Cashew milk is gluten-free — cashews and water, no grain.
Yes. Cashew milk is filtered water and cashews, plus gluten-free stabilizers and fortification. Cashew is a tree nut — not a grain, and not one of the gluten-containing grains (wheat, barley, rye, oats). Silk states its Cashewmilk is gluten-free; So Delicious is too. Verify cashew-oat milk blends (need certified GF oats) and unusual flavored variants. Cashew is a tree-nut allergen — a separate concern from gluten.
Cashew milk is gluten-free. Cashew is a tree nut — in the same group as almonds and walnuts — not a cereal grain, so it has no relationship to wheat, barley, rye, or oats. Plain cashew milk from major brands is reliably gluten-free; the only thing to check is cashew-oat blends.
What’s in Cashew Milk

Silk states its Cashewmilk is gluten-free. Per FDA labeling rules, none of these is a gluten-containing grain.

Frequently Asked Questions
Is cashew milk gluten-free?
Yes. Cashew milk is filtered water and cashews, plus gluten-free stabilizers and fortification. Cashew is a tree nut, not a grain, and not one of the gluten-containing grains. Silk states its Cashewmilk is gluten-free, and So Delicious cashew milk is gluten-free too.
Is cashew a grain?
No. Cashew is a tree nut (technically the seed of the cashew apple) — not a cereal grain like wheat, barley, or rye. Cashews, cashew butter, and cashew milk are all naturally gluten-free.
Are the stabilizers in cashew milk gluten?
No. Locust bean gum, sunflower lecithin, gellan gum, and the vitamin/mineral fortification in cashew milk are all gluten-free. None of the common cashew-milk additives contain gluten.
Is cashew-oat milk blend gluten-free?
Only if the oats are certified gluten-free. Some brands sell cashew-oat blends; oats are routinely cross-contaminated with wheat and barley unless specifically certified gluten-free. Check that the blend states gluten-free or uses certified GF oats. Plain cashew milk has no such concern.
Is homemade cashew milk gluten-free?
Yes, inherently. Homemade cashew milk is just raw cashews blended with water (often without straining, since cashews blend smooth). There are no gluten-containing ingredients. As long as your equipment is clean, homemade cashew milk is gluten-free.
Is cashew milk safe if I have celiac and a nut allergy?
Cashew milk is gluten-free and safe for celiac disease. However, cashew is a tree nut — if you have a cashew or tree-nut allergy, you must avoid cashew milk for that reason, entirely separate from gluten. For celiac without a nut allergy, cashew milk is a safe gluten-free dairy alternative.
