What is cold brewing tea and how does it work?
Cold brewing tea is a method of steeping tea leaves in cold water for an extended period, usually 8-12 hours. This process allows the tea leaves to slowly release their flavors and compounds into the water, resulting in a smooth and refreshing tea. The cold brew method is different from hot brewing, where tea leaves are steeped in hot water for a shorter period. Cold brewing is a popular method for making tea, especially during the summer months, as it produces a tea that is less bitter and more caffeinated than hot-brewed tea.
The cold brew method works by using cold water to extract the flavors and compounds from the tea leaves. The cold water slowly breaks down the cell walls of the tea leaves, releasing the desired flavors and compounds into the water. This process is slower than hot brewing, which is why cold brew tea is typically steeped for a longer period. The resulting tea is often described as smooth, refreshing, and full of flavor, with a lower acidity and bitterness than hot-brewed tea.
