Ouzo 41% is a traditional Greek aperitif produced by the Kosteas Distillery in Kalamata, Greece. It is crafted following a traditional recipe that combines aromatic herbs, primarily anise, ethyl alcohol, and water.

It is recommended to serve it with ice or cold water, while storing it at room temperature is considered optimal; refrigeration is not advised. This drink is part of the Kosteas Distillery's range, which has been producing high-quality Greek beverages since 1962, including ouzo, tsipouro, liqueurs, and wines, blending traditional recipes with modern production techniques.
