Place mint leaves and sugar in a pitcher. Using a wooden spoon, mash leaves with sugar against side of pitcher to release flavour. Stir in bourbon until sugar dissolves completely. Cover and refrigerate to allow flavours to blend, at least 5 hours or up to half a day. Don’t worry if mint leaves darken because mixture will be strained.
Just before serving, fill glasses with ice. Strain bourbon mixture, then pour into glasses. Garnish each with a fresh sprig of mint.
