Combine the blackberries, water, and honey in a saucepan over medium heat. Bring to a boil while whisking constantly until the honey dissolves. Turn off the heat and let the mixture cool to room temperature, it will slightly thicken. This can be made in advance and stored in the refrigerator, up to one week.

Place the salt on a plate. Rim a glass with a lemon or lime wedge and dip in the salt to coat. Fill the glass with ice.

In a cocktail shaker, pour the tequila, orange liqueur, blackberry syrup, and rosé wine over ice. Shake vigorously. Pour mixture into the glass. Garnish with citrus, if desired. Cheers!
