The term "Erstes Gewächs" in the Rheingau region refers to wines made from the best vineyard sites, signifying a classification that emphasizes quality and terroir. This designation is used primarily for dry wines produced from select, top-rated vineyards that have been officially recognized for their superior potential.

Wines labeled as "Erstes Gewächs" must meet stringent production standards, including restrictions on maximum yields and vinification processes, which further ensures their high quality.
