Pour your whisky, Creme de Peche and lemon juice into a tall glass filled with plenty of ice.
Top with chilled soda water and stir. Have a taste and adjust for sweetness or tartness. If you like it a little sweeter then add a teaspoon of sugar syrup and stir again. If you prefer it more tart add a little more lemon juice.
Garnish with a few peach slices or a twisted lemon or orange peel. Enjoy!
If you wanted a stronger drink you could top with chilled Prosecco or Champagne instead of soda water
For a sweeter cocktail replace the soda water with ginger ale
