It stretches from the Rhine along the Leimbach into the side valley. With a slope of 65 to 70 percent, it is a typical steep slope. The name "hayn", dating back to the 14th century, referred to properties that were enclosed with a living hedge or hornbeam. The dark Devonian slate soils warm up easily and give off their heat to the vines in the summer in the evening and at night. In this way, the soils prolong the daily ripening phase. The terroir unit of the eastern part of the vineyard site on the Rhine produces particularly delicate, elegant Rieslings with a pronounced peach fruit. The Mittelrhein wine guide classifies this eastern part of the vineyard as a top site with the highest potential.
