The vine is maintained by viticulturists from the Laimburg Research Centre and has been used to propagate new Versoaln vines to keep the variety from being lost to extinction. Wine is still being made from the Katzenzungen vine with fruit harvested from the old vine added to the fruit taking from the newer plantings of Versoaln. Between the Katzenzungen vine and the newer plantings, around 500 bottles of Versoaln wine a year is produced in specially numbered bottles.
