Does Cooking Sherry Go Bad?
Cooking sherry is a type of fortified wine that is commonly used in cooking and culinary preparations. It is known for its rich, full-bodied flavor and its ability to enhance the taste of a wide range of dishes.

In this article, we will explore whether cooking sherry goes bad, how to tell when it has gone bad, and what to do if you suspect that your cooking sherry has expired or spoiled.
Direct Answer: Does Cooking Sherry Go Bad?
The answer to this question is a resounding "yes". Cooking sherry can and does go bad. While it is not perishable in the same sense as fresh produce, cooking sherry is a sensitive product that can be affected by factors such as oxidation, contamination, and chemical degradation. Over time, the flavor, aroma, and color of cooking sherry can change, causing it to become spoiled and undrinkable.
Why Does Cooking Sherry Go Bad?
There are several reasons why cooking sherry can go bad. Some of the most common causes of spoilage include:
• Oxidation: When cooking sherry is exposed to air, the tannins in the wine can react with the oxygen, causing the flavor to become bitter and astringent.
• Contamination: If the cork or cap on the cooking sherry is damaged or compromised, bacteria, yeast, or mold can contaminate the wine, causing it to become spoiled.
• Temperature Fluctuations: Exposure to extreme temperatures can cause the cooking sherry to become unstable and go bad. For example, sudden temperature changes can cause the wine to expand or contract, which can lead to corks popping or leakage.
• Chemical Degradation: Cooking sherry contains a mixture of wine, sugar, and sulfur dioxide, which can degrade over time. As the wine ages, the sugar can break down into unwanted compounds, affecting the flavor and aroma.
