A winemaker is a professional who oversees the production of wine, from grape selection to bottling. They are responsible for making decisions about fermentation, aging, and blending to create a desired flavor profile. Winemakers often work in vineyards and wineries, collaborating with grape growers to ensure high-quality grapes are harvested. In addition to technical skills, winemakers must have a good understanding of viticulture and oenology, the science of grape growing and wine making, respectively. They often taste and evaluate wines throughout the process, adjusting techniques as needed to achieve the best possible product.
