This course can be taken as a stand-alone course or as the first course in the Winemaking Certificate Program. Enroll in the course.

Note: The following four classes are limited in size to 40 students to ensure student/instructor interaction.

Unlike Introduction to Wine and Winemaking, these courses expect and require significant interaction with the instructor and fellow students in the form of readings, online discussions and written assignments, which you will submit via the Internet.

Wine Production
Quarter Academic Credit
4 X402.21

Please note: Due to high demand for the Winemaking Certificate Program, there is a waiting list of 3-6 months for this course. In order to be added to the waiting list for Wine Production you must first complete and submit an application. If you are accepted, you will be placed on the waiting list and you will be notified via email when there is space available in this course.

Along with a knowledge of wine and winemaking fundamentals, winemakers require an understanding of technical wine production. Through an online, interactive learning environment, this course reviews and explains the principles and practices of producing standard types of wines, with particular emphasis on the methods of vinification and their effect on wine style. Other topics include in-depth discussion of the alcoholic and malolactic fermentations and their management, as well as harvest and processing decisions for various styles of wines and common post-fermentation operations. By the end of this course, students will gain an overview of many technical aspects of wine production with an emphasis on fermentation management and pre-fermentation processes, options and strategies, and explore how the many winemaking decisions affect the resulting wine’s style.

Learning Outcomes

  • Comprehend technical reasons behind common winery operations
  • Manage yeast and bacteria in wine production
  • Understand the microbiological basis for problems occurring in wine production
  • Develop plans for treating and correcting problems arising during processing

Skills You Will Gain

  • Harvest criteria and impact on wine style
  • Must and juice processing
  • Yeast and fermentation management
  • Malolactic bacteria and ML fermentation management
  • Post-fermentation cellar operations

The curriculum of this course is closely based on the curriculum of VEN 124 Wine Production, the classroom-based course offered by the Department of Viticulture and Enology, UC Davis. You will receive the same lecture material as students in VEN 124 with the addition of online case studies augmented by student reports.

Quality Control and Analysis in Winemaking
Quarter Academic Credit
4 X402.22

Designed for current and future winemakers, this course is focused on wine microbiology and wine analysis and quality control. Students will learn both the theory and practice of winemaking analytical methods, when they should be used and how they impact the critical decision-making moments during winemaking.
