Kostheim is one of the oldest wine-growing communities of the Rheingau. It is situated in the estaury of the rivers Rhine and Main in the heart of the high Rheingau region. The Romans were the first to cultivate wine here. The 120-hectare area is run today by the twelve local wineries located in Kostheim.
They grow predominantly riesling and pinot-noir grapes, but also other varieties such as Gewuerztraminer (a sweet and noble grape kind) and Chardonnay. This region has a microclimate which is influenced by the so called "Mainzer sink"; it allows the grapes to ripen arround two weeks ahead of the remaining Rheingau region.
Its beautiful old houses and alleys, friendly guesthouses and historical wineries make it also a place of interest.
