oats milk

Oat milk is sold in a range of pack sizes from single-serve cartons (for example, 8 fl oz cartons sold in 6‑packs) to larger cartons and bottles (commonly 32 fl oz, 48 fl oz, 52 fl oz and 64 fl oz). Containers are most often paper/cardboard cartons or plastic bottles.

Shoppers most commonly use oat milk in coffee and lattes, with cereal, in smoothies, and for cooking and baking. It’s also used as a creamer substitute and for both hot and cold drinks.

Some oat milks are sold as ambient (shelf-stable) cartons that can be stored at room temperature until opened, while others are sold refrigerated. Most shelf-stable and refrigerated products will include a clear storage note—for example, “refrigerate after opening” or “store in a cool, dry place”—on the carton.

Portable options include small single-serve cartons (often 8 fl oz) sold in multi-packs for easy transport in a backpack or lunchbox. These are marketed specifically as on‑the‑go or travel-sized containers.

Oat milks are commonly fortified with calcium and vitamins A and D. Some product descriptions also highlight added soluble fiber or beta‑glucans.
