Hoàng Trà is a Hanoi-based tea brand specializing in Trà Sen Tây Hồ, a traditional Vietnamese green tea naturally infused with lotus petals harvested around West Lake. The tea is made from high-quality leaves sourced from the Tân Cương region, which are repeatedly layered with fresh lotus petals so the leaves absorb a delicate, authentic floral aroma without artificial essences.
