The Hop Press: A Memorandum of What's Brewin' was prepared by Hop Specialist G. R. Hoerner and issued monthly by the Oregon State College Extension Service as a means to provide information on hops and brewing to County Extension Agents in Oregon. The first issue was published in October 1948; it ceased publication with the March 1955 issue. This informal publication provides a detailed view of hops growing and production in Oregon and the northwest for this period. Each typewritten, mimeographed, 8-page newsletter includes a variety of announcements and news items regarding hops and brewing in Oregon. Statistics on hop acreage, the costs of production, and number of growers are available throughout. Information about the Oregon Hop Industry Research Advisory Committee, the Growers Advisory Committee, and other industry organizations is provided in the newsletter. Summaries and preliminary reports of hops research being conducted at Oregon State are included as well as news items from newspapers and other publications in Oregon and Washington. Agendas for Hop Growers Conferences and summaries of presentations at these conferences are also provided in the newsletter. The Hop Press includes information about hops growing in Washington, Idaho, and California and was distributed to individuals and organizations outside of Oregon.
Hop Pests and Their Control: A Report of the Control of the Hop Red Spider and Other Closely Related Problems During the Season of 1940 was written by H. E. Morrison (Assistant in Entomology) and J. D. Vertrees (Research Fellow for the Dow Chemical Company).
