IME/IMO, it depends on what you're looking for in the aging. I do it in the basement, which used to be in the mid 50's for most of the year. With some different hardware adds in the basement here, that's been elevated to a higher temp. Especially in the summer. But, if you've added oak elements (cubes, staves, spirals) then temperature swings can actually be a good thing. Just like how whiskey is aged where it changes temperature with the seasons, moving in and out of the wood with temperatures.
I bulk age my mead batches as long as possible before it goes into bottles. I have some that were started as far back as 2012 that are still in bulk. I added oak cubes to them almost a year ago now. I plan to pull tasting samples this weekend to see if they're ready for bottling or not.
