Language of Material: Collection materials in English.
During the vintage of 1905, Rudolf Jordan and Ernest L. Streich, owner of Castle Rock Vineyard, discussed the subject of making
better wines with particular attention directed to the efforts made at the University of California regarding pure yeast and
cooling of musts as advised by Professors Cruess and Bioletti.
Jordan later authored
Quality in dry wines through adequate fermentations by means of defecation, aeration, pure yeast, cooling and heating: a manual
for progressive winemakers in California
(1911) based on observations he made at Castle Rock.
Castle Rock Vineyard, located in Napa County, California was sold in March 1921 to H.G. March.
Scope and Content
Jordan's reports provide general remarks on the overall weather conditions, duration of vintage, general yield, condition
of grapes, yeast, and sugar in wines as well as a chronological description of the vintage at Castle Rock Vineyard from 1906-1918.
1918 was the last vintage described. In 1919 and 1920 the grapes were made into juice due to the passage of the Volstead Act.

as well as several newspaper and journal clippings, printed documents and pamphlets.
