Heat the water to 75–80°C (167–176°F), do not boil. Add the white tea and steep for 3–4 minutes. Remove the tea bags or strain the leaves and let the tea cool to lukewarm.
Add the dried hibiscus flowers and ginger slices to the warm tea. Let infuse for 6–8 minutes only, just until a deep ruby color and gentle spice develop. Strain out both hibiscus and ginger promptly to avoid harshness.
While the tea is still warm, stir in 2 tablespoons of honey until fully dissolved. Taste and add up to 1 additional tablespoon only if needed. Let the tea cool to room temperature.
Stir in the fresh orange juice. This provides sweetness and light acidity to balance the hibiscus and ginger.
Refrigerate for 1–2 hours until fully cold and integrated.
Fill glasses with ice, pour over the chilled hibiscus ginger orange white tea cooler, and garnish with orange wedges and optional dried hibiscus flowers.
