It is said that the array of options in Vienna’s coffeehouses was once so extensive that customers made their selection using a color code indicating the different brews. Austria’s neighbor Italy made its own contribution to coffee diversity by launching cappuccinos and the espresso on their triumphant march around the world. An entirely different innovation gave coffee another boost about 20 years ago: Pods and capsules made their way into coffee bars and home kitchens. They made it possible to prepare the beverage easily and quickly — and in controlled portions.
In recent years, new varieties of the venerable drink have reached the market. One example is Kopi Luwak, which is made from the beans that civets of East Asia eat and then excrete. The undigested beans undergo fermentation in the animal’s intestines, which gives the coffee an earthy, full flavor. But the countries of origin have increasingly been capturing civets and keeping them in anything but proper conditions, and the image of this specialty beverage has suffered.
Cold Brew in Bottles
In some of the most recent trends – since they are based on cold coffee – the beverage is making the transition from a stimulant to a form of refreshment. Brewing cold coffee involves pouring cold water on the ground beans and stirring. The brew then stands for up to twelve hours and is then poured through a filter. Without the use of hot water, hardly any bitterness or acid flavor is imparted to the coffee, yet it develops a rich aroma. Especially in warm weather, the beverage becomes a wholesome option when mixed with water, milk or ice. Cold brew has been sold in bottles for some time.
Today coffee is even available on tap – in the form of nitro coffee, a cold brew that is infused with nitrogen. This gives it a creamy consistency and a somewhat sweet flavor. It reminds some people of Guinness, a similarity reinforced by the drawing of the draft beverage in bars and restaurants. The experimentation with coffee has not run its course – far from it. In selected establishments of an American coffee house chain, customers can have their tea and cold drinks suffused with carbon dioxide. As a result, some customers have begun enjoying their coffee in carbonated form – which has tempted the company to consider an expansion of its product line. A small market has even emerged for a mixture of soda and coffee in the United States and Australia. The coffee is prepared as a hot drink and then cooled in a heat exchanger. Then sugar and carbon dioxide are added to the beverage, which is transferred into kegs and cans. These creative approaches to coffee are somewhat reminiscent of the craft beer movement.
