How is oat milk made?
Oat milk is made by mixing oats with water into a slurry, using hydrolysis to break down the starch, and then filtering it. The finished drink is usually heat-treated (UHT) so it can be stored at room temperature. This follows the University of Florida IFAS Extension publication on oat milk.

What are the steps to make oat milk?
UF/IFAS Extension describes the typical process as quite simple, in three steps:
- Slurry: rolled oats are combined with water.
- Hydrolysis: the mixture goes through a hydrolysis process that breaks down the starch. According to the publication, this prevents gelatinization and thickening at high temperatures.
- Filtration: the final step is filtration.
The final product is typically shelf-stable after ultra-high temperature (UHT) processing and can be stored at room temperature until the best-before date. UHT oat milk needs refrigeration once opened.
What is in oat milk?
The main ingredients are water and oat flour. Brands differ in what else they add, which may include vegetable oil, salt, stabilizers, vitamin and mineral blends, sweeteners and flavors.
Is store-bought oat milk the same as homemade?
The IFAS publication describes the commercial process only. It does not give a home method, and we did not find an official source for a home recipe, so we do not give one here.
What does oat milk contain?
IFAS says most unsweetened oat milks with no added oil provide about 90 calories per 1 cup (8 oz). Oat milk has much less protein than cow’s milk and more carbohydrate, and many commercial oat milks are fortified with calcium, riboflavin and vitamins A, D and B12. Nutrition varies from brand to brand, so check the label.
