After that failed attempt to manufacture wine in your bathtub, there's a way to escape the shame of defeat. Instead of bottling the rotgut you pressed with your feet, try bottling your own vino at Let's Make Wine in Delray Beach. This soon-to-be-national chain that started right here in South Florida lets customers mix their own wines to come up with unique blends, packaged with original labels. Owner Ann Rosenberg has plans to franchise her Delray Beach store across the country using the success pioneered by her late husband, Bill, founder of Dunkin' Donuts. Already, Rosenberg has opened a second store in Deerfield Beach and another in Colorado. The store allows customers to mix their own wine using pure juice or grape juice concentrate that's mixed with filtered water and bottled. The mix, which ranges from $160 to $319, makes about 25 bottles. Then the amateur winemakers create their own labels. Mostly, the idea has taken off as gifts for weddings and such, but Rosenberg says some customers just like having their own bottle of wine, without grapes between their toes.
