Muddle mint and peach in a pilsner glass. Pour Bourbon, coconut and lemon and fill the glass 3/4 way with crushed ice.
Place your stir spoon (with flat edge) in the centre of the crushed ice and rub the stir spoon in a rapid motion (this is how you swizzle). Fill the glass with more crushed ice and top with soda. Garnish with a mint sprig, peach slices and metal straw.
