A "Stein" is a type of beer mug, often made of ceramic, glass, or metal, that is commonly used in Germany and other countries. These mugs typically have a handle and a lid, which helps keep the beer fresh and prevents spills. Many steins are beautifully decorated with intricate designs, showcasing German culture and traditions. Steins come in various sizes, but the most popular is the one-liter stein. They are often used during celebrations like Oktoberfest, where people gather to enjoy good food, music, and, of course, beer. Collecting steins has also become a popular hobby for many enthusiasts.
