Cold brew coffee is a type of coffee made by steeping coarse-ground coffee beans in cold or room-temperature water for an extended period, usually 12 to 24 hours. Unlike traditional hot brewed coffee, which uses hot water to extract flavors quickly, cold brew uses a slow, cold extraction process. This results in a coffee concentrate that is often diluted with water or milk before drinking. Cold brew is typically served chilled or over ice and has a smooth, mild, and sometimes fruity taste with less acidity and bitterness compared to hot brewed coffee. Key points about cold brew coffee:

• Made by steeping coffee grounds in cold water for 12-24 hours.
• Coffee grounds are coarsely ground.
• The concentrate is filtered to remove the grounds.
• Often served cold, over ice, or blended with other ingredients.
• Lower acidity and fewer bitter compounds than hot brewed coffee.
• Can be made into a concentrate for later dilution.
• Sometimes infused with nitrogen to create a creamy texture (nitro cold brew).

This brewing method produces a stronger, richer coffee with a different chemical profile due to the absence of heat, yielding higher caffeine content per volume compared to hot brewing methods.
