Brew the tea according to the package directions, then let it cool completely at room temperature, about 20 minutes.

Whisk the honey into the warm tea while it is still slightly warm, so it dissolves fully without leaving grit at the bottom of the pitcher.

Stir in the peach nectar and lemon juice once the tea has cooled the rest of the way.

Cover and chill the mixture for a full hour, until it feels cold straight through when you dip a spoon in.

Fill eight glasses with ice.

Pour the chilled tea mixture over the ice, dividing it evenly among the glasses.

Garnish each glass with a thin peach slice and a mint sprig.
