Cold brew tea is a method of making tea by steeping tea leaves in cold water for an extended period, typically starting from at least 4 for a fresh taste to even over 12 hours for a stronger flavour. This technique differs from traditional hot brewing, where tea is steeped in hot water for a short time. High-quality tea can also be brewed for two more times using the same method. Cold brewing offers several unique benefits and characteristics, such as smooth flavour and low caffeine with enhanced sweetness and less acidity.
