Grain teas are herbal beverages made from roasted grains, often enjoyed for their nutty flavors and health benefits. Common ingredients include barley, brown rice, and millet, which are toasted to enhance their taste. These teas are naturally caffeine-free, making them a popular choice for those looking to reduce their caffeine intake. In addition to their unique flavors, grain teas are rich in nutrients and antioxidants. They can be served hot or cold and are often used as a base for various blends. Many cultures, particularly in East Asia, have a long history of consuming grain teas for both enjoyment and wellness.
