Gently clean the strawberries by briefly rinsing them, or wiping them with a soft cloth. Cut large strawberries lengthwise into halves or quarters; leave small ones whole. Sprinkle the berries with sugar, and pour the wine atop. Serve immediately, or leave the berries to soak in the fridge for a few hours to allow the flavors to develop. These strawberries are delicious with a dollop of unsweetened whipped cream, or a scoop of vanilla ice cream.
