{{Short description|Coffee made by steeping grounds in cold water}} '''Cold brew coffee''', also called '''cold water extraction''' or '''cold pressing''', is a type of coffee prepared by the process of steeping coffee grounds in water at cool temperatures for an extended period. Coarse-ground beans are soaked in water for 12 to 24 hours.<ref>{{Cite web |url=https://bluebottlecoffee.com/preparation-guides/cold-brew|archive-url=https://web.archive.org/web/20180330043532/https://bluebottlecoffee.com/preparation-guides/cold-brew|archive-date=30 March 2018|title=Cold Brew Coffee Brewing Guide |publisher=Blue Bottle Coffee |year=2018}}</ref><ref>{{Cite web |url=https://handground.com/grind/beginners-guide-immersion-cold-brew-coffee |title=The Beginner's Guide to Immersion Cold Brew Coffee |website=handground.com |access-date=2018-11-14}}</ref>

The water is normally kept at room temperature, but chilled water can be used. After the grounds have been steeped, they are filtered out of the water using a paper coffee filter, or a fine metal sieve (e.g. in a French press), or felt. The result is a coffee concentrate that is diluted with water or milk, and is sometimes served hot, but often served chilled, over ice, or blended with ice and other ingredients such as chocolate.<ref name="cold-brew-process">{{cite web |url=https://coffee-brewing-methods.com/entity/cold-brew/ |title=Cold Brew Coffee |date=13 September 2020 |publisher=Coffee-Brewing-Methods.com}}</ref>

Nitro cold brew is typically served chilled but without ice, which would damage the foamy top.<ref name=":0" />
