To reduce waste, some coffee drinkers use fine wire mesh filters, which can be re-used for years. Paper coffee filters were invented in Germany by Melitta Bentz in 1908. The used coffee grounds remain in the filter as the liquid slowly drips into a collecting vessel, such as a carafe or pot. Water seeps through the ground coffee, absorbing its oils, flavours and essences as it passes through the filter. Infused Drip or filtered ĭrip-brewed, or filtered coffee, is brewed by hot water passing slowly over roasted, ground coffee beans contained in a filter. The caffeine content in coffee beans may be reduced via one of several decaffeination processes to produce decaffeinated coffee, also known as decaf, which may be served as regular, espresso or instant coffee. It then came to America, and with the rise in popularity of the Italian coffee culture in the 1980s it began to spread worldwide via coffeehouses and coffeehouse chains.

With the invention of the Gaggia machine, espresso, and espresso with milk such as cappuccino and latte, spread in popularity from Italy to the UK in the 1950s. There are many variations to the basic coffee or espresso bases. Upon milk additions, coffee's flavor can vary with different syrups or sweeteners, alcoholic liqueurs, and even combinations of coffee with espresso or tea. While all coffee drinks are based on either coffee or espresso, some drinks add milk or cream, some are made with steamed milk or non-dairy milks, or add water (like the americano).

When put under the pressure of an espresso machine, the coffee is termed espresso while slow-brewed coffees are generally termed brewed coffee. The brewing is either done slowly by drip, filter, French press, cafetière or percolator, or done very quickly under pressure by an espresso machine. Coffee drinks are made by brewing water with ground coffee beans.
