- 3 green tea bags
- 1/2 cup sugar
- 1-inch piece ginger, sliced, plus more for garnish
- 1 bottle prosecco (optional)
Put the green tea bags into a heatproof container and pour in 1 quart boiling water. Let steep until it comes to room temperature, about 1 hour. Remove the tea bags and discard.
While the tea is steeping, in a saucepan over medium-high heat, bring 1 cup water, the sugar, and ginger to a boil. Stir to dissolve the sugar, remove from the heat, and allow to cool to room temperature, about 1 hour. Store the tea and ginger simple syrup in the refrigerator until ready to serve.
