A wine press is a device used to extract juice from grapes during the winemaking process. Traditionally, it consists of a large container where grapes are placed, and a mechanism that applies pressure to crush the grapes, releasing their juice. This juice is then fermented to produce wine. There are various types of wine presses, including basket presses and bladder presses, each designed to efficiently extract juice while minimizing the extraction of bitter compounds from the grape skins. The choice of press can influence the flavor and quality of the final product, making it an important tool for winemakers.
