After the First World War existed from January 10, 1919 to February 25, 1923, the German "Free State bottleneck", which in today's growing area Rheingau
was. The German provinces west of the Rhine were occupied by the Allies. In order to be militarily present also east of the Rhine, were by the victorious powers with Cologne, Koblenz (American) and Mainz
(French) semi-circular bridgeheads set up with a radius of 30 kilometers. Between the latter two there was an unoccupied area in the form of a bottleneck. The tiny Free State was cut off from the rest of Germany. To mark the 75th anniversary, the FFI (Free State Bottleneck Initiative) was founded in 1994 by committed winemakers and restaurateurs. Its members are committed to producing wines that are above the legal quality standards and to offer local food in conjunction with them.
