Agree with Nautilus
Regardless of where you put in the fridge, it is way too cold. Fridges tend to be in the single digits while wine storage should be between 12-15 degrees. If you intend to do more long term aging, especially if you want to get into Bordeaux wines or more premium wines from around the world, it is very highly recommended and encouraged to get a proper wine storage unit or at least rent wine storage space offsite (ie: ExtraSpace) to preserve your hard earned money to its fullest potential.
There is a reason why people wax lyrical about good aged Bordeaux, burgundies, Barolos, Rieslings etc...because of the multitude of complexities and flavours and finesse they get from them. Most of us (me included) tend to drink good wines early mainly because we’re impatient, we tend to only buy a bottle or two or don’t have proper storage. But if you have tasted a good aged wine, you will understand why and you will desperately wait for that special bottle you have to come of age before opening it, or search high and low among wine collectors/retailers to see if they have any old gems they are willing to sell at a special price.
Thankfully I had a couple of those experiences where I managed to snag an old bottle at a good price, or someone let me taste an aged wine or even opening a bottle that I thought was past its prime. The revelation was enlightening; too bad i don’t get enough of such experiences.
I suspect a number of people who are getting into wines and want to buy more expensive wine to age tend to forget about the storage conditions needed. So if you wish to experiences such indulgent pleasures with that special and expensive bottle that you bought, do consider getting proper storage to let your money reach its full potential.
@AhnNakata7: perhaps you could try brands such as Kadeka or if you have the budget, you could go for a Vintec or Eurocave. Retailers and Distributors such as Parisilk, Enoteca and Crystal Wines carry them.
