It seems you may be referring to Nieder-Olm, a town in the Mainz-Bingen district of Rhineland-Palatinate, Germany, rather than a specific event. Nieder-Olm is known as a wine-growing community in the Rhenish Hesse (Rheinhessen) region, located southwest of Mainz, and hosts local festivals such as its traditional wine and kerb (church consecration) celebrations.
