My family and I were going through my grandmother’s apartment after her passing to get her estate in order. After all was said and done, I got a bunch of alcohol she had for guests mostly, including two types of whiskey (scotch and regular), some gin, and three flavors of vodka. I tried some of the Crown Royal and it didn’t taste too good. Also didn’t taste like the last glass of whiskey I had before. Of course I always hear about stuff aged 4 years or 12 years etc. so I wonder if it’s a “gone bad” thing or a me thing.
If there’s enough alcohol in it, that will keep bacteria etc out, so it’s probably safe to drink. But ageing happens inside a wooden barrel or something like that. Inside of a opened bottle, it can lose or change flavor over time. But I’m not sure if that’s the case here. It’ll take some years. And there is a wide variety of tastes in whiskey, so maybe you tasted a different sort of whiskey? Or it really went bad… I’ve never had “Crown Royal”. Maybe let someone taste who knows how it’s supposed to taste.
