The meticulous brewing process is at the heart of La Cafetire Cold Brew Coffee Maker's functionality, which involves steeping coarsely ground coffee in cold or room-temperature water for 12 to 24 hours. This extended steep time is the key to unlocking the full potential of the coffee beans, allowing optimal flavour extraction. The result is a smooth, concentrated cold brew that can be enjoyed on its own over ice or used as a base for a wide variety of refreshing iced drinks, from classic iced coffee to flavourful homemade fruit beverages.
