Add fresh mint leaves and a lime slice directly into a rocks glass.
Gently press with a muddler to release the juices and essential oils.
Fill the glass to the top with large ice cubes.
Pour chilled ginger ale into the glass until it is about two-thirds full.
Measure 3.4 fl oz of chilled Mouton Cadet Rouge x Pierre using a jigger.
Slowly top off the glass with the wine to create a rich contrast over the ginger ale.
Garnish with an extra sprig of mint or lime wheel if desired and serve immediately.
