This hands-on, team-based role supports vineyard monitoring and sampling, then shifts to cellar and lab work including analysis, fermentation tracking, and production support. Designed as a strong stepping stone toward a future role in viticulture, enology, or assistant winemaking, the internship also includes a guided project that will be presented to company leadership.
