Lab Intern

The QC / Lab Intern is a seasonal, hourly role that performs routine chemical and physical analyses across all stages of the winemaking process—from grape juice to finished wine and bottling samples—following established standard operating procedures. Working under close supervision, the position supports the Winemaking, Cellar, and Bottling teams by identifying, documenting, and communicating any issues that may affect product quality or packaging.

The role offers hands‑on experience in a production laboratory environment and contributes directly to maintaining consistent, high‑quality wine.
