Do some whiskeys change flavor after they are opened?
I bought a bottle of Ardbeg Uigeadail and loved it.
Now it seems hot and missing some of the sweetness and complexity it had when first opened. It's only been about 5 or 6 weeks since I opened it

So here is what chatGPT (or whatever it is said)
Oxygen can also have an effect on whiskey, but it's a bit more complicated than with wine. When whiskey is first distilled and put into barrels, it's a clear liquid with little to no color. The color and flavor of whiskey come from the barrel aging process, where the liquid interacts with the wood.
During the aging process, oxygen enters the barrel and interacts with the whiskey, causing a chemical reaction called oxidation.

This process can help to mellow out the harsh flavors and aromas of the whiskey and can bring out more subtle and complex flavors.
However, too much oxygen exposure can lead to over-oxidation, which can result in a loss of flavor and quality. This is why whiskey is typically aged in barrels that have been charred on the inside - the charred wood helps to regulate the amount of oxygen that enters the barrel and interacts with the whiskey.
