As in many other countries, alcohol is legal in Germany. The most popular alcoholic drinks are beer and wine. It is a tradition to go to the local "Kneipe" (bar or pub) and drink alcohol with friends. Drinking is part of daily life for many adults and even allowed outside in public. In some areas (for example in trains) drinking is prohibited and marked with a sign. Children under 14 are not allowed to drink by law. In between the age of 14 and 15 they are allowed to drink beer and wine if accompanied by their parents. Strong alcoholic drinks are prohibited till the age of 18.
