Cereal-based drinks are beverages made primarily from grains such as oats, rice, barley, or corn. These drinks can be produced by soaking, grinding, and fermenting the grains, resulting in a nutritious liquid that often contains vitamins, minerals, and fiber. They are popular in various cultures and can be enjoyed hot or cold. These drinks can serve as a dairy alternative for those who are lactose intolerant or prefer plant-based options. Many cereal-based drinks are available in flavored varieties, such as chocolate or vanilla, and can be used in smoothies, cereals, or enjoyed on their own.
