3. United States – 21 Years Old
While in most states in the USA, the legal drinking age is 21, there are also some that have different rules from the common ones that have been set. For instance, it is illegal to purchase beer or wine in Idaho at certain time periods. In Kansas no alcohol can be purchased at all. It may differ from one state to another but the usual legal purchasing and drinking age is 21.
