Our dry, hot summer days encourage the vines to set deep roots while the cold nights during the maturation period give the grapes their distinctive aroma. The adjacent Manhartsberg protects the gentle hills of the vineyards from cold winds, thus enabling the grapes to achieve optimum ripeness. Covering a total of 18 hectares, each of the of Zull vineyards has its own characteristics. Around Schrattenthal the Riesling is cultivated on mineral primary rock. In some places, the topsoil layer is only 20 cm deep, and directly below it lies the warming granite that gives the Riesling its delicate structure. Schrattenthal is also underlaid with well-irrigated sandy loess soils – ideal for the Grüner Veltliner and red wines. The clayey, loamy soils of the vineyards in Retz are tailor-made for the full aroma of Pinot Noir and Chardonnay.
