At the turn of the 20th century, when Saar wine was unimaginably expensive, tobacco manufacturer Kern, from Saarlouis, owned a piece of vineyard land in Ayler Kupp. The vines are 70 years old today. After the sun has finished its work on the hot slate stones during the day, the coolness rises up the hillside from the marsh below and noticeably lowers the temperature. This interplay of scorching heat during the day and coolness at night is the secret to the intense aromatic expression of this off-dry wine.
