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.
It may change taste profile depending on heat and sun/light exposure but it’s still alcohol unless the bottle is compromised and it evaporated.
Aging refers strictly to how long the alcohol was left in a barrel before being put into a glass bottle. A 10 year old bottle of scotch is still only a 10 year old even if it was bought in 1970.
I’ll add in her something I learned recently - whisky can become “corked”, ie if the stopper is made of cork, it can go bad and ruin the drink’s flavour. I thought this was just a wine thing, but apparently it can happen with whisky too.
I’d have to wonder if storing a corked bottle of whiskey at an angle to keep the cork wet like with wine keeps it intact.
What we know as whisky maturation is a dance between 4 interrelated processes - infusion, evaporation, oxidation, and other chemical reactions. These all happen together, and very nicely, when whisky sits in oak barrels for an extended period of time.
Colour, and oak flavour are infused into the whisky simply by sitting in the barrel. The whisky will slowly evaporate while inside the barrel as well. Volatile compounds evaporate, making the whisky smoother, deeper, and more complex with age. Fascinating chemical reactions happen between compounds in the wood, and in the whisky. As ethanol degrades lignin, for example, it creates new compounds, which themselves interact with other molecules and compounds in solution.
The age statement on a bottle of whisky refers to the time it spent in a barrel, doing those lovely things.
Common wisdom is that the whisky is done changing when it goes into glass. Certainly, infusion and evaporation are finished. But! Oxidation, and reactions between compounds in the whisky itself will continue, even in a sealed glass bottle. Usually this happens too slowly to notice, or the bottle gets drank before a change can be observed, but change certainly happens.
Long story short - whisky won’t go bad. In fact, sometimes it even goes ‘good’! I had the chance to try a young single malt, that was bottled in the 1970s. It was wonderful, and had signature aroma and flavour characteristics of a very old whisky. This is due to slow oxidation, and the glacial interaction between esters and congeners over time, which will happen no matter what vessel the whisky is in.
Whisky that has been exposed to too much oxygen, like if the bottle sits nearly empty for a long time, or has a bad seal, will often end up tasting flat and bland. But ‘good’ or ‘bad’ at this point, is a subjective matter. Only one way to find out!
Explains that one time I had a bottle of disgusting flavoured whiskey, let it sit half-empty for a few weeks or even months, and then it was actually pretty good
Could be! From my experience, high strength Bourbon is better a couple weeks after being opened. From a flavour standpoint, gin also benefits greatly from resting for a few weeks after distillation.
In fact, one of my favourite Scotch Whisky distilleries will blend a production batch, and then re-barrel the blended volume in casks and let it rest for 6 months to allow the flavours to harmonize.
There is definitely some magic that happens after spirits are blended/bottled, and it’s not very well understood, but the changes are detectable, and in general, they’re positive.
Alcohol can’t expire, expiration is a part of how it’s made. In most of these cases the expiration date is actually for the container.
If the container looks fine and nothing has gotten into it, it’s no more dangerous to you than alcohol normally is. Same goes for vinegar and many other similar things. For example honey can’t go bad in a sealed bottle, but the bottle can degrade and let things in.
This is not exactly true, alcohol can become vinegar if exposed to oxygen, and I doubt those bottles are properly hermetically sealed.
You’ve obviously gotten the base level answer, but to add some color here - certain types of food, such as dried pasta, rice, beans, grains, high proof alcohol, vinegars, and basically anything frozen to name a few, never spoil in the sense that they’re unsafe to eat.
Flavor, however, is an entirely different matter. Just ask anyone who has eaten freezer burnt food.
Pretty much any high proof alcohol will fall into this category. And, if it’s unopened, it should retain most of its flavor for a very long time. Once opened, however, it can deteriorate relatively quickly, depending on how it was stored.
Your list of semi non-perishable foods does need some caveats about storage, because most of those things can go bad, depending on how they were stored.
Frozen meat can spoil, as not all bacterial growth stops, some just slows down a whole lot. So if Grandma threw in a store plastic wrapped tray of chicken quarters, after being in the fridge for 3 days, and now it’s 8 years later, those might not be safe for human consumption.
Stuff that was vacuum sealed, much more likely to last the long haul in the freezer, if done properly.
Long-term stored grain, when not in vacuum sealed or other airtight containers, can develop molds or other bacterial contaminations.
Improperly stored vinegar, if you try to use it…it will ruin your salad dressing, and taste like shit. But it’s pretty easy to see if vinegar has gone ick.
Can’t say I’ve ever seen moldy or spoiled vinegar, but I’ve seen the type of kitchens that would be capable of making it happen in a long enough time frame.
I’ve also never seen bad dry storage pasta or beans, but I imagine they carry the same long-term storage concerns as grains, even if they’re probably a bit more durable.
Sorry about your grandmother! Sending heartfelt condolences ❤️
As others have said, beverages such as whiskey are generally considered to be non-perishable due to their high alcohol content. They won’t “go bad” in the sense that they’ll be harmful to you if you drink them, but the flavor may change after a long time. If you have pleasant memories of your grandmother, I’d keep them in a sturdy box that’s for sentimental items!
