This Trollinger-Riesling crossing is named after the poet and physician, Justinus Kerner, from Weinsberg/Württemberg.
Winemakers and consumers took interest in the distinctive new crossing in the early 1970s. Starting in the Pfalz, the varietal spread to all German wine-growing regions. Its popularity peaked in 1992; however, since then, the number of plantings has declined. Today there are still about 3,500 hectacres of Kerner in Germany.
