Does it hurt white wine that was stored at room temp then chilled on ice but never opened to be returned to storing at room temp again?

While storing white wine at room temperature is not ideal, chilling it on ice after having been stored at room temperature should not significantly harm the wine, especially if it was never opened. However, repeated temperature fluctuations can potentially affect the wine’s quality over time. It's best to keep white wine consistently stored at cooler temperatures for optimal flavor and longevity. If it was only chilled once, it should be fine to return it to room temperature for a period.
