What is the legal drinking age in Costa Rica?

The legal drinking age is (informally) the minimum age at which people are legally allowed to purchase or consume alcoholic beverages in a given jurisdiction. Some jurisdictions set a minimum age on the customers licensed retailers of alcoholic beverages may sell alcohol to. Some set down a more comprehensive prohibition against persons below the minimum age being on premises licensed to sell alcohol. At its strictest, the term describes the age below which persons must have their alcohol intake properly supervised by those responsible for them, or are simply not permitted to consume it. Frequently these minimum ages will differ in a single jurisdiction. Legal drinking ages are sometimes tied to other age of majority laws, such as the right to vote, to consume other substances such as tobacco or marijuana, and may include exceptions in cases of medical need or parental consent, or more complex stipulations regarding kinds of beverages: some countries distinguish between drinks with lower alcohol-content (such as beer and wine) and stronger spirit-based drinks.
