I am new to the world of whisky (trying to learn as much as possible) and have a few questions about some whisky discovered in my parents liquor cabinet as they prepare to move. Please forgive these questions should they be too rudimentary or outlandish.
1.Amongst the discoveries was a bottle of Chivas Regal 12 year old that was purchased in 1976. Is this whisky suitable to drink? The bottle is unopened but given its contents are now 45 years old, is it still "good"?
2.Another discovery was the unopened bottle of Jameson's Crested Ten, age / purchase date unknown. I'm not familiar with "Crested Ten". If this whisky was purchased within the past 10-15 years (a vague assumption) is it still consumable?
3.Similar to the Crested Ten, there was an unopened bottle of Crown Royal, date of purchase also unknown. Will the Crown Royal go "bad"?
If any of the whisky's mentioned above at good to drink, is there shelf life that I should be aware of? Will they go "bad" in the future?
Thanks to all, I appreciate your insight & feedback.
