This course is designed for curious people who enjoy wine, especially wine from California and France, and would like to learn more about it. We will examine the connection between wines and their terroir—the complete natural environment in which a wine is produced—and learn why “place” and its geologic history—along with the grapes, their viticulture, the climate, and the winemaker’s skills—are all crucial to the characteristics of wines. We will explore the geologic setting of wine regions in California and France and, with comparative tastings, form the basis for understanding why certain grapes seem to prosper and others do not. As we delve into the geologic history of wine country, we will also learn about the geography, the wines, the names, and the history of numerous wine regions in California and France.

By the end of the course, we will have gained a better understanding of why wines are a reflection of “place” and have firsthand knowledge of many of the tastes that result. The wines we will taste will compare both Old World (France) and New World (California): Burgundy and California’s Chardonnay and Pinot Noir; Loire varietals such as Sauvignon Blanc, Chenin Blanc, Muscadet, Pinot Noir, Gamay, and Cabernet Franc; northern and southern Rhône wines such as Syrah, Grenache, Mourvèdre, and a dozen others; plus Bordeaux blends from California and France made of Cabernet Sauvignon, Merlot, and other Bordeaux varietals.


  • Course sizes are limited.
    You won't have 5,000 classmates. This course's enrollment is capped at 65 participants.

  • Frequent interaction with the instructor.
    You aren't expected to work through the material alone. Instructors will answer questions and interact with students on the discussion board and through weekly video meetings.

  • Study with a vibrant peer group.
    Stanford Continuing Studies courses attract thoughtful and engaged students who take courses for the love of learning. Students in each course will exchange ideas with one another through easy-to-use message boards as well as optional weekly real-time video conferences.

  • Direct feedback from the instructor.
    Instructors will review and offer feedback on assignment submissions. Students are not required to turn in assignments, but for those who do, their work is graded by the instructor.

  • Courses offer the flexibility to participate on your own schedule.
    Course work is completed on a weekly basis when you have the time. You can log in and participate in the class whenever it's convenient for you. If you can’t attend the weekly video meetings, the sessions are always recorded for you and your instructor is just an email away.

  • This course is offered through Stanford Continuing Studies.

Please note: Stanford Continuing Studies will offer a separate course excursion to Napa this Spring. The course, led by instructor David Howell, will review the 140 million–year history of the valley, the origin of the mountains and the valley itself, and the processes of sedimentation that characterize many of the valley floor vineyards. Participants will examine how elements of topography, climate, and soil, essential elements of terroir, have been used to subdivide Napa into fourteen distinct viticultural areas. The course will focus on Oakville, with vineyard and winery visits, along with tastings. Students will also meet with winemakers and vineyard managers. For more information, please see the Spring 2018 Catalogue (available in February 2018). While this course excursion builds upon Winter’s GEO 03: “The Geology and Wines of California and France,” each can be taken independently as well.

To participate in tasting discussions, students will spend approximately $160–$200 on California and French wines. A wine list will be provided at the start of the course. Students will taste the wines in advance of the optional online videoconferencing sessions (which will be recorded and posted). During these sessions, students will compare notes with the instructors and invited winemakers to discuss their experiences with the terroir, grape varieties, winemaking styles, and taste sensations.
