1. Extraction: Hot water extracts more flavor compounds and caffeine from tea leaves or coffee grounds. This is because heat increases the solubility of these compounds, meaning they dissolve better in hot water. This results in a stronger, more flavorful beverage.
2. Sterilization: Boiling water kills bacteria and other microorganisms that may be present in the tea leaves or coffee grounds. This ensures a cleaner, safer beverage.
While cool water can be used to make iced tea or coffee, it will result in a weaker, less flavorful drink. Additionally, there is a higher risk of contamination from bacteria and other microorganisms.
Therefore, boiling water is the preferred method for making iced tea or coffee as it ensures a stronger, more flavorful, and safer beverage.
