The collection includes documents such as meeting minutes, bank reports, certificates of shares and other ephemera.

The collection contains mostly paper documents, but there can also be found an audio recording, a few photo sets, some poster boards, and a medal. This collection was largely compiled by Susan and Bill Sokol Blosser over the years that they ran the winery. The records consist of mostly business, finance, and publicity, but there is also a plethora of information about the history and the day to day proceedings of the winery. Information on the wine, the vines, the buildings, the properties, the people, the associates, the business, and the founder are included in the collection.
