It's not just cold tea, it's Twig Tea. Cold brewing tea draws out different flavors than you're used to with hot brewing. You get fewer bitter catechins and caffeine, which makes the drink a little sweeter and smoother. Twig uses no herbal or fruit infusions, no sugar, and no teabags, just filtered water and loose-leaf tea. Choose from Darjeeling from India, Keemun from China, Oolong from Taiwan, and Bocha from Japan.
