Cold brew coffee

Coffee drinks are made by brewing hot water (or much less commonly, cold water) with ground coffee beans. The brewing is either done slowly by drip or filter, French press or cafetière, percolator, etc., or done very quickly under pressure by an espresso machine, where the coffee is termed "espresso"—slow-brewed coffees are generally regarded simply as "coffee". All coffee drinks are based on either coffee or espresso, in different strengths; some drinks have milk or cream added, some use steamed milk, cream plant based milk, or foamed milk, some have flavorings or sweeteners, some have alcoholic liqueurs added, some are combinations of coffee with espresso or tea.

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, then 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.

The caffeine content in coffee beans may be reduced via one of several decaffeination processes to produce decaffeinated coffee (sometimes known as "decaf" coffee), which may be drunk as regular, espresso or instant coffee.

Drip-brewed, or filtered, coffee is brewed by hot water passing slowly over roasted, ground coffee beans contained in a filter. Water seeps through the ground coffee, absorbing its oils, flavours and essences, solely under gravity, then passes through the bottom of the filter. The used coffee grounds are retained in the filter with the liquid falling (dripping) into a collecting vessel such as a carafe or pot. Paper coffee filters were invented in Germany by Melitta Bentz in 1908. To reduce waste, some coffee drinkers use fine wire mesh filters, which can be re-used for years.
