From Algerian syrup to Japanese cans, iced coffee is a global, multifaceted obsession
In short: Iced coffee is far more than just chilled caffeine. Whether it is the slushy caffè freddo of Italy, the condensed milk-infused cà phê sữa đá of Vietnam, or the double-strength brews of American chains, this drink has evolved into a diverse array of regional rituals spanning over a century.
The origins of cold coffee beverages are surprisingly deep. While menus in the late 19th century began featuring iced coffee, the Algerian beverage Mazagran, dating to around 1840, is often cited as the original version. By 1920, the Joint Coffee Trade Publicity Committee in the United States launched a marketing campaign that cemented its popularity. Today, the methods for achieving the perfect cup vary by culture and chemistry. Hot-brewing coffee at double strength is a common technique used by retailers like Starbucks to ensure that melting ice does not dilute the final flavor, though this method retains the acidity of traditional hot coffee.
In contrast, cold-brew coffee involves steeping grounds in lukewarm water for several hours to create a potent concentrate. This process is distinct from the Japanese method of dripping hot coffee directly over ice, which balances speed with dilution control. Beyond these base techniques, regional variations define the experience. In Chile, café helado incorporates ice cream and spices like cinnamon, while in Germany, Eiskaffee is a classic coffeehouse treat featuring vanilla ice cream and whipped cream. Greece offers the iconic frappé, created by shaking instant coffee, water, and sugar into a thick foam, a practice that gained global visibility during the 2004 Athens Olympics.
The market for iced coffee has also seen massive commercial expansion. In Japan, the 1969 release of canned coffee by UCC Ueshima Coffee revolutionized accessibility, making the drink available everywhere. Similarly, in South Australia, the Farmers Union brand has become so dominant that it reportedly outsells Coca-Cola. Whether it is the Dutch-influenced cold brew of Japan or the condensed milk-sweetened drip coffee of Vietnam, iced coffee remains a dynamic category. Between 2015 and 2016 alone, the popularity of these drinks in Canada surged by approximately 16 percent, proving that the global appetite for cold coffee continues to grow.
The diversity of the drink is further highlighted by unique local ingredients. Thai iced coffee often features cardamom, while Italian caffè in ghiaccio from the Salento region uses freshly brewed espresso poured over ice with sugar or almond milk. These variations demonstrate that iced coffee is not a singular product, but a versatile foundation for local culinary traditions.
