Von der Fels,’from the rocks’, is made using GG “cru” vines from 10 to 30 years old. 15 of Keller’s 18 hectares are classed growths. A peek at Grosses Gewaches complexity for a ludicrous price. About half of the production for this lovely bottling also hailed from the Kirchspiel vineyard, but from the chalky marl soils of the terres blanches section of the vineyard. The other half of the cuvée also comes from terres blanches soils, found in the lower sections of the other various grand cru vineyards: Hubacker, AbtsE and Morstein. One of the reasons that these lower slopes of these vineyards are not entitled to Grosses Gewächs status is that the soils here are deeper and richer, with more clay mixed in with the hard limestone.
