Cafe de olla, sometimes just called "Mexican coffee," is a traditional Mexican beverage that has been served for a very long time. It contains a mix of three spices (cloves, anise, and cinnamon) and a minimally-processed sugar called piloncillo. Traditionally, cafe de olla is made in an earthen clay pot, called an "olla," and served in similar clay mugs.

Turkish coffee, called türk kahvesi, is a sweet and delicious coffee drink locals love. It's made of very finely ground, unfiltered coffee beans and mixed with sugar right before the water boils to make it sweet. When the fine grounds are made correctly, it produces a frothy foam on top. Turkish coffee is traditionally made in brass or copper pots that are called cezves, and it's something that's meant to be enjoyed with others.

Of all the kinds of coffee in the world, you're probably most familiar with espresso, an Italian tradition. Espresso is made in machines that push pressurized steam through finely ground coffee beans to create a very strong coffee with froth on top. It's mixed with many other things, and in Italy, it's common to just have espresso with a little milk and sugar, or straight shots of it.

The preferred way of drinking coffee in France is simple: it's coffee with milk, which is what café au lait means. It's not just a latte or a cup of coffee with cold milk, though. Café au lait is brewed coffee mixed with steamed milk, and there usually isn't any foam on top.

This is definitely not your average cup of coffee. One of the most expensive coffees in the world, kopi luwak is actually made of coffee cherries that have been partially digested and then passed by Asian palm civets, which are Indonesian mammals. Civets, apparently, do not digest the cherries, but they do pick very ripe cherries for a great flavor. Once it's been collected, it's made in a French press, drip coffee maker, or espresso machine. It was once a luxury drink, but has become more popular, and is now often boycotted because of the inhumane conditions civets are kept in to produce the coffee.

It might sound similar to a frappuccino, but this very popular Greek beverage is quite different. The frappé is a refreshing summer drink made of instant coffee, water, sugar, and milk, if you like. It's shaken up pretty vigorously to create a nice foamy top, then poured over ice.
