Add the white tea bags to the cold water in a large pitcher. Cover and refrigerate for 8–12 hours. Remove the tea bags without squeezing. The tea should be pale, soft, and never bitter.
Add the lemon peel strip to the cold brew tea and let infuse for 10 minutes only, just until a gentle citrus aroma develops. Remove the peel promptly to avoid bitterness.
Stir in 1 teaspoon of rose water. Taste and add up to ½ teaspoon more only if needed. The aroma should be delicate and airy, never perfumed.
Stir in 1 tablespoon of honey until fully dissolved. Taste and add up to ½ tablespoon more only if needed. This drink should stay light and dry, not sweet.
Refrigerate for 1 hour to fully integrate the aromas.
Fill glasses with ice, pour over the chilled cold brew white tea, and garnish with an optional twist of lemon peel.
