What is the difference between on-premise and off-premise?

On-premise is drinking at a licensed venue such as a bar or restaurant, while off-premise is buying alcohol from a shop to drink elsewhere. Some countries set different minimum ages for the two, often allowing supervised drinking before independent purchase.

Why do some countries have two different ages?

Several European countries set a lower age for low-strength drinks like beer and wine and a higher age for spirits. For example Germany allows beer and wine at 16 but spirits only at 18, reflecting a harm-reduction approach.

Why is the United States 21?

A 1984 federal law tied highway funding to a minimum purchase age of 21, so all states adopted it. It is among the highest drinking ages in the world for a country where alcohol is legal.

Where is alcohol banned entirely?

A number of countries prohibit alcohol for residents on religious grounds, including Saudi Arabia, Kuwait, and Libya. Some others restrict it to licensed venues for non-residents or ban it in specific provinces.

Is this list authoritative?

No. It is a simplified reference. Real rules vary by region within federations, by beverage strength, and change over time. Always check current local law before relying on any age limit.

How old you must be to drink, country by country

This reference shows the minimum legal drinking and purchase age in countries worldwide, split into on-premise (bars and restaurants) and off-premise (shops) limits. Many countries set a single age, but others vary it by venue or by how strong the drink is, all of which the table captures.

How it works

Drinking-age laws sit in each country’s public-health and licensing legislation. Two distinctions drive most of the variation. First, the venue: some places let younger people drink in a supervised restaurant setting before they may buy alcohol independently from a shop. Second, beverage strength: a common European pattern allows beer and wine at 16 but reserves spirits for 18, on the logic that high-alcohol drinks carry more risk for young people. A few states monopolise off-premise sales through government shops (Sweden’s Systembolaget, Iceland’s Vínbúðin) and set a higher purchase age there. Finally, some countries prohibit alcohol entirely for religious reasons.

Tips and notes

Where on-premise and off-premise ages differ, the off-premise (shop) age is usually the stricter one to watch.
The notes flag strength-based splits — check them before assuming a single number applies to spirits.
This is general orientation. Limits change, vary by region within federal countries, and depend on local enforcement, so confirm current law before relying on it.
