Cold brew coffee is coffee steeped in cool or room-temperature water over many hours rather than brewed with hot water.
Smooth and rounded on the palate with a medium body, carrying strong roasted-coffee aroma, a mild bitterness, and notably less sharp acidity than hot-brewed coffee.
Bartenders build or shake it in as a base liquid or a coffee accent, adjusting strength by dilution since the purchased form is frequently a concentrate; undiluted it delivers far more coffee intensity and caffeine per volume. It is unsweetened as brewed, so any sweetness is added separately with sugar, syrup or milk.
Another coffee form works only where cold brew is a small accent; a hot-brewed coffee can approximate it but keeps a sharper acidity, and no non-coffee ingredient can stand in because the roasted-coffee aroma is the whole point.
Iced coffee
Iced coffee is brewed hot and then cooled or poured over ice, while cold brew never contacts hot water; the cold extraction gives cold brew a lower titratable acidity and smoother profile even though both are served cold.
Coarse-ground coffee is soaked in cold or room-temperature water for roughly 12 to 24 hours, then filtered off the grounds; the name refers to the brewing temperature, not the serving temperature. The initial product is often a concentrate meant to be diluted with water or milk before serving, and low-temperature extraction gives it a lower titratable acid concentration than hot-brewed coffee despite a similar pH. A nitrogen-charged variation, nitro cold brew, carries a creamy foamed head.
Refrigerate brewed cold brew and use within a few days, as it loses aroma over time.
