Wine Bottle Riddling Rack, these are used to store bottles at just the right angle in champagne cellars. I've seen both vintage & reproductions (like this one from pottery barn) all over the web. What a cool addition this would be, while displaying my interest in wine.
Combined Custom and Prefabricated Cellar This is a classic wine cellar that uses prefabricated and custom components. Once again, the system used here is scalable, and probably what you're most used to seeing in a traditional wine cellar. The storage system is made of ready-to-order components that come in pine, cherry, redwood and mahogany.
