Understanding Why Almond Milk Curdles

Almond milk is an emulsion – meaning the almond nutrients and oils are suspended in water. The proteins and fats naturally present in almonds do not dissolve fully in water. They are merely dispersed evenly, held together by emulsifiers which act like a “glue”.

Heat, acidity, age, and agitation can all cause this delicate emulsion to break, allowing the proteins and oils to clump together into curds which separate out of the water.

This quick separation of curds and whey is why almond milk can curdle so suddenly – the emulsion becomes destabilized.

Below are some of the most common triggers that lead to spoiled, curdled almond milk:


Adding an acidic ingredient like lemon, vinegar, or even natural yogurt can cause almond milk to suddenly curdle. The acid alters the pH, changing the electrical charges that allow emulsifiers to bind to the almond proteins. The emulsion breaks and separates.


Boiling, simmering, or even heating almond milk too hot when making hot drinks can denature the proteins and emulsifiers, making the emulsion unstable and separating out. This leads to clumping and curdling.


The emulsifiers and stabilizing gums added to commercial almond milk slowly lose effectiveness over time. Older almond milk is more prone to curdling when exposed to heat, acid, or agitation during cooking.


Vigorously whisking, blending or shaking almond milk can create enough friction and air incorporation to destabilize the proteins and oils, causing separation. Always handle almond milk gently!

Now let’s get into techniques for rescuing curdled milk and best practices for storing almond milk properly so it lasts as long as possible without curdling.

How to Save Curdled Almond Milk

Don’t pour that lumpy, curdled almond milk down the drain just yet! Here are four methods you can try to remix the emulsion and potentially save curdled almond milk:


  • Gently stir the almond milk using only a whisk or fork, not high speed blender
  • Attempt to evenly redistribute the curds back into emulsion
  • Works best on very mildly curdled milk where separation just started
  • Risks further damaging proteins and emulsion

Straining Out Curds

  • Pour through very fine mesh sieve or layers of cheesecloth
  • Catch and discard thick curd particles
  • Allows salvaging remaining thinner milk
  • Can result in lot of waste

Diluting With Water

  • Add a splash of fresh water and gently re-whisk
  • Water dilutes acidity or thins thickness
  • Allows emulsion to reform and proteins/fats to disperse again
  • Alters flavor and nutrition profiles


  • Transfer curdled almond milk to high speed blender or bullet
  • Blend 30 sec to 1 min to fully reincorporate
  • Best for severe curdling but risks over-blending
  • Can permanently damage proteins preventing re-emulsifying

The more separation there is, the harder it will be rescue the curdled almond milk. But it’s worth trying – I’ve saved many curdled milk that looked completely doomed!

If your attempts to remix the emulsion fail, the almond milk should be discarded. Using partially remixed milk can mess up recipes and risks food safety issues. Don’t take chances – when in doubt, throw it out.

Tips to Prevent Curdling

Prevention is easier than fixing curdled milk once it happens! Follow these best practices for handling and storing almond milk:

Purchase Fresh Cartons

  • Check dates and select farthest expiry when shopping
  • Avoid already opened cartons
  • Opened cartons have shorter life from oxygen exposure

Always Shake Well Before Using

  • Vigorously shake cartons for 30+ seconds before each use
  • Ensures emulsion is fully mixed every time
  • Allows stability when adding to hot dishes or acidic recipes

Don’t Boil or Overheat

  • Use medium-low heat when warming almond milk
  • Never bring to boil
  • High heat can denature proteins and emulsifiers

Add Acids Gradually

  • When adding lemon juice, vinegar or yogurt:
  • Mix in slowly, starting with small amounts
  • Whisk vigorously to help prevent curdling
  • Or mix acid with milk in separate bowl before adding to recipe

Store Properly

  • Keep refrigerated at all times, do not leave unrefrigerated
  • Seal container airtight to prevent air exposure
  • Use opened carton within 5-7 days
  • Freeze extras to extend life 30-90 days

Following these handling and storage methods will help maintain the emulsion integrity and prevent sudden almond milk curdling disasters!

What Causes Almond Milk to Curdle?

Almond milk is an emulsion, where the proteins, oils and insoluble elements from the almonds are dispersed in water, held together by emulsifiers and stabilizers.

This emulsion can easily become destabilized by:

  • Acidity – Lemon juice, vinegars, yogurt and other acidic ingredients alter pH levels and electrical charges, forcing the emulsion to break down into curds and whey
  • Heat – High temperatures from boiling, baking, or hot drinks can denature the proteins so they clump together rather than staying suspended evenly
  • Age – The older almond milk gets, the weaker the emulsifiers become at stabilizing the proteins, increasing odds of separation
  • Agitation – Vigorous blending or shaking introduces air and friction which causes the oils and solids to clump and curdle

The delicate balance of water, oils, proteins and emulsifiers that allow almond milk to remain smooth can be disrupted easily. Following proper handling and storage methods helps prevent the nightmare of suddenly curdled milk.

Can Curdled Almond Milk Make You Sick?

Consuming fully curdled, lumpy almond milk is not dangerous or likely to cause food poisoning on its own.

However, severely curdled milk left sitting allows more rapid bacteria growth which can eventually cause illness – faster than uncured milk. Always err on the side of caution and discard curdled milk showing any signs of spoilage like smell, taste, mold or sliminess.

Partially remixed milk is generally safe if it was freshly curdled – though the taste and texture will be less than desirable.

Again, when in doubt throw it out! Don’t take risks with curdled almond milk that looks or smells suspicious in any way.

When to Throw Out Curdled Almond Milk

Unfortunately, despite your best remixing efforts, sometimes curdled almond milk is beyond salvaging and needs to be discarded.

Here are signs it’s time to throw out the carton:

  • Curdled chunks remain and won’t incorporate after vigorous whisking and shaking
  • An off smell or taste develops – sour, bitter, rancid
  • You notice signs of spoilage – mold, sliminess, change in consistency
  • The almond milk curdled due to age or exposure – if it’s more than 7 days old after opening
  • Ifseparation occurred due to leaving carton unrefrigerated for many hours
  • If the almond milk curdled due to prolonged freezing – separation can be permanent

Don’t discard a whole carton of milk just because a bit first pours out curdled. But do throw it out if remixing methods completely fail to reincorporate the curds.

Trust your senses – if anything seems “off” about curdled almond milk’s look, smell or taste, do not consume it. Using spoiled milk is a food poisoning hazard.

When curdling happens, remix it immediately next time and refrigerate leftovers within 2 hours to stay safe. Prevention is the best solution.

Troubleshooting Curdled Milk In Recipes

Almond milk can suddenly curdle when added to recipes improperly. Follow these tips for a smooth, lump-free result:

Soups & Stews

  • Gradually whisk in almond milk off heat
  • Or temper by stirring in 1⁄4 cup slowly before adding full amount
  • Simmer only briefly once added

Coffee & Tea

  • Always preheat mug with hot water before adding milk
  • Pour milk first, then add hot drink second
  • Stir continuously to evenly disperse heat

Green Smoothies

  • Use fresh almond milk within 7 days of opening
  • Add ingredients in order: Liquids, leafy greens, fruits, powders
  • Avoid freezing smoothies containing almond milk

Hot Oatmeal

  • Cook oats first with water only
  • Turn off heat before mixing in milk
  • The less direct heat, the better

Mac & Cheese

  • Warm almond milk separately and add slowly to prevent curdling from heat and acidity
  • Or make sauce first, turn off heat, then mix in room temperature milk
  • Stir continuously until well combined

Baking & Desserts

  • Opt for thicker almond milk varieties to prevent curdling from high oven heat
  • Or sub a non-dairy creamer which holds up better baking
  • Be extra careful with acidic desserts containing citrus or vinegars

Hope these tips help you adapt recipes to use almond milk successfully without emulsion issues! Let the milk come to room temperature first when possible and always whisk vigorously upon mixing to prevent separation.

Shelf-Stable vs Refrigerated: Which Lasts Longer?

When purchasing almond milk, you’ll notice two varieties sold:


  • Found in the dairy aisle
  • Lasts 7-10 days refrigerated
  • More prone to curdling
  • Better flavor and nutrition


  • Stocked at room temperature
  • $Lasts 6-12 months unopened
  • Less flavor but won’t curdle as easily
  • Uses UHT pasteurization

The processing method makes a big difference in how well almond milk holds up. Here’s what to know:

Shelf-stable milk undergoes ultra high temperature (UHT) pasteurization, heating it hot enough to kill more bacteria for prolonged stability. The tradeoff is some lost nutrition and flavor from the intense heating.

Refrigerated milk has a shorter shelf life at peak quality, but usually retains more almond flavor, vitamins and minerals. It’s lightly pasteurized at lower temperatures.

If buying refrigerated, use within 7 days and freeze any extras for prolonged freshness. Shelf-stable packs can be stored conveniently at room temperature for months before opening.

So check your intended use – shelf-stable works well for baking and smoothies you won’t consume right away, while refrigerated is best for drinking and recipes where fresh taste matters.

How to Freeze Almond Milk

Storing surplus refrigerated almond milk in the freezer is great way to save it from spoiling. Here’s how:

  • Leave 2 inches of headspace in carton and seal tightly
  • Flat cartons freeze better than gable tops
  • Frozen almond milk lasts 30-90 days
  • Thaw overnight in fridge before using
  • Give very thorough shake once thawed
  • Use within 2-3 days of thawing

Freezing can damage milk proteins resulting in higher curdling risk once thawed. Always shake extremely well upon thawing and remix any curds that form post-freeze.

How Long Does Almond Milk Last Once Opened?

Like all plant-based milk, almond milk has a relatively short window of peak freshness once exposed to air by opening:

  • Refrigerated: 5-7 days
  • Shelf-stable: 5-7 days
  • Freeze extra: 30-90 days

No matter which type you buy, store opened cartons in a tightly sealed container in the fridge.

Exposure to oxygen and repeated temperature changes rapidly degrade nutrient levels and emulsion integrity. Storing opened containers properly is key!

Consume opened almond milk within one week. Look for signs like smell, taste, texture or separation to determine if it has soured. Freezing buys you more time.

Difference Between Almond Milk & Alt Milk

What exactly is the almond milk you see barrage of nut, seed and grain “milks” filling supermarket shelves these days? Here’s a breakdown:

Almond Milk

  • Made from blanched almonds + water
  • Most popular plant milk variety
  • Nutty flavor, creamy texture
  • Can be sweetened or unsweetened

Alt Milks

  • Plant-based milk alternatives like:
  • Oat milk
  • Soy milk
  • Cashew milk
  • Hemp milk
  • Rice milk
  • Coconut milk

All contain:

  • Plant base + water
  • Emulsifiers/stabilizers
  • Vitamins/minerals
  • Flavorings


  • Vegan/dairy-free
  • Low calories and carbs
  • Provide nutrients
  • Certain protein/healthy fats
  • Lactose-free

In summary, almond milk is one type of “alt” milk – referring to the exploding category of plant-based milk alternatives flooding grocery stores.
