In a shaker combine all the ingredients. If you have included the blackberries, muddle well . Shake for 1 minute.
Pour and strain into a chilled glass. Optionally garnish with an herbal leaf, if available (such as lemon verbena, pineapple sage or wintergreen as suggestions). For a lighter, fruitier drink you could substitute 1 oz of the red wine with a fine pomegranate or cranberry juice.
