What Are The Oxidation Risks When Pressing Grapes? - Fine Wine Facts

Описание: What Are The Oxidation Risks When Pressing Grapes? Are you curious about what happens during the grape pressing process and how it affects the quality of wine? In this detailed video, we’ll explore the potential risks associated with pressing grapes and how winemakers work to manage them. We’ll explain the concept of oxidation and how exposure to oxygen can influence the color, flavor, and overall stability of the juice. You’ll learn about enzymatic oxidation, which can cause browning and off-flavors, and chemical oxidation, which impacts the wine’s aging potential and taste profile. Additionally, we’ll discuss microbial risks that can occur when oxygen encourages spoilage organisms to grow, potentially ruining the wine.

The video also covers the techniques used by winemakers to minimize these risks, such as rapid pressing, temperature control, and the use of protective agents like sulfur dioxide. We’ll introduce the practice of hyperoxidation, a controlled oxidation method that helps clarify white wines and reduce bitterness. Whether you’re a wine enthusiast or a budding vintner, understanding these processes is key to appreciating the art and science behind winemaking.
