I ask because we are thinking of simply building walls around our current wine racks in the corner of the cellar to store them while we're out of the country for a few years. Yes, I will have to trust the tenants, but colleagues have done what we're considering and all has gone well. The storage would be written into the lease.
I thought about buying a Vinocellar but for less money, perhaps much less, we can build a cold cellar which would offer more potential uses. And we'd still have to trust the tenants. Besides, how would I ever get my vinocellar out of the basement if we sold the house? Off-site storage for my current holdings would be about $1000 a year which seems expensive.
