means Coffee made by steeping coarsely ground beans in cold or room-temperature water for many hours (not minutes), then filtering — a process that extracts caffeine and flavor while leaving most of the bitter, acidic compounds behind.

from Not a modern marketing invention: cold-water coffee steeping has roots in Japanese Kyoto-style drip coffee, which dates back centuries, and in Dutch and Latin American traditions of steeping coffee overnight for travel and trade. The English term 'cold brew' itself is a plain compound — cold + brew — that simply describes the method, but it only became a retail buzzword and coffee-shop staple in the early 2000s to 2010s, when the slow-steeped style was marketed as a smoother, less acidic alternative to iced hot coffee.
