I had a third bottle of Sauvingnon Blanc left over and a fresh white peach. Did 2/3 oz of the other ingredients, added the Sauvingnon Blanc and stirred. Poured into a large wine glass and added slices of the fresh peaches. Wonderful.
Used Neisson rhum. Felt it needed a little more rum flavour. Added a float of Demerara Rum and it was perfect. Since it is summer, served with fresh cherries.
