Popular home wine inventory systems include Vinotheque, Vinotemp, Le Cache, and Eurocave. These units provide racking measured in rows and slots, varying in bottle slot-depth and space for open storage to accommodate magnums. Full redwood racking is the ideal.
Wine Inventory Systems: Reviews & Testimonials

Common among our clients are cellars in dire need of organization and proper wine inventory systems. An ordered cellar adds to the enjoyment of a collection and helps locate that bottle you need immediately. It ensures that wines do not cellar past their prime...
Warren Porter, Iron Gate Private Wine Management
"Intuitively designed....with the touch of a button, eSommelier can keep you up-to-date on your wine cellar inventory, evaluate the total value of your collection, and remind you where you stored a specific bottle."
Jessica Taylor, the Robb Report
"Oenophiles need not be technophiles to manage their collections with eSommelier"
Michel Marriott, New York Times
"eSommelier wine inventory systems can be accessed from any networked devices in the home, as well as from anywhere around the world. This is particularly useful for collectors that have either a second home or store their wine collection off site. Searching for a particular bottle for dinner is also a simple task."
