What is nut milk and how is it made?

Quick answer

Nut milk is a plant-based drink made by blending nuts with water and usually straining out the solids. At home, soak about 1 cup of raw nuts for 4 to 6 hours, drain, blend with about 4 cups fresh water for 1 to 2 minutes, strain if you want it smooth, and refrigerate in a sealed container.

What is nut milk?

Nut milk is a dairy-free drink made from nuts such as almonds, cashews, pecans, hazelnuts or walnuts blended with water. Store-bought versions often add calcium, vitamins, stabilizers and sometimes sugar, so the label matters. Homemade nut milk has no added vitamins or calcium.

How is nut milk made at home?

Clemson University’s extension service gives this basic method:

  1. Ratio: 1 cup raw nuts to 4 cups water.
  2. Soak: cover the nuts with water for 4 to 6 hours or overnight to soften them.
  3. Rinse and blend: drain, rinse and blend with fresh water on high for 1 to 2 minutes until smooth.
  4. Flavor (optional): 1 to 2 tablespoons maple syrup, 1 teaspoon vanilla, a date, and a pinch of salt.
  5. Strain (optional): pour through a nut milk bag or fine sieve. Cashews often blend smooth enough to skip it.

Save the pulp for oatmeal, baking or smoothies.

How long does it keep?

Clemson says to keep it in an airtight container in the refrigerator and use it within 5 to 7 days. Homemade milk has no preservatives, so use it sooner if you are unsure. Separation is normal, so shake before use. Discard it if it smells sour.

Which nut should you use?

Nut Typical result
Almond mild, thinner
Cashew creamy, slightly sweet, little straining
Pecan rich, buttery
Walnut earthy, stronger flavor

Buying notes

  • Nut milk is low in protein compared with cow’s or soy milk.
  • It is not safe for tree nut allergy.
  • The CDC says plant milks should not be given to babies under 12 months.
