Location and Classification
Steingrube is a vineyard site on the Nimberg, also known as March hill. The site on the western slope of the Nimberg is connected with Neuershausen in March, as well as with Nimburg and Nimburg-Bottingen in Teningen. It is listed as a single site in the Kaiserstuhl area, in the Großlage Vulkanfelsen, in the wine-growing region Baden.
Soil and Climate
The Nimberg is a tectonic block in the Upper Rhine Graben and is not geologically part of the volcanic Kaiserstuhl massif. A thick layer of loess lies over Jurassic rock. For the vineyards in the Nimburg-Bottingen area, loess over shell limestone, red sandstone, and Rotliegend are also described. Geographically and climatologically, the Nimberg is assigned to the Kaiserstuhl wine-growing region.
Documented Wines
From the Nimburg-Bottingen Steingrube, a Blanc et Noir Sekt brut nature and an Frühburgunder red wine are documented. The Sekt is made up of 70 percent Spätburgunder and 30 percent Chardonnay. The Frühburgunder is also listed as a wine from the site.
Vinification and History
The documented Blanc et Noir is traditionally fermented in the bottle, subjected to a second fermentation in the bottle, and stored on the lees for around 48 months in the bottle before disgorging. The Frühburgunder is vinified by fermenting on the skins and matured for 14 months in barriques. Viticulture in Nimburg is already documented for the year 1463.
