Cold brew coffee/tea originated from Japan. It’s known as mitsudashi. It’s said that Dutch traders learned of this method from the Japanese back in the 1600s, and experimented it with coffee to avoid open fire for brewing coffee on the long sea voyage. The result is the cold brew coffee we all love today. Contrary to cold brew coffee, famously known of being heavily caffeinated, cold brew tea actually has less caffeine and polyphenols compared to hot brew tea because of the low brewing temperature.
But since theanine aren’t prohibited by low temperature, cold brew tea still retains the health benefits and sweetness of tea, making this method an ideal iced tea preparation.
