Put a Cork In It
It's not just cheap, supermarket wine that tastes vinegary. Expensive, aged bottles of wine can spoil and end up tasting like kitchen-shelf vinegar. Here's why:
Any wine can turn to vinegar if oxygen gets inside the bottle and reacts with the alcohol. This happens when a cork is defective, of poor quality, or when wine is stored upright instead of on its side. The storage position is crucial because to keep out oxygen, a cork must remain wet. If you buy old wine at your local liquor store, you can make a good guess as to the wine's condition based on what you see.
Quality Control
But wine-gone-to vinegar isn't a chance you have to take. Not since a couple of chemists designed a way to place an unopened bottle of wine into a nuclear magnetic resonance spectrometer. Normally this device is used to determine the chemical contents of a small tube of liquid, as well as to examine nuclei in the human body, but they have adapted the instrument so it can detect vinegar even before it reaches the official level required to call a wine spoiled.

As an oenophile and wine enthusiast with a deep understanding of the intricate world of wines, I bring forth my expertise to shed light on the complexities of wine preservation and the potential pitfalls that even the most seasoned wine connoisseurs may encounter. My passion for wine extends beyond mere appreciation, delving into the scientific nuances that govern its aging, storage, and the crucial role of corks in maintaining its integrity.
In the realm of fine wines, the article's assertion that both inexpensive and high-end bottles can succumb to a vinegary fate underscores a universal truth in the wine industry. The culprit, as highlighted, is the infiltration of oxygen into the bottle, leading to the undesirable transformation of the elixir into something akin to kitchen-shelf vinegar. This chemical reaction occurs when the alcohol in the wine reacts with oxygen, an eventuality that can be triggered by defective or poor-quality corks.
The significance of proper storage conditions cannot be overstated. Storing wine upright, as opposed to on its side, is identified as a potential pitfall in the battle against oxidation. The necessity for a cork to remain wet is emphasized, as this moisture creates a barrier against the intrusion of oxygen. This simple yet crucial detail in storage practices can be the difference between preserving a fine wine's delicate flavors and experiencing the disappointment of a spoiled vintage.
Quality control measures have evolved to mitigate the risk of encountering a spoiled bottle of wine. Enter the innovative solution proposed by chemists who devised a method involving a nuclear magnetic resonance spectrometer. Traditionally utilized to analyze the chemical contents of liquids in small tubes and examine human body nuclei, this adapted instrument now serves the purpose of detecting vinegar within an unopened bottle of wine. This groundbreaking approach allows for preemptive identification of spoilage, enabling consumers to make informed decisions about the quality of their chosen vintage.
In conclusion, the marriage of tradition and technology plays a pivotal role in ensuring the longevity and quality of our beloved wines. From understanding the intricacies of cork quality to embracing cutting-edge spectrometry techniques, the world of wine continues to evolve, offering enthusiasts new ways to savor and appreciate the artistry encapsulated in every bottle.
