4. Course Description:

This course in the science and technology of winemaking is intended for the experienced intermediate winemaker, the winery employee interested in career development, or the advanced home winemaker that is seeking new challenges. Basic organic chemistry, microbiology, and some mathematics familiarity are recommended. There is a required 16-hour practicum component to this course. The purpose of the practicum is to provide students with hands-on experience in the winery by assisting in various winery operations. All students must identify a winery in their area that would be willing to serve a field practicum site and provide a mentor to guide the student during their hands-on experiences in their enology course.

2. Laboratory/Studio Sessions

There is a required 16-hour practicum component to this course. The purpose of the practicum is to provide students with hands-on experience in the winery by assisting in various winery operations. All students must identify a winery in their area that would be willing to serve a field practicum site and provide a mentor to guide the student during their hands-on experiences in their enology course. After identifying their mentor, the student should complete the online Field Practicum Site Form (link available on www.vesta-usa.org) by the end of the second week of the semester. Upon receipt of the form, the VESTA office will send a packet of information to the mentor explaining the field practicum, the skill sets to be completed by the student, and the mentor’s role in the field experience. The packet also includes a Student Assessment Form (SAF) for the mentor to fill out and send to the VESTA office at the conclusion of the practicum.
