So the questions becomes, what to do? Well you could always dig yourself a hole, not a good thing to do when you're in conversation [aka, argument] with your significant other, but in this case it just may be the ticket to finding that "right-size" cellar so many collectors or cork-dorks would [need] love to have. For many folks [cork-dorks like me], [not all] the truth is that many of us don’t have the room necessary to store another case of wine in our [collective] nearing over-capacity [above ground] storage systems or just don't have another place in your home to build an above ground cellar in a spare room and you don't want to convert that nursery quite yet. So what can be done, order another Eurocave or another storage system? Maybe, but what if you are just flat out of space? This system from Spiral Cellars seems like a great alternative and I've outlined some pros and cons below.
Well then I may have the answer you’ve been looking for, a visit from the folks at Spiral Cellars who can for about 30k [ouch] on average, get to the bottom [literally] of your wine storage issue[s]. That said, seriously think about this unique option, which would make you the talk of the town in cork-dork circles. So here's the idea you can build a deep, dank dungeon, with a trap door no less, into your kitchen floor and of course your significant other will be so pleased with this idea, wink, wink! Seriously though, check out this option at Spiral Cellars . This appears to be a great (albeit, initially expensive) way to keep your wine chilling at the right temperature, save on energy costs and be "green-minded" all in one fell swoop.
Cons: Okay yes there's a downside, as with everything in life. The cost is a bit prohibitive for a large majority of folks, including myself. Second, digging a hole down into the foundation of your home may not be the best idea for structural integrity no matter what their engineer's tell you. Third, well your friends or family may think you're just a kook [or eccentric at best] and further conclude that you should be heading to AA meetings to consult with your higher power.
My Recommendation: First take a look at this video, call them to discuss the potential project and then starting saving some serious coin or I would say you could take an equity line of credit on your home, but those days for many are long gone [completely different topic]. If you can afford it I would say I definitely recommend it enthusiastically.
