What is coffee drinks and cold brewing coffee
Coffee drinks
are made by brewing hot water and, occasionally, cold water with ground coffee beans. The brewing is either done slowly by drip, filter, French press, cafetière or percolator, or done very quickly under pressure by an espresso machine. When put under the pressure of an espresso machine, the coffee is termed “espresso” while slow-brewed coffees are generally termed “brewed coffee.”
Cold brewing coffee
also called cold water extraction or cold pressing, is the process of steeping coffee grounds in water at cool temperatures for an extended period. Coarse-ground beans are soaked in water for about 12 to 24 hours.
The water is normally kept at room temperature, but chilled water can also be used. After the grounds have been steeped, they are filtered out of the water using a paper coffee filter, a fine metal sieve, a French press, or felt. The result is a coffee concentrate that is diluted with water or milk, and is even sometimes served hot, but often served chilled, over ice, or blended with ice and other ingredients such as chocolate.
Cold brew coffee originated in Japan, where it has been a traditional method of coffee brewing for centuries. Slow-drip cold brew, also known as Kyoto-style, or as Dutch coffee in East Asia (after the name of coffee essences brought to Asia by the Dutch), refers to a process in which water is dripped through coffee grounds at room temperature over the course of many hours. Cold brew can be infused with nitrogen to make nitro cold brew coffee.
Because the ground coffee beans in cold-brewed coffee never come into contact with heated water, the process of leaching flavor from the beans produces a chemical profile different from conventional brewing methods. Coffee beans contain a number of parts that are more soluble at higher temperatures, such as caffeine, oils and fatty acids. However brewing at a lower temperature for 24 hours results in higher caffeine content when brewed in equal volume compared to 6 minutes at 98 °C. The pH of cold and hot brew coffee is similar but cold brew coffee has a lower titratable acid concentration. Both pH and titratable acidity influence taste.

This brew is usually served in a clear liqueur coffee glass with the coffee and cream separated for visual and taste effect. The liqueur of choice is added first with a teaspoon of sugar mixed in. The glass is then filled to within an inch of the top with filtered coffee. Slightly whipped cream may then be poured over the back of a spoon, so that it floats on top of the coffee and liqueur mixture. The sugar is required in the coffee mixture to help the cream float.
