Dusting out the old liquor cabinet for the holidays in preparation for the holidays? Well, enjoy. Just don't be stupid. The hard stuff — distilled spirits such as vodka or rum or bourbon, etc. If you have an unopened bottle of Jack Daniels you bought 20 years ago, it's going to taste pretty much the same as it did the day it was bottled. Can whiskey go bad? To find the answer to your burning questions and for a better understanding of the shelf life and safe consumption, scroll below.
Unlike wine, whiskey does not get better with age. Every high proof alcohol such as whiskey, scotch , gin, triple sec , etc. The shelf life of Jack Daniels varies significantly on how it is stored. A never once opened bottle can easily last you for 10 years and above, whereas an opened bottle has a shorter shelf life of 6 months to 2 years.
Cheers Frank. Forever on my shelf I wouldn't touch the stuff! Sorry, couldn't resist. Hey no body is going to force anyone to drink anything. Now, that's an interesting question. Could it be that whisky gains its alcohol through distillation while wine gains its alcohol through fermentation? Perhaps it's the organic process of fermentation that causes it to be less stable when exposed to air. That's just a guess, though. And, thanks for not forcing me to drink Jack Danials.
Reminds me of when I was in Ireland last, and I toured the Bushmill's distillery. I volunteered for the "expanded tasting" at the end of the tour. I didn't want to because I am a bit of a whisky and whiskey buff already, and thought I would give someone else a chance If an unopened bottle of whiskey is exposed to UV light sunlight for long periods, it can cause organic compounds in the whiskey to undergo catalysing reactions that cause them to break down.
Some of these organic compounds are responsible for the wonderful flavour and aroma of whiskey. Once they break down, the whiskey loses some of its flavours and aroma. Exposure to UV light may even cause free radicals to develop in the whiskey, which can tarnish the flavour of the whiskey.
Eventually, exposure to sunlight can cause evaporation, reducing the amount of whiskey remaining in the bottle and changing its flavour even more.
It is also common for whiskey exposed to sunlight to lose its colour. Once you have opened a bottle of whiskey the alcohol that is present will begin to slowly evaporate, which will make it taste smoother.
Having a smoother tasting whiskey is usually a good thing and the reason why people often decant a newly opened bottle of whiskey. An opened bottle of whiskey will also begin to oxidise.
This is the process that occurs when oxygen interacts with the compounds within the whiskey. This can have an unpredictable effect on a spirit, sometimes making it taste better, other times making it taste worse.
