I've got a decent collection of whiskies going, but I don't drink them too fast. The last 4 or 5 bottles that I've picked up are unopened, and I may not open them for 10-12 months, maybe a bit longer . So, I'm hesitant to buy any new bottles . I've heard that as long as the bottles are unopened, stored in a cool dry place, with no direct sun-light exposure then they should last no problem. Is this true?

My question is what consitutes "extreme" temperatures?
Another good question.
To avoid that risk, I keep my unopened bottles in the basement where the temperature never gets above 65 F, even on the hottest day and never falls below 50 F during the winter. I think they'll be fine, even after many many years. At least I hope so...
I'd guess it's safe to keep quite a period of time (cool & dark place as mentioned).
Some friends seem to regularly bump into items that still have the old tax seals around the cap, and generously break them open to study. Of course... almost all of these sorts, I'm not well versed with or have had ample comparisons with bottles purchased / consumed closer to real production & bottle dates.
Without being able to say for certain there was absolutely no time related change, I don't ever recall a sample that we tested that gave me the impression there was air damage or deterioration / falling apart of the delivered spirit.
In fact, even stored in relatively extreme temperatures and IN sunlight, they'll probably last a good while -- but why risk THAT?! High-proof (abv) spirit is -- at least, vis-a-vis wine -- almost inert. It won't change readily, unopened. As examples, I opened among friends several bottles last weekend over 50 years old. All were fine, a couple stellar. Since I've had them, they've simply sat on a computer-room shelf. Just don't store them on their sides -- whisk(e)y/alcohol is a solvent, and it will interact negatively with a cork, though perhaps very slowly.
My Dad had two bottles of Jack Daniels (unopened) from the late 80's. The JD then was at 44%, and I wanted to open up one of these bottles and taste it. The result was Jack that tasted better then the Jack of today. I think as long as you dont crack the seal, store it out of direct sunlight in a cool place the life span should be many years.
