01 - Bring 4 cups of water to a boil. Remove from heat and let cool for 1 minute to prevent scalding the delicate white tea leaves.
02 - Submerge white tea bags in the hot water and steep for 3–4 minutes. Remove bags and allow tea to cool completely to room temperature.
03 - In a large pitcher, whisk together guava juice, fresh lemon juice, simple syrup, and 1/2 cup cold water until fully incorporated.
04 - Pour the cooled white tea into the pitcher with the guava-lemon mixture. Stir thoroughly to blend all flavors evenly.
05 - Taste the lemonade and add additional simple syrup if more sweetness is desired, stirring well after each adjustment.
06 - Refrigerate the mixture for at least 30 minutes to allow flavors to meld and beverage to reach optimal serving temperature.
07 - Fill glasses with ice cubes, pour chilled guava white tea lemonade over ice, and decorate with fresh lemon slices and mint sprigs.
