserve the milk, avoid taking the lid off more than necessary.

3. Keep milk in same container

I’m not sure there’s a perfect container for raw milk, but we all know pouring the first glass of raw milk from a container can sometimes be a mess. However, when it comes to the freshness and longevity of the milk, try to avoid swapping milk into a different jar. By doing this, you take the risk of transferring the milk into a jar that may not be properly cleaned and sanitized, this can expedite the souring process of the milk.

What To Do When You Have Too Much Raw Milk

I was visiting with a friend the other day about milk — how some weeks it seems to disappear faster than we can blink, and other times it ends up sitting in the fridge longer than we’d like. 🥛 When it comes to raw milk, every drop feels precious. It’s the good stuff — straight from the farm, and in my perspective, a lot of work— and the last thing I ever want to do is let it go to waste. So here are some things I do when I need to use up some extra milk. Hot Chocolate or Latte’s Something about the colder months just calls for a warm drink in hand — a cozy cup of hot chocolate, or a creamy coffee or tea latte made with fresh milk. ☕️ And when summer rolls around, an iced tea latte hits the spot just right — cool, refreshing, and a whole lot better than most of those sugary summer drinks. Easy Hot Chocolate Recipe 1 cup raw milk 1 TBSP raw cacao 1 TBSP honey or maple syrup 1. Heat milk with a coffee frother or on the stove.2. Once at desired temp, add the cacao and the honey (maple syrup) to taste.3. Mix or whip until combined Tea Latte 1 tea packet or loose leaf tea of choice ½ cup water (can use less depending on cup size) ½ cup raw milk (can use less or more depending on cup size) 1-2 TBSP honey or maple syrup 1. Heat water and steep desired tea.2. Add tea to a cup with honey or maple syrup.3. Froth the milk and add to tea. Waffles I never realized how much milk a batch of waffles can take until I started making them for my boys. Around here, waffles disappear faster than I can stack them! 🧇 So now, on slower mornings, I mix up a big bowl of batter with our fresh raw milk and cook them up by the dozen. Once they’re cooled, I tuck them into the freezer—ready for those busy mornings when chores are calling and hungry boys come running. Nothing fancy, just good, wholesome food made from the milk our cows worked hard to give us. The recipe provided is courtesy of Thankfulhomemaking.com, however, multiple waffle recipes work as they all tend to use a good amount of milk. Butter Milk Waffles 2 cups flour 2 TBSP sugar 2 tsp baking powder 1 tsp baking soda ½ tsp salt 2 ½ cups butter milk – (to make butter milk add 2.5 TBSP vinegar or lemon juice to the milk) 1/3 cup butter, melted 2 eggs 1 tsp vanilla 1. In a large bowl, mix together the buttermilk and melted butter. Add the eggs and vanilla and mix well. In another bowl, whisk together flour, sugar, baking powder, baking soda, and salt. 2. Add dry ingredients to the wet ingredients and whisk until just combined. Then let batter rest while you preheat your waffle iron. 3. Pour batter into waffle iron and cook until ready 4. Extras can be frozen nicely for later use. Yogurt Yogurt is one of our favorite ways to put extra milk to good use. It’s simple, wholesome, and so versatile — perfect as a base for smoothies, a stand-in for sour cream in recipes, or just enjoyed on its own with a drizzle of honey and a handful of fresh fruit. There’s something special about that creamy, homemade goodness straight from your own milk supply. 🥛🍯 There are multiple ways that yogurt can be made and simply without any special kitchen appliances, however, one of my favorite recipes includes the use of an insta pot and is fool proof. Recipe courtesy of FarmHouseOnBoone.com Yogurt ½ gallon whole milk (raw in this case) ¼ cup yogurt culture or plain yogurt 1. Pour the ½ gallon of milk in the insta pot and press the “saute” button. Heat the milk to 180 while whisking constantly.2. Once the milk reaches 180, turn off “saute” option and allow milk to cool back down to 115.3. Add in ¼ cup of plain yogurt or starter culture and whisk into milk.4. Set insta pot for 8-24 hours on the yogurt setting. 5. Once the timer goes off you can transfer the yogurt to a container and chill or to make a little thicker, strain in a cheese cloth for up to an hour. Smoothies Without a doubt, smoothies are one of the easiest (though not always the tidiest!) ways to use up extra milk — especially when you’re blending for a crowd of hungry kids. The best part? The flavor possibilities are endless. Here are a few of our family’s favorite go-to smoothie combinations that never fail to please. 🥛🍓🍌 Chocolate Peanut Butter Smoothie 1 cup whole raw milk ½ cup raw milk yogurt (or plain regular yogurt) ¼ cup peanut butter 1 frozen banana 1 TBSP cacao powder 1. Place all ingredients in a blender.2. Blend until smooth and incorporated.3. Transfer to a cup to enjoy. Berry Smoothie 1 cup whole raw milk ½ cup raw milk yogurt (or plain regular yogurt) ½ cup frozen berries of choice 1 frozen banana 1 TBSP chia seeds, flax seed, hemp seed or whatever you may like 1. Place all ingredients in a blender.2. Blend until smooth and incorporated.3. Transfer to a cup to enjoy. I know there are a hundred other ways to put that extra milk to good use, but we’ll stop here for today. Maybe in the next blog, we’ll chat about soups and cream bases — perfect ways to keep every drop of that milk working for you. Until then, if you’ve got a little extra in the fridge, give one of these ideas a try and keep that precious raw milk from going to waste. 🥛✨

What To Do With Raw Milk Cream?

Raw milk cream is one of the richest, most versatile parts of farm-fresh milk — perfect for everything from sweet treats to nourishing everyday meals. Its natural flavor and nutrients make it a staple in any traditional kitchen. You can turn raw cream into indulgent desserts like homemade ice cream, whipped cream, or butter, or use it in everyday ways such as coffee creamer, oatmeal, or smoothies. In the kitchen, raw cream adds richness to sauces, soups, baked goods, and cultured creations like sour cream, clotted cream, or European-style cultured butter. For convenience, raw cream freezes well, though fresh cream makes the best butter. ✨ Whether whipped, churned, or cultured, raw milk cream is a wholesome, flavorful ingredient that brings old-fashioned goodness to modern kitchens.

Plastic vs. Glass Jars for Raw Milk: Which is the Best Choice?

When it comes to storing raw milk, the choice between plastic and glass jars makes a big difference in freshness, safety, cost, sustainability, and convenience. Freshness: Glass preserves raw milk’s clean flavor longer, while plastic can absorb odors and shorten shelf life. Safety: Glass is inert and easy to sanitize, but breakable. Plastic won’t shatter but can scratch, leach chemicals, and harbor bacteria. Cost: Plastic is cheaper upfront, but glass lasts longer, saving money over time. Sustainability: Glass is endlessly reusable and eco-friendly, while plastic has higher environmental costs. Convenience: Plastic is lightweight and practical for travel or families with children. Bottom line: Glass jars are the gold standard for keeping raw milk fresh, safe, and sustainable, while plastic works best for short-term convenience and portability.
