Term for the dry Wines of the highest level in VDP classification model (see the provisions there in detail). The spelling with "ss" instead of "ß" is intentional with a view to international marketing. It applies to all growing areas with the exception of Rheingau - here these are called First crop named. The Rheingau are an exception VDP members, since the 2013 vintage they have been able to call their top-quality dry wines from the "VDP.GROSSEN LAGEN®" also "VDP.GROSSES GEWÄCHS®".
The term "large plant" (but here with "ß") is also used in the association Bernkasteler Ring used, but has no connection with the VDP classification.
