HARVEST WINERY INTERN 2021
Thumbprint Cellars is a winery and custom crush in the heart of Sonoma’s Alexander Valley seeking
driven, enthusiastic winemaking interns for this year’s harvest. This is a seasonal, hourly position,
beginning mid August 2021 and lasting through harvest (typically late October - early November). This is a
dynamic position which will provide valuable experience in the cellar as well as an opportunity to
work with numerous varietals, and winemaking styles. In addition to Thumbprint we house three
other brands, and interns will be exposed to both conventional and low-intervention winemaking
Our ideal candidates should have an interest in and high capacity for learning new things. They
should be fascinated by wine, have or be willing to develop a critical palate, and above all be
enthusiastic about working hard to create great wine! A love of loud music, ping pong, and cold beer
is a plus.
The Harvest Intern will be working closely with the Associate Winemaker and Enologist in making a
great vintage happen! Opportunities for both cellar and laboratory work are available, and we involve
interns in every aspect of the winemaking process, from tasting fermentations to managing
maceration and the harvest decision-making process.
