Tips to Freeze Milk and How to Thaw it Safely

Tips for freezing milk and thawing milk.

Please Share If This Helped You!

How can you save money on milk purchases? For years we’ve frozen milk that we bought on sale in our deep freezer, and then defrosted it when we were ready to use it. Freezing milk is not that hard to do if you follow our tips. Learn how we freeze and thaw milk safely and quickly.

The Smart Way to Freeze A Gallon of Milk

An important thing to remember when freezing milk is to pour off about 1 cup / 8 ounces of milk from the gallon before freezing. This allows “head space,” room for the milk to expand when it freezes. If you don’t pour off a little, when the milk expands, it can work its way out, pushing the lid off and make a real mess in your freezer . . . we know, we’ve experienced it.

In reality, we have never measured how much milk we pour off from the gallon. We just take the gallon of milk and pour enough milk into our currently open milk jug to leave about 1 1/2 inches of air space on the top of the gallon. Take a look at the photo on the top of the page to see how much milk we pour off of each gallon.

How long does it take to freeze a Gallon of Milk?

We’ve actually never timed how long it takes to freeze a gallon of milk. We put our gallons of milk on the bottom of our large chest freezer and then put bags of frozen veggies or fruit on top of the milk. At zero degrees Fahrenheit, it takes about 24 hours for a gallon of milk to freeze solid.

Does Milk Go Bad as it Freezes?

We’ve never had milk go “bad” while it was freezing. The normal storage temperature for milk is 40 degrees. In the freezing process, you are moving milk from 40 degrees Fahrenheit to zero. We regularly purchase milk that is nearing its “Sell By Date.” The Sell By date is the last day that stores are supposed to sell the milk. It is not the date that the milk “Goes Bad.”

When we buy milk that is close to the sell by date, we simply take it home and freeze it. It stops the deterioration. When it is defrosted we usually consume it within a week and rarely have it go bad. But if it does go bad, we use the sour milk to make “Sour Milk Pancakes.”  Get the recipe here.

How do you thaw frozen milk?

A website visitor wrote asked: I froze a gallon of 2 percent milk, it turned a yellowish color and it is taking forever to thaw. It’s been in the refrigerator for three days and it’s still frozen.

Here’s How We Safely Defrost Milk

To keep milk fresh it needs to be stored at 40 degrees Fahrenheit or colder. When we pull milk out of our deep freeze the temperature is about 0 degrees. To safely defrost milk we usually put the gallon container in our kitchen sink. Allowing it to sit in the sink to defrost is not a safety issue. The frozen milk in the gallon container keeps the milk that is defrosting on the outer edges at least at 40 degrees.

How Long Does it Take to Defrost Milk

In the winter, we pull the milk out the night before we need it and set it in the kitchen sink to defrost. In the summer, we do the same thing, but the process only takes a couple of hours.
If you’re nervous about spoilage, just shake up the gallon every half hour or so.

If we need to thaw it faster, we put it in the microwave for  5-7 minutes and then shake it and then put it in again until we have enough thawed out to use.
The milk doesn’t spoil because as it thaws it is cooled by the “ice” in the middle of the gallon. We’ve been doing this for at least 20 years and haven’t had any problems.

In the “old days” before the process of Homogenization was created, milk that was left sitting or had been frozen and defrosted would separate from the cream separate in the jug. Basically, the fat molecules would rise to the top of the liquid forming a layer of cream. The simple solution was to shake the jug until the milk was mixed back up.

Homogenization is designed to break down the fat molecules in a container of milk so that they don’t separate from the less fatty portion of the milk.

 

What Kind of Freezer do you Use to Freeze Milk?

A chest freezer is one of the most efficient ways to store food. They don’t cost a lot to buy or run and the amount of money you can save is amazing.

Check out the highest rated chest freezers on Amazon. And read this article where we describe what we freeze in our freezer and how much money it saves us each year.

Our first freezer was a used 9 cubic foot chest freezer. A few years later we upgraded to a 20 cubic foot frost free upright. Then when we moved to our larger home we sold the upright freezer and bought a 27 cubic foot chest freezer. It’s been working great since 1995 and saving us money every year since then.

Is It Okay to Drink Yellow Milk?

Frozen milk is not the pure white color that you normally see, it turns a little yellow. We had one mom tell us that she threw the frozen milk away because it “went bad” (turned yellow). Don’t fret if when it changes color; when defrosted it returns to its normal color and taste.

Freezing milk allows you to stock up on sale priced milk and not be concerned about it going bad before you use it. Drink up!

How Long Is Frozen Milk Good For?

Frozen milk will last for years with out losing any quality. As long as you keep it frozen and keep the lid tightly sealed to keep air out, it will store indefinitely.

Some websites say you should only freeze milk for between 3 and 6 months because it could absorb flavors from the freezer and because it turns more yellow. This is totally untrue. If you use sturdy plastic or glass containers, the flavor of your milk will not change if you store it longer.

As for turning “more yellow,” we’ve never seen that. The photo above proves that frozen milk does turn yellow, but it’s never gotten more yellow over time.

Please don’t be some uninformed bloggers scare you away from using your freezer to stock up and store milk and other great food bargains in your freezer.

What about Soy and Almond Milk—doesn’t it get lumpy and grainy?

We freeze all kinds of milk: Cow’s milk, Soy, Almond, Rice, and others. One thing we’ve noticed is that some of these products don’t freeze well. While they do freeze solid when you defrost them the liquid isn’t smooth . . . it’s grainy.

The solution to grainy defrosted milk

But there is a simple solution. Simply pour the defrosted milk into a blender and blend for about 10 or 15 seconds. It will be completely reconstituted. Check out this video and see for yourself

    I recently discovered that the 4-pack frappuccino bottles that look like milk bottles, hold about a cup of milk with adequate freezing headspace. The slightly larger bottles that are sold individually hold about a cup and a half. At that size they thaw quickly in a cold water sink bath, approximately half an hour. Since our kids moved out, we find we don’t need a whole gallon thawed at once but keeping recipe sizes frozen individually really helps us preserve and use our milk on our own schedule.

    How long is the milk good for after you have thawed it? How long have you frozen milk for and then used it? Thanks in advance 🙂

      Whitney, you have asked some GREAT questions about freezing and defrosting milk. While we’ve never really tracked the dates, we can tell you that we have successfully frozen milk for several months. When it comes to defrosting, its “shelf life” is the same as fresh milk – somewhere around a week if kept in the fridge at 40 degrees. We recommend not storing milk on the door of a refrigerator as it is one of the warmer spots due to opening and closing. If your milk does go sour after a week, don’t throw it out, just use it for sour milk pancakes – get the recipe here:Delicious Chocolate Chip Sour Milk Pancakes
