Institute for Grapevine Breeding Geilweilerhof

The Institute for Grapevine Breeding Geilweilerhof is a research facility in Siebeldingen focused on developing grape varieties that resist diseases and handle climate shifts. The facility includes extensive trial vineyards, laboratory equipment, and one of the world's largest gene banks for grapevine materials.

The facility grew from the need to develop grape varieties that protect wine regions from diseases and changing conditions. Over decades, it became a research center of international importance and is now recognized as a cultural heritage site in Germany.

The institute's work on grape varieties shapes how wine production evolves, with researchers collaborating with vineyards and regional wine makers. Visitors can see this relationship reflected in the experimental fields and displays that show how new varieties affect local wine culture.

Visitors can walk freely around the grounds from March through October and view the trial vineyards, with guided tours offering deeper insight. The best time to visit is during the growing season, when the grapevines are actively developing.

The institute developed Calardis Blanc, a white wine variety with natural resistance to multiple fungal diseases. This grape expresses flavors of passion fruit and blood orange, representing a new generation of varieties that are hardy without sacrificing taste.
