The legal drinking age is the age at which a person can consume or purchase alcoholic food or alcoholic beverages. These laws cover a wide range of issues and behaviours, addressing when and where alcohol can be consumed. The minimum age alcohol can be legally consumed can be different from the age when it can be purchased. These laws vary among different countries and many laws have exemptions or special circumstances. Most laws apply only to drinking alcohol in public places, with alcohol consumption in the home being mostly unregulated. Some countries also have different age limits for different types of alcoholic drinks.
The United Kingdom is the only country that has a minimum legal age for drinking alcohol in a home. Some Islamic nations prohibit Muslims, or both Muslims and non-Muslims, from drinking alcohol at any age. In some countries, it is not illegal for minors to drink alcohol but the alcohol can be seized without compensation. In some cases, it is illegal to sell or give alcohol to minors. The following list indicates the age of the person for whom it is legal to consume and purchase alcohol.
