Combine the peaches, honey, and rosemary in a large mason jar and muddle together with a large spoon. Cover and refrigerate for two days, stirring occasionally.
Blend the peach mixture, then strain back into the jar to remove any solids. Stir in the vinegar and refrigerate another three days.
To serve, fill a glass with ice, then pour in enough of the peach mixture to fill the glass about ¼ of the way. Top with sparkling water.
