I have a 55bt wine chest and only cellar wine as I am not the biggest "cellarable" beer fan**. But I have tasted many aged big beers that knock my socks off. I just haven't put the effort into aging many myself and don't brew many beers over 1.060. Once in a blue moon I make a style such as a tripel or RIS that is still "easy drinking" at 1.075+ but it is kegged or quick growler'd and drank within 6-12mo.
**At this time.
When time/ money permits or tastes change I will move towards a build similar to house all my "consumables" I have pondered even larger setups and find that yours is "just right" you can fit many wines and plenty beers and it is not a major cost/ labor undertaking. Thanks for the post/ photos the glass doors are classy.
