Can You Can Almond Milk

Yes, you can can almond milk at home, and it’s actually a great way to preserve it for months without worrying about spoilage.
 
If you’ve been wondering whether canning almond milk is safe or if it’s even worth the effort, the short answer is yes—with the right method.
 
Homemade almond milk can be canned using a pressure canner, which is the only safe way to preserve low-acid foods like nut milks.
 
In this post, we’ll walk through whether you can can almond milk, why pressure canning is necessary, the step-by-step process, and common mistakes to avoid so you can enjoy your homemade almond milk for months.
 
Let’s get into it.
 

Why You Can Can Almond Milk

You can can almond milk safely, but only if you follow proper canning procedures—and here’s why it works.
 

1. Pressure Canning Eliminates Harmful Bacteria

Almond milk is a low-acid food, which means boiling water baths won’t cut it.
 
You need a pressure canner to reach temperatures of 240°F (116°C) or higher, which is what kills botulism spores and other dangerous bacteria.
 
When you can almond milk using a pressure canner, you’re creating a shelf-stable product that’s safe to store at room temperature.
 
This is the same reason why you can can other low-acid foods like soups and stocks safely.
 

2. Proper Sealing Prevents Contamination

When you can almond milk in sterilized jars with properly sealed lids, you’re creating an airtight environment that prevents new bacteria from entering.
 
The heat from pressure canning also destroys enzymes that would otherwise cause the almond milk to spoil quickly.
 
So yes, you can can almond milk and expect it to last up to a year when stored correctly.
 

3. Homemade Almond Milk Is Perfect for Canning

If you’ve ever made almond milk at home, you know it’s fresher and more flavorful than store-bought versions.
 
But homemade almond milk spoils fast—usually within 3 to 5 days in the fridge.
 
That’s exactly why learning how to can almond milk is so useful.
 
You can can almond milk in large batches during almond season and enjoy it all year long without worrying about waste.
 

How to Can Almond Milk Step by Step

Now that you know you can can almond milk, here’s how to do it properly.
 

1. Prepare Fresh Almond Milk

Start by making fresh almond milk—soak 1 cup of raw almonds overnight, blend with 4 cups of filtered water, and strain through a nut milk bag.
 
Don’t add any thickeners or sweeteners yet, as these can affect the canning process.
 
You want clean, pure almond milk before you can it.
 

2. Sterilize Your Jars and Lids

Wash your glass jars and lids in hot soapy water, then sterilize them by boiling for 10 minutes.
 
Keep the jars hot until you’re ready to fill them because cold jars can crack when exposed to heat.
 
This step is critical when you can almond milk—clean equipment prevents contamination.
 

3. Heat the Almond Milk

Pour your fresh almond milk into a large pot and heat it to a simmer—about 180°F.
 
Don’t let it boil vigorously, as this can cause separation or scorching.
 
Heating the almond milk before you can it helps remove trapped air and reduces the risk of spoilage.
 

4. Fill Jars and Seal

Ladle the hot almond milk into your sterilized jars, leaving about 1 inch of headspace.
 
Wipe the rims clean, place the lids on, and tighten the bands finger-tight—not too tight, just secure.
 
This headspace is essential when you can almond milk because it allows for expansion during processing.
 

5. Process in a Pressure Canner

Place the filled jars in your pressure canner with 2-3 inches of hot water in the bottom.
 
Seal the canner, bring it to 10-11 pounds of pressure (adjust for altitude), and process pint jars for 75 minutes and quart jars for 90 minutes.
 
Once done, let the pressure drop naturally before opening the canner—this is non-negotiable when you can almond milk.
 

Common Mistakes to Avoid When You Can Almond Milk

Even though you can can almond milk successfully, these mistakes can ruin your batch.
 

1. Using a Water Bath Instead of a Pressure Canner

Never try to can almond milk in a boiling water bath—it won’t reach the temperatures needed to kill bacteria.
 
This is the number one reason people get sick when they can almond milk improperly.
 

2. Skipping the Headspace

Overfilling jars when you can almond milk can cause lids to buckle or seal failures.
 
Always leave that inch of headspace.
 

3. Not Cooling Jars Properly

Let jars cool undisturbed for 12-24 hours after you can almond milk.
 
Check seals by pressing the center of each lid—if it doesn’t pop back, it’s sealed.
 

So, Can You Can Almond Milk?

Yes, you can can almond milk safely using a pressure canner, and it’s a fantastic way to preserve homemade almond milk for up to a year.
 
You can can almond milk as long as you follow proper sterilization, heating, and processing steps.
 
The key is using a pressure canner—never a water bath—and making sure everything is clean and sealed correctly.
 
Hope this post has helped you understand how you can can almond milk at home and enjoy it for months to come.
