What is the legal age to consume alcohol according to the Twenty-First Amendment?

The legal age to consume alcohol according to the Twenty-First Amendment is 21 years. This amendment, ratified in 1933, effectively repealed Prohibition, which had previously banned the sale and consumption of alcohol through the Eighteenth Amendment. As states began to regulate alcohol after the repeal, the legal age of 21 was established to promote responsible drinking and reduce the risks associated with underage alcohol consumption. The choice of 21 was influenced by research suggesting that younger individuals may not possess the maturity to make responsible choices regarding alcohol. Therefore, the Twenty-First Amendment indirectly led to a uniform legal drinking age of 21 across all states, which remains in place today.
