Yes, this was a few left over bottles, just don't know what happened besides the temperature going up (and yes they had peaked a few monthes earlier). The storing prior to this had been between 6-10 degrees. I heard that storing ales and lagers could/should be done in different temperatures (ales on the warmer side).
For aging darker stronger ales a cooler area, say in your basement if you have one is best, and be sure to keep it in the dark, light is the enemy of beer, especially lighter colored beers.
Lagers, well, Lagering literally means to condition cold for a period of time.
For brews that are hop forward (be it bitterness, flavor, and or aroma), no matter what yeast they are fermented with, storing and aging will yield negative results.
Hop flavor, aroma, and bitterness will fade over time.
Case in point, I have a Black IPA on tap at the moment. A buddy came over and brought the same beer that I had bottled about a year ago. So we did a side by side taste test. I told him, you will be surprised at how much better the new brew will be.
I was not surprised at all that the bitterness, aroma, and flavor were nearly non existent on the year old brew.
My buddy gave me the "holy shit" look, what a difference he said.
I told him, "unless I tell you to age a beer in future, get it in you before it fades!"
It was still a good beer as it had been in his fridge all that time, and it was dark, but it tasted a bit more like a stout/porter mix.
