About oenologist
The oenologist runs the winemaking process: setting the harvest date, directing pressing and fermentation, choosing yeast and temperature, managing filtration and stabilisation, and then deciding on maturation and bottling. Winemaking machinery falls to them as well — press, tanks, pumps, filters.
Tasting is part of the daily work. The oenologist carries out sensory assessment at every stage, recognises faults — oxidation, off aromas, excess sulphur — and decides on blending, bringing wines from different lots into one product with an intended profile. On that basis the oenologist advises the owner and buyers on the value and classification of the wine.
The oenologist manages the cellar's resources: space, barrels, tanks and the stock of wine in maturation. Standards are set for the production unit and detailed processing operations carried out. Formal requirements are set by the employer. Wine production is registered and inspected under national food and agricultural quality rules.
