How long does a bottle of alcohol Crown Royal last if unopened with the seal intact and dated 1966?

A bottle of alcohol, such as Crown Royal, can last indefinitely if it remains unopened and the seal is intact. The alcohol content in Crown Royal acts as a preservative, preventing spoilage and maintaining the quality of the liquid. However, it's important to note that the taste and aroma of the whiskey may evolve over time due to the aging process. Some connoisseurs argue that older whiskeys can develop a more complex flavor profile, while others prefer the taste of younger whiskeys. Ultimately, the experience of drinking an aged whiskey is subjective and depends on personal preferences. If the bottle of Crown Royal from 1966 has been properly stored in a cool, dark place and has not been exposed to extreme temperatures or fluctuations, it should be safe to consume, although its taste and aroma may have changed slightly.
