Purdue’s online Winemaking Certificate course is a streamlined, compact, yet comprehensive review of the principles and practices of commercial winemaking. It consists of six progressive modules that cover the ground from grapes to glass. Topics range from a critical review of winemaking techniques, styles and traditions to advice on aging, stabilizing, filtering, bottling and optimizing shelf life.

Each module includes a variety of video lectures and supplemental materials, as well as interaction with the instructor and other students. A comprehensive 100-question quiz that tests students’ knowledge at the end aims to apply what they’ve learned to their own winemaking endeavors. Butzke is available to advise on technical questions, even after participants complete the course.

“If they have an issue, suggestion or idea they would like to share with the other participating winemakers, they can openly or privately discuss it in my class,” says Butzke.
