For the most part, most wines are made to be drunk right away. When you get into the $$$ models and some of upper $$, these can be made to lay down to enjoy later, if properly stored. I'm sorry I didn't see this thread back in April.
High temperatures hasten the aging process as well as light and vibration,and wide swings in temperature. Custom cellars allow for for no more than 3-4 degrees range. If you enjoy those models and wish to protect your "investment", a storage cellar would be suggested. These tabernacle style units keep your units 50-60 degrees with a 57% humidity so your corks don't dry out or mold. (Nothing like having a dry or moldy old cork, so I'm told.)
The above mentioned wine fridges are nice, but those are really just "temporary" temp controlled boxes and not for years of storage. But going to the next level poses other caveats. Unless you purchased the wine directly from the winery, in your hands to your cellar, you have absolutely no idea if your wine sat on the dock in the warehouse for 6 hours, or was kept in a controlled environment. You don't know if was hauled in a reefer from California, or a trailer with plastic or canvas sides. Your Bordeaux got here by plane or boat, how much vibration did it suffer through? Are you trained/talented enough to even tell the difference? How would you know if your wine was abused before you put it in your cellar?
So, keep your storage area cool, away from direct, bright and florescent lights. If the winemaker did not cold stabilize his wines, as grasshopper mentioned, tartrate crystals will drop out of the if the wine was stored in a fridge. They are harmless, but it will change the acidity of the wine and its crispness.
As much as I hate to say it, though, it is only wine. I have about 1500 bottles of wine in my cellar, about 1400 bottles that I made over the past 8 years.Stored in my cellar, they see temps 55-63 degrees. The others, I know how they traveled. They are not priceless, but very good products that DW and I enjoy with friends and family.
Prepare for the next bargain you might stumble upon. You might try monitoring a summer cooler placed in a basement closet with some blankets or insulation around it. You can put a thermometer with a long probe.
