If no suitable naturally cool space is available, there are any number of active temperature controlled devices available. If larger capacities are desired, prefabricated rooms which include the insulated walls, racking, and cooling device, can be provided. When buying or designing a temperature controlled cellar, serious thought should be given as to the future capacity requirements. You don't want to outgrow your space in a year. It is generally more efficient, both in cost and space, to buy one large unit rather than two smaller ones of equal capacity.
Sound level is another consideration.
Units will vary from a slightly discernible hum, to the sound of an air condition. Along with location, this must be taken into account. The type and style of racking should be considered as well. If one buys wine by the case, space should be left for case stacking either on the floor or on shelving. Those who have many of the same bottles can use bulk bins, which can hold anywhere from 10 to 32 bottles per hole.
