2018 Harvest Intern - Trefethen Family Vineyards

Posting Date: 2/12/18

2018 Harvest Intern


Napa, CA

Company Name:

Trefethen Family Vineyards

Company Description:

We are a family owned estate winery in the Oak Knoll District with 450 planted acres. Our location allows us to successfully grow a range of cultivars including riesling, chardonnay, sauvignon blanc, pinot noir, cabernet sauvignon, cabernet franc, merlot, malbec, and petit verdot. In addition to our main ranch on the valley floor, we have a hillside property nearby devoted exclusively to Bordeaux varieties. We believe the best way to produce wines of the highest quality is to be in control of each step of the process from growing the grapes to bottling the finished wines. Our vineyard and winemaking teams work hand in hand to craft classic Napa wines that are a reflection of the Oak Knoll District.

Job Description:

Trefethen Family Vineyards is looking for enthusiastic and passionate applicants for our winery intern positions. The internship program at Trefethen runs from July until December, and includes exposure to all facets of wine production. The interns play a vital role in assessing vineyard block maturity, preparing the winery for harvest, receiving/processing fruit, monitoring fermentations, performing lab analysis, and gathering data to enhance the production of premium wines.

The internship involves extensive experience in both the laboratory and the cellar, as well as time in the vineyard. When working in the lab, the interns work closely with the winemaking team and are involved in all tastings. The internship includes significant independent work and is geared at preparing individuals for future careers in the industry. The responsibilities of the interns include:

- vineyard sampling

- crushing/pressing

- forklift operation (unloading trucks, loading the press)

- pumpovers/punchdowns

- fermentation monitoring

- general cellar duties (racking, filling, barrel work, sanitation, etc)

- bottling

- laboratory analysis of grape samples, musts and wines

- QA/QC operations

- setting up and participating in tasting and trials


Basic winemaking knowledge, completion of a wine chemistry course, valid CA Driver’s License, ability to lift up to 50 lbs, and ability to work long hours with a positive attitude are required.
