Sort the raspberries, working very carefully: Only perfect fruit should be used! Then pour into a wide-necked jar (e.g., a large cucumber jar).
Pour the vinegar over the berries. Close the jar and let it stand in a bright place for about 6 weeks, shaking it gently once a day.
Filter the finished vinegar through a muslin cloth and bottle.
Preparation Tip:
You can also use frozen raspberries.
