Can You Freeze Unsweetened Almond Milk?

Almond milk's naturally occurring emulsion is less robust than dairy milk's, which is exactly why it doesn't hold together through freezing the way whole milk can — a frozen and thawed carton separates into a genuinely unusable, watery mess rather than something that just needs a good shake. With a 7-10 day opened window and no reliable freezer option, buying a smaller carton more frequently is a more practical habit than a large one that risks going unused past its window. A splash of frozen almond milk added directly to a smoothie, ice cube and all, sidesteps the separation problem somewhat by blending the separated components back together along with the other ingredients — a genuinely practical use for a small frozen portion that a straight glass of thawed almond milk doesn't offer.

Unlike dairy milk, which contains natural emulsifying proteins (casein micelles) that hold fat and water together reasonably well even after freezing, almond milk's fat content is stabilized mostly by added gums and lecithin — additives that do a fine job at fridge temperature but weren't designed to survive the physical disruption ice crystals cause, which is why the separation on thawing tends to be more severe than what a glass of frozen dairy milk shows.

Pouring into ice cube trays specifically to freeze small amounts for smoothies is sometimes suggested as a workaround, but it's worth setting expectations honestly — the cubes will still show the same grainy separation once blended, so this is a texture compromise for a smoothie's forgiving blend, not a genuine preservation method for drinking almond milk straight.
