Add the strawberries to a blender and blend until completely smooth.
Transfer the strawberry puree to a large mixing bowl. Add the heavy cream, sweetened condensed milk, sugar, salt, and Cabernet vinegar. Whisk until the sugar has completely dissolved.
Cover and refrigerate the mixture for at least 2 hours, or until thoroughly chilled. (This helps the ice cream churn faster and creates a creamier texture.)
Pour the chilled mixture into an ice cream maker and churn according to the manufacturer’s instructions until it reaches a soft-serve consistency.
Enjoy immediately for a soft-serve texture, or transfer to an airtight freezer-safe container. Press a piece of parchment paper or plastic wrap directly onto the surface, cover, and freeze for 2 to 4 hours for a firmer scoop.
