When people go for tea, a hot one in summer, seems only for elderly or women who are tea enthusiasts. Cold-brewing is the wise choice to taste nice while enjoy the benefits of tea. Brew the tea with cold water under room temperature or in the refrigerator, it extracts catechin first that contribute antioxidant and scavenge free radicals. Instead, cold-brewing draws fewer tannins into the tea than hot-brewing. Alternative to more bitterness with over hot-brewing, cold brew tea is naturally sweet, clean-tasting with little to no bitterness.
