Location and classification
The Kastanienbusch is a VDP.GROSSE LAGE in Birkweiler in the Pfalz winegrowing region in Germany. The classification as a VDP.GROSSE LAGE is an assessment by the VDP and not a designation under German wine law.
Topography and climate
The vineyard lies in a wind-protected, bowl-shaped hollow at the foot of the Hohenberg. With a south-facing aspect, it is situated at an altitude of 160 to 320 metres and has steep sections with slope gradients of 10 to 35 percent.
The south-facing aspect enables high daytime temperatures, while the altitude provides cooler nights and a large diurnal temperature range. The VDP links these temperature differences to an early bud break and a long ripening period.
Soils and grape variety
The classified vineyard area covers 29.00 hectares. The subsoil is described as red slate (Rotliegend), weathered Bunter sandstone, limestone with deposits of marly limestone (Kalkmergeleinlagerungen) and some fine earth. The VDP describes the Rotliegend as a skeleton-rich, iron-bearing slate rock and states that the site profile includes Rotliegend sandstone. For the classified site, Riesling is specified.
Wines
The Kastanienbusch wines provided by Ökonomierat Rebholz are Rieslings as VDP.GROSSES GEWÄCHS and are made dry. This includes the Kastanienbusch GG.
