Groezinger beginning in 1870. It includes a wine cellar, distillery, stable, cream house and a former railroad depot.","why_significant":"The nomination argues the complex is significant for its link to large-scale wine production in Napa Valley, for its industrial brick architecture, and for its original owner and builder, G. Groezinger. It is described as the largest complex of brick industrial buildings in Napa County.","narrative":"Groezinger Wine Cellars is a cluster of brick industrial buildings in Yountville, Napa County, built from 1870 by G. Groezinger, a German-born wine merchant who came to California during the gold rush. The complex includes the two-story main wine cellar, a distillery, a two-story stable, a small limestone cream house and a railroad depot built about 1868 before his arrival. Most brick was made locally. It is described as the largest complex of brick buildings in Napa County. Groezinger built next to the railroad, planted many grape varieties and expanded his vineyard to over 402 acres, employing 42 people in wine making by 1883. Phylloxera and over-expansion cut production after 1889, and the Nevada Bank of San Francisco took the holdings in 1891. Since 1969 the buildings have been adapted into shops and restaurants, with changes intended to keep the historic structures intact. The property was listed for its role in Napa wine history and its brick industrial architecture.","period_of_significance":"1868-1872","architect_builder":"Unknown","architectural_style":"Traditional simple industrial style","criteria":[],"status_note":"Occupied and in use as the Vintage 1870 specialty shopping and restaurant center; condition listed as excellent, with alterations made for adaptive reuse.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:32.012618-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/82002218.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860028","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/california/napa-county/groezinger-wine-cellars-82002218/"}
