Scotch whisky is a timeless and sophisticated spirit that has been enjoyed for centuries. Whether you’re a seasoned connoisseur or a newcomer to the world of whisky, one question often arises: how long does a bottle of Scotch last after opening? The answer is not as straightforward as it may seem, as it depends on various factors that affect the whisky’s quality, flavor, and overall shelf life.
Understanding the Factors That Affect Scotch Whisky’s Shelf Life
Before we dive into the specifics of how long a bottle of Scotch lasts after opening, it’s essential to understand the factors that influence its shelf life. These factors can be broadly categorized into three main groups: environmental, storage, and handling.
