As you probably know, different countries have different legal age limits for drinking alcoholic beverages. In the United States, the age is 21. In some places in the world, there is no set age. In most places, the legal age is 18 to drink a non-spirit beverage such as beer in a public place without a guardian.
The map above, based on data from Wikipedia, shows where in the world you’re legally allowed to drink a beer in a public place. It’s slightly generalized and doesn’t take into account that in some places you have to be older to purchase the beverage, but it gives you a good idea of the age limits globally.
This by the way is part of new category I’m calling my sketchbook. I need a place where I can mess around with different formats without worrying about what is the “right” way to do it.
